⚡ Inside GitHub’s AI Revolution: Jared Palmer Reveals Agent HQ & The Future of Coding Agents

Jared Palmer

YouTube
TL;DR
  • GitHub is positioning Agent HQ as a hoped-for home for coding agents and developers, not merely another first-party assistant. The host cites 183 million developers, while Jared Palmer says GitHub has over 180 million. Jared says GitHub can pair Copilot and Copilot CLI with third-party harnesses including Claude Code, Codex, and Devin, creating a “gravity well” for agents and developers. The strategic asset is workflow ownership plus agent choice, rather than dependence on one model.
  • V0’s history suggests model progress monetized explosively only after product form and scope caught up. Jared says the initial product took roughly nine months to reach $1 million ARR; the host says that after models could support chat, a rewrite added “another million” roughly every 14 days and became “a rocket ship.” Jared credits the deliberately narrow focus on Next.js, frontend, and shadcn: “That constraint was rather liberating.”
  • The relevant abstraction is shifting from a model switcher to a tightly coupled agent with compute, files, tools, and a runtime. The discussion argues that loose model interfaces collapse toward the lowest common denominator. Jared calls the coding-agent setup a distinct “agent world,” with sandboxing, file systems, and tool calls. Value therefore shifts toward harnesses, specialist subsystems, evaluations, and infrastructure around the model.
  • GitHub’s near-term wedge is ambient AI across the software lifecycle, with VS Code integration as leverage. The demonstrated flow sends an Agent HQ task into a pull request and opens it in VS Code with one click; Jared also points to issue assignment, merge conflicts, and broken Actions as intervention points. His focus for roughly the next six months is AI sprinkled “salt-bae style” through mobile, web, GitHub.com, and editors.
  • Reliability, not another flashy modality, is the remaining slope from 90% success to “nines of success.” Jared’s answer to what comes after today’s coding agents is simply “making them good”: the gap between 98% and 99% correctness is noticeable, while multi-turn sessions amplify provider failures. At Vercel, key metrics rolled up about every three hours, including error-free sessions, latency, dropped requests, and infrastructure errors.
  • Reproducible repository setup remains an unsolved infrastructure bottleneck, and dev containers are promising without yet being the standard. A focused Next.js system can assume a package-install path; a general agent cannot predict whether a repository quietly needs something like ffmpeg. The discussion notes competing runtime approaches inside Microsoft and points to shared defaults, autodetection, and preemption as open opportunities.
  • GitHub is pairing Agent HQ with overdue core-product repairs, but its scale makes even popular requests expensive to land. A redesigned homepage now emphasizes tasks and recent pull requests, while stacked diffs—the community’s top feature request—are back under active exploration. Internal attempts date to 2020, including a polished 2022 implementation deemed too risky because it introduced stacks outside pull requests.
Digest · the substance, structured for research

1. V0’s narrow constraint converted model progress into a product

  • Jared’s origin story predates any Vercel AI group: while directing engineering across Next.js, Turborepo, Turbopack, webpack, and internal tooling, he turned a Server Actions dogfooding exercise into an AI playground. Guillermo’s news that nat.dev would launch Monday forced him to ship; the exercise made him work through every provider’s API and streaming quirks.

  • That playground became AI SDK because Jared had already isolated the reusable streaming layer without forcing developers into one provider. Its niche was the UI layer: useful abstractions without getting in the developer’s way. An open-source ChatGPT template built with shadcn then gave the small team a full-featured base for rapid experimentation: “It was liberating.”

  • Code Interpreter sparked the original generative-UI thesis: code execution could emit tabular data, another prompt could render it, and outputs might pipe together. Yet tool calls did not exist, the context window was 4,000 tokens—later about 16,000—and internet-enabled execution triggered a security debate. The code-execution idea was shelved; prompt-to-UI became v0’s “aha moment.”

  • Around September 2023, v0 launched as “Midjourney for React,” using selectable visual variants because reliable chat still was not available. Progress through GPT-4 and GPT-4 32K changed the ceiling, though Jared admits, “We never really got GPT-4 Turbo working—I don’t know why.”

  • Commercially, Jared says the first version took roughly nine months to reach $1 million ARR. The host then says that once models could sustain chat and the artifact pattern matured, the team rewrote the product; the relaunch added “another million” roughly every 14 days and became “a rocket ship.” The durable edge was focus on Next.js, frontend, and shadcn. The host also says Vercel shared its post-training harness and hygienic data with frontier labs.

2. The agent is replacing the standalone model as the product unit

  • The conversation describes a debate between combining the best qualities of different models and exposing a model selector. A composite permits specialist subsystems—search need not use the generation model—can improve performance by stitching components together, and gives the product a brand it controls.

  • The economics cut both ways. A branded provider model can earn co-launch promotion, but billing is effectively anchored near that provider’s retail price, limiting the premium. Jared adds that a composite can support a sustainable business independent of model labs while genuinely improving performance.

  • The hosts argue that the model layer is no longer the right switching abstraction: models and agent harnesses need to be “very, very strongly coupled,” or a generic interface inherits the lowest common denominator. Jared characterizes the coding-agent setup as a distinct “agent world” involving loops, compute runtimes, files, sandboxing, and tool calls.

  • Agent HQ reflects that shift. GitHub supplies Copilot and Copilot CLI while also accommodating third-party harnesses such as Claude Code, Codex, and Devin. Jared hopes it becomes “the home” of agents and developers, offering choice rather than forcing one first-party stack.

  • Skills push the interface down another layer: the host frames them as an LLM-native bundle where an agent reads Markdown and a directory of files, making the filesystem a universal interface. The discussion highlights MCP as an important enterprise-context mechanism, while GitHub’s announced custom agents can combine task-specific prompts with MCP capabilities.

3. GitHub’s advantage is owning the seams between development tools

  • V0 optimized one framework and one problem; GitHub spans all languages, frameworks, and the 183 million developers cited by the host. Jared, only on day 13, calls that scale “immense” and places Agent HQ in a broader Microsoft CoreAI organization containing GitHub, Visual Studio, VS Code, and parts of Azure.

  • The intended experience is continuous rather than destination-based: launch a task, receive a pull request, then open it in VS Code with one click. Jared wants AI inserted at existing friction points—assigning issues, resolving merge conflicts, or repairing an Action that fails remotely but not locally—without pulling developers out of flow.

  • His roughly six-month focus is seamless movement across mobile, GitHub.com, the web, and a local editor. The memorable framing is AI sprinkled into native workflows “salt-bae style,” with Agent HQ and GitHub co-evolving rather than operating as an isolated agent dashboard.

  • Jared calls dev containers an important lightweight sandboxing concept and asks whether they should become a standard. The host points out that they can bundle VS Code, a filesystem, sandboxing, security controls, and GitHub Enterprise connectivity, while also noting competing runtime approaches inside Microsoft.

  • Jared identifies repository setup as Cognition’s number-one pain point, and says Codex and presumably other agents face it too. He notes that a Next.js specialist can often assume npm install; the host explains that a general system cannot predict hidden dependencies such as ffmpeg. The discussion points to autodetection, preemption, and shared defaults, while the host recalls an unrealized idea for an open-source framework detector that could move the ecosystem together from npm to Bun.

4. Better agents require reliability engineering, not just smarter models

  • Asked what follows the progression from Copilot to more autonomous coding agents, Jared rejects the hunt for a dramatic new category: “Making them good.” Moving from 90% to 95%, 98%, 99%, and eventually “nines of success” becomes progressively steeper, and “there is a big difference between 98% and 99% correct.”

  • His warning is that many AI teams are “living in La La Land” about quality because they do not measure error-free sessions, provider failures, dropped requests, or latency. At Vercel, key metrics rolled up about every three hours—an almost “video game style” operating loop that made a good or bad day immediately visible.

  • Infrastructure reliability is part of model quality because inference does not yet behave like a database with dependable uptime. Providers differ in both performance and availability and “go down all the time”; Jared connects the success of OpenRouter and gateway products to the need for switching and failover during multi-turn agent sessions.

  • Computer use remains a modality under discussion: Jared says it became known as slow, bad, and inaccurate but is improving, especially with open vision models such as DeepSeek-OCR and olmOCR. The host calls it computationally intensive. Jared’s emphasis remains the hard final mile: “The devil’s in the details.”

  • Jared also applies agents to personal workflows. He pointed Claude Code at his father’s accounting spreadsheets; it generated Python scripts and seemed better than ChatGPT, though it “got off the rails.” He uses agentic browsers, currently mostly Atlas while retaining Arc for its vertical tabs, and built Chrome Dump to summarize and close hundreds of tabs through Markdown. The host is surprised that data-analysis agents remain relatively underdeveloped, with organizations still in the BI era rather than querying precise analytics through a Slack bot.

5. Core GitHub workflows are being reopened for repair

  • Jared cites an RZ tweet from May 22, 2025 declaring that “pretty much the entire GitHub homepage is useless”; it drew 1.3 million views and 19,000 likes. The new homepage responds with tasks, recent pull requests, and retained elements such as recent repositories. Jared praises the overhaul while stressing, “There’s more work to do.”

  • Stacked diffs are the larger workflow fight. Jared’s analogy is a sequence of pull requests containing one commit each: developers can alter an earlier diff and restack the dependent work, with automatic restacking if the system supports it. The stack can then be collapsed and merged, and sophisticated setups can choose which layers deserve CI. For monorepos and very large codebases, that makes review and updates more fluid than conventional pull requests.

  • The request has led GitHub’s community list for years. Jared found attempts reaching back to 2020 and a polished 2022 client-side implementation that introduced stacks outside the pull-request model; it was deemed too large and risky. The feature is now being worked into planning, but GitHub’s scale and Git implementation make it “not just a walk in the park.”

  • That tension captures Jared’s operating posture: visible responsiveness without promising an easy ship. His DMs remain open because “all feedback is a gift” and “it’s all a signal”; collecting more of it should improve decisions about both Agent HQ and the less glamorous GitHub primitives underneath it.

Speaker 1

All right, we are here for a very special edition of Latent Space with my buddy Jared Palmer, SVP at GitHub and VP at Core AI at Microsoft.

Jared Palmer

Correct. Dual title.

Speaker 1

Yeah, twice the time. Is it weird to have 2 jobs?

Jared Palmer

I'm only on day 13, I think, so early days. So far, so good.

Speaker 1

So far, so good. We've been trying to get you on the podcast for 2 years, I think.

Jared Palmer

I think so. Yeah. Don't worry.

Speaker 1

Yeah, you're a busy guy. We have to do it in person. It's way better.

I should also plug that Jared fans should dig into your previous podcasts with Ken. [Laughter.]

Jared Palmer

Okay. But Ken—shout out to Ken.

Speaker 1

Before that, you were building v0 and AI SDK, and you were VP of AI at Vercel.

Jared Palmer

Yes, yes. All AI initiatives and vibes.

Speaker 1

I feel like, basically, you went from building one coding agent to now being the home for all coding agents. Is that the general vibe of Agent HQ?

Jared Palmer

I think that's right. Backing up, I spent the last 2 years or so building v0 at Vercel and AI SDK. Then this summer, I took time off, and now I've joined GitHub. Today, we launched Agent HQ, among other things, here at Universe.

It's going to be the home, we hope, of not only agents but also developers. It seems like a gravity well for this new collaboration space that we're trying to build.

Speaker 1

What do you think GitHub can do that you couldn't do at Vercel?

Jared Palmer

GitHub is an enormous platform, right?

Speaker 1

183 million?

Jared Palmer

Yeah, GitHub has over 180 million developers. The scale is immense. v0 was focused not only on one language but one framework and a specific problem space with a built-in renderer.

For those who aren't aware, v0 is like Bolt or Lovable, but it's built by Vercel and focused specifically on building Next.js apps. That constraint was rather liberating for the team at the time and let us really laser-focus on it.

Speaker 1

I hope. Thank you. I hope.

Jared Palmer

Obviously, at GitHub, we're the home of all languages, frameworks, and developers, so the scope is broadened. It's just a different part of the map, if you will.

Speaker 1

You've basically been covering the entire journey of coding agents from the start. What's your personal journey through coding agents? We started out with Copilot—obviously, GitHub started the Copilot trend. Tell us about the origin story of v0, how that developed, and maybe where you want to see things go next.

Jared Palmer

It's funny you ask that, as I've told the story multiple times. I feel like I've unlocked different parts of it in my brain by going back, so maybe we'll have to figure out how retrieval memory works.

Speaker 1

Interesting how memory works for agents.

Jared Palmer

Totally. That's why I brought it up. Sometimes you discover new paths, right? Anyway, the story goes like this.

When ChatGPT first came out, it was obviously incredible—world-changing and the fastest-growing product ever. I looked back at the timeline and dates, and we were very early in jumping into AI stuff when I was at Vercel.

At the time, there was no AI division and no AI group. I was the director of engineering for all of Vercel's frameworks, and I was helping with Next.js—spelled right?

Speaker 1

Yes.

Jared Palmer

Next.js, Turborepo, Turbopack, Webpack, and all the internal developer tools at Vercel. I was helping the Next.js team dogfood and test the initial implementation of Server Actions. Instead of building a to-do app, I was like, “Why don't you build a playground?” And I was like, “Okay, cool.”

That led to AI Playground, which is now just part of AI SDK.

Nat.dev—Guillermo told me about it. I got a DM; I remember, because I was at a bachelor party. He sent me a note saying, “Nat.dev is launching on Monday. You have to ship.” I had been working on it previously, so he was like, “Same idea.”

Speaker 1

Yeah, so he got wind of it, I guess.

Jared Palmer

I definitely had to jump into motion. We didn't even ship chat first. Guillermo sent me this DM over the weekend while I was at a bachelor party. He sent me the link to Nat.dev, this side-by-side thing, and I played with it. I was like, “Cool, okay,” so I sprang into gear and shipped AI Playground.

What was cool about AI Playground was that it forced me to go through every single model provider's API docs and figure out their quirks and nuances around streaming. At the time, it wasn't like everybody used OpenAI; they all had little quirks, though some of them were somewhat compatible. That was my first foray.

Then I launched AI Playground, and it shot to the top of Hacker News. I remember I didn't even implement chat because chat wasn't as important. It was just completions. Eventually, we added chat, and out of that project came AI SDK.

I had already looked at all the model providers and all the combinations and was like, “Okay, here's that chunk of streaming code you need.” AI SDK found that niche of asking, “How do we focus on the part that we're going to be good at, which is the UI aspect of it, but also not get in your way?”

We shipped a playground, then AI SDK launched. We're always about demos and having great starter templates at Vercel. I remember writing Guillermo and saying, “You know what would be cool? This guy, shadcn—he seems amazing, and his UI library is doing great. Why don't we team up and ship a ChatGPT clone open source?”

We did. We shipped this awesome template, which is now called Chat SDK, and it's great. What that did at Vercel was set us up for rapid experimentation, because we had this really good, pretty full-featured, ChatGPT-ready template with all the latest features.

When it came to rapid prototyping that summer—now we're in summer 2023—it was liberating. By that point, I had gained some momentum internally and pivoted almost entirely to AI. I had Shu Ding, who you're friends with, Max Leiter, and shadcn cooking.

I think code execution had just come out. I think that's my timeline.

Speaker 1

Yeah, the Code Interpreter sandbox.

Jared Palmer

Code Interpreter. That's what they called it at the time. As soon as I saw this, I had a very ambitious idea and proposal to present to Guillermo.

Mind you, tool calls didn't exist, and the context window was 4,000 tokens, so there wasn't much there. What if we had a thing where you could prompt and sometimes it would do code interpretation, then maybe it would choose to render a UI? Other times, it could render a document inline in the chat. It would just have different kinds of generative UI.

Maybe you could pipe them together, so the output of one could feed into another prompt. If we did code interpretation, we could coerce it to always emit tabular data. Maybe we could pass that to another prompt that rendered a UI.

Speaker 1

Yeah, it sounds like these are just tool calls.

Jared Palmer

That's exactly what these are.

I came back to Guillermo, and at the time we had a security debate: Should we allow code interpretation with the ability to fetch data? Giving it internet access was scary at the time. Now they're like, “Fine, whatever. Do whatever you want,” but at the time it was a little scary.

We said no to code interpretation, but the UI idea was pretty neat. That prompt-to-UI idea was the aha moment of v0. The models weren't very good, though, relative to where they are now.

That was the GPT-4 era. We were just into the GPT-4 era, and we were probably at a 16,000-token context window. You couldn't really do chat, so we had to invent this new paradigm of faking it with completions. That forced us to do the initial v0, which launched in September 2023.

It looked more like Midjourney. In fact, if you go back to the original tweet, it was “Midjourney for React.” It was all very visual, and you could click on different components and elements and reprompt. Again, we were hacking around the limitations because we didn't have chat or tool calls.

Fast-forward again: v0 launched, and then it probably took us about 9 months to get to $1 million ARR with this little team. The models progressed from GPT-4 to GPT-4 32K—the big boy. We never really got GPT-4 Turbo working; I don't know why that never happened.

Then we switched to other frontier models and started doing our own models and things like that.

Speaker 1

But fast-forward another 10 months, or 9 months or so, and then we rebased toward chat, and now the models finally could do chat. The artifact pattern had evolved, so it was time to rewrite. When we launched v0—the chat version, or the new v0, whatever you call it—it was 14 days, another $1 million ARR; 14 days, another $1 million ARR. It was like a rocket ship after that.

And that just proceeded, and we just kept cooking. That’s been the journey. We just kept perfecting, and what was really liberating for us was the focus on just one stack or one framework. When everybody else was trying to do a general-purpose coding agent, we were like, “No, we’re just going to focus on Next.js front end and shadcn.” That really allowed the team to focus. That’s the story arc.

Jared Palmer

I mean, to be fair, because Next.js is so dominant, basically everyone has to be good at Next.js, right? But being focused even right down to the UI library and component stuff like that helps a lot.

Speaker 1

We also started working with all the frontier model labs to help, because it was in Vercel’s best interest to have them be great at Next.js.

Jared Palmer

Yeah.

Speaker 1

And also because of the post-trained models—you can read about this on the Vercel blog—we had the post-training harness that we created, and we started sharing it with other model labs. We had all our data in a very hygienic state to work with them.

Jared Palmer

Did you ever debate internally—and, from my seat at Cognition, I can also see this—whether you should pick the best qualities of every model and string them together in v0, or have a model selector and let customers go back and forth?

Speaker 1

Yeah, we went back and forth on all this. I think at the end of the day, there are pros and cons.

Jared Palmer

Yeah. One of the benefits of having your own branded model, whether synthetic or composite, is that you can stitch these things together. It’s a little different now with the agentic flow, but even look at what you guys launched recently with v0, right? Search is going to be a different model than generation, but search and generation are 2 different subsystems, right? So you can have search eval be totally different.

Speaker 1

So where we’ve probably ended up now is that, for a long time, we didn’t have a model selector, and then we had our own models, which were composites, as we talked about. That would allow us to mix and match. I think that’s probably also nice because, as a product, you get to brand it.

Jared Palmer

Right, and you can decouple it from the launch of the frontier lab.

Speaker 1

Yes.

How does Cognition even bill for it? An ACU, right?

Jared Palmer

So it gets a little wonky. We could go on about pricing this stuff; it gets challenging. But the nice thing about having the brand-name model is that you get to co-launch with the provider, and they’ll hit you up.

Speaker 1

But your billing needs to be capped at whatever retail is, right? Or some—

Jared Palmer

Right, right, right. You can’t really charge too much of a premium. You can, but—

Speaker 1

Right, right. And it’s like, well, then how do we charge you for SWE-bench or something?

Jared Palmer

I think some part of it is the cynical part: you want to create a sustainable business and independence from the model labs. But the other part is genuinely that you actually do get better performance—you get to string together all these things.

Jared Palmer

Yes. Switching gears to GitHub, we’re all about model choice now and making sure that—and what’s cool is that we also have Copilot, which is our harness, and Copilot CLI. But we also have third-party harnesses like Claude Code, Codex, and Devin now in Agent HQ. So you get the best of both worlds. I think that’s going to be awesome and ultimately what people want.

Speaker 1

Yeah. I think the model layer is not the right abstraction to do the switcher anymore. It’s weird, because that’s where you started with the AI SDK.

Speaker 1

Yeah, exactly.

Speaker 2

But now the model and the agent have to be strictly tied together—very, very strongly coupled. You can’t loosely bind them and just do a generic interface, because then you’re just going to have the lowest common denominator of all the models.

Speaker 1

If you’re in the agent world—

Speaker 2

Yeah, yeah.

Speaker 1

—which may just be better than the chat world in general. Better.

Speaker 2

Agent world is a much better abstraction. I’m calling it agent world, but I mean a loop with maybe a compute runtime and files.

Speaker 1

So that’s your definition of an agent? You’re dropping your official definition here.

Jared Palmer

No, don’t put me on. My initial definition of an agent for AI—I was dying on this hill because the AI SDK, everyone else is an agent framework—was that an agent is orchestrating an API request with a queue and a for loop.

But a coding agent now has meant so much more. There are coding-agent SDKs, and you’ve got sandboxing, file systems, and tool calls. I do think that’s a uniquely different world. I’ll call that agent world.

Speaker 2

Yeah, and I think that seems to be where things are going. I even believe the Claude for Excel agent is basically related to Claude Code. I was talking to my colleague backstage, and I think it could be.

Speaker 1

It could be. I actually don’t know how it works under the hood yet, so it wouldn’t surprise me if it was.

Speaker 2

Yeah. They seem very all-in on skills, which is kind of interesting.

Jared Palmer

What do you think of skills?

Speaker 2

It’s kind of DXT, which is the bundled version of MCPs.

Jared Palmer

Okay.

Speaker 2

Wasn’t the reason you didn’t know about it that it wasn’t very popular?

Jared Palmer

Okay.

Speaker 2

Skills are kind of the second shot that’s very LLM-y. It’s like, “Just read my Markdown and read this directory of files and go nuts.” As long as it can understand that it has the capability to run code and read files, you’re good. And actually, that is the universal interface, which is a file system.

Jared Palmer

Right. Back to agent files.

Speaker 2

Yeah, which is kind of cool.

Speaker 1

Yeah. What you’re hitting at is this philosophy of our understanding of what the minimum bar for coding agents is. Over the last 2 years, you’ve lived this journey, and now you’re basically the kingmaker.

Jared Palmer

I don’t know about that.

Speaker 1

You run Agent HQ, and I imagine you have other projects too, but Agent HQ is the big one that we’re talking about here. What are you seeing from the different agents, and what do you want this to become?

Jared Palmer

Such a good question. I think Agent HQ and GitHub itself need to co-evolve. One of the things that Microsoft has done really well is putting things that are alike closer together. Think about the new CoreAI organization: Visual Studio, Visual Studio Code, GitHub, and parts of Azure are all in one. Obviously, the GitHub team and the VS Code team have been working closely together for a long time, but now we’re really close together.

For me, one of the cooler things that Agent HQ can offer is seamlessness and fluidity with your workflow. If you saw the demo today, we saw a demonstration where you use Agent HQ, fire off a task, and it creates a PR, but you can also open that PR up in VS Code with one click. That’s awesome.

I think the vision for GitHub as it evolves is to look at those touch points where AI can be sprinkled in, in a Salt Bae-style, into the native workflow. Whether you’re assigning an issue, or maybe some new stuff that we should focus on, could be: How do we resolve a merge conflict?

Jared Palmer

Oh my God.

Speaker 2

Right? How do we maybe pop open an action or get in? We’ve all been in that flow where Actions don’t work locally. What if we could just put in a comment or kick off a task to solve this for you? What I’m trying to describe is a workflow where it’s seamless and fluid, and you can stay in a flow state across all devices—mobile, the web on GitHub.com, or in your local editor. That’s where my focus is going to be for the next 6 months or so.

Jared Palmer

Yeah. As a side tangent, one of the things Microsoft also owns—I don’t know if it’s Microsoft or GitHub—is dev containers. I think a very important concept for sandboxing environments, whatever you call it, is a lightweight version of what Docker containers are. Do you see that as a standard that we should invest in? It’s supported in VS Code, but I don’t think it’s that popular outside of VS Code.

Speaker 1

Yeah. It's used internally at GitHub too for development at GitHub.

Jared Palmer

Oh, yeah. Yeah.

Speaker 1

Which is cool. I think they were so far ahead, but now there are sandboxes. There are so many of them these days, right? I think Cloudflare just launched theirs. There's Daytona, and there's Modal, which I think Lovable uses.

Jared Palmer

I have no idea.

Speaker 1

Yeah. You probably have your own. I don't know. What do you guys use?

Jared Palmer

Just some Kubernetes pods.

Speaker 1

Okay. You guys roll it yourselves. Cool. I think that's maybe the runtime, but there's work and discussion about what that runtime should be, even internally at Microsoft. We've got a couple of different competing things, so we'll figure it out in the next cycle here.

But there's a great point: there's a lot of cool stuff in a dev container. You already have VS Code loaded, you've got a file system, you've got a sandbox, you've got the security protocol, and it's also wired into GitHub Enterprise.

Jared Palmer

Yeah.

Speaker 1

It's ready to be packaged, so there's lots of goodness there.

Jared Palmer

Yeah. I say the number-one pain point that Cognition has—but Codex and presumably the other guys do too—is repo setup, which is effectively what dev containers and a Dockerfile do for you: run this thing, then that thing, set this up, do that thing. Why is it so hard? Why haven't we solved it?

Speaker 1

I don't know. I think it's hard because you can't predict what's in the repo, right? You don't know when they bundled FFmpeg. You just don't know.

Jared Palmer

It's nice when it's just Next.js and you can run npm install.

Speaker 1

Correct. Correct. You can make optimizations with obvious constraints, and I think the general-purpose container is just challenging. That being said, there's probably some work to do on autodetection and preempting and stuff like that, but it's a bigger, broader problem space, right?

Jared Palmer

Yeah.

Speaker 1

So, fun fact: when I was at Netlify, I actually wanted to reach out to Vercel to do a standardized, open-source autodetection system for frameworks. We never got internal momentum on that. It was an idea. I was like, “Shouldn't this be open source?”

Jared Palmer

Yeah. Yeah.

Speaker 1

Autodetection is a common utility that everyone needs.

Jared Palmer

Yes. Yes, I remember that. I'm having a flashback.

Speaker 1

Yeah. Everyone knows theirs. Yes, probably we shouldn't all build it, right?

Jared Palmer

No, it's—what are your defaults? They're not exactly the same, which would be better to—

Speaker 1

Just having even the same preference stack of defaults would be the right thing. Yeah.

Jared Palmer

It would be great, because then we can move the whole ecosystem together from npm to Bun, right?

Speaker 1

Are there other movements, protocols, or standards that you're interested in? MCP was a big winner this year. There are others, like A2A and ACP. All of these are interesting. I'm not as familiar with ACP, the payments one. Is that the x402 one?

Oh, no, the x402 one. The—

Jared Palmer

The one. Okay.

Speaker 1

And then the payment one—was it Stripe or Coinbase? Stripe. Yeah, that's very cool.

Jared Palmer

We've had them on the pod.

Speaker 1

Okay. Yeah, that's very cool. It would be interesting to see if that takes off.

Jared Palmer

I mean, it's right. So—

Speaker 1

Yeah, but it still needs to be adopted by the clients, right? I think that's fascinating. MCP is huge. It seems like it's the way that a lot of our enterprise customers, especially when it comes to digital transformation, will be able to add context.

In addition to that, we also have custom agents that we announced today. You can work with prompts and stuff within your Agent HQ and customize these agents for different tasks. Those can have MCPs and such, and I think that's going to be really powerful from a platform perspective. That gets me excited. That's what I think is shipping now and next, but we're always on the lookout for the next thing. What's top of mind for you?

Jared Palmer

For standards or—

Speaker 1

Standards.

Jared Palmer

Standards should be: a container is a container.

Speaker 1

It's the—

Jared Palmer

Look, I think dev containers just have a PR problem.

Speaker 1

It's a great idea.

Jared Palmer

Right.

Speaker 1

Just no one—

Jared Palmer

Makes it interesting. I think you can do it, basically, with this one.

Okay, added to my list. But before that, you probably have a bunch of other stuff that I do want to get to. Just staying on the AI stuff, I think we're actively exploring computer use as a thing. It got going a little bit, people were very excited, and then they found out it was slow, bad, and inaccurate.

Speaker 1

It is computationally intensive, my understanding.

Jared Palmer

It's getting better.

Speaker 1

Yeah.

Jared Palmer

Especially with open vision models like DeepSeek-OCR and olmOCR. Just give it a few more turns of scaling.

Speaker 1

It seems like you need that use case, and primarily it just seems like a modality worth pursuing. A lot of people on the code generation and code agent side are trying to think about this. We had this evolution from Copilot to more agentic systems, sort of like a Claude Code situation. What's next? What's the obvious next step?

Jared Palmer

Making them good.

Speaker 1

Making them good. Yeah. You don't like Claude Code?

Jared Palmer

No, I don't. It's more that the devil's in the details.

Speaker 1

Yeah. Going from 90%—it's like hill climbing; it gets steeper.

Jared Palmer

In my opinion, it gets steeper. Going from 90% success to 95%, to 98%, to 99%, to nines of success—

Speaker 1

Yeah.

Jared Palmer

I mean, it's really hard.

Speaker 1

I mean, it's really hard, paying a lot of money for expert programmers or open-source maintainers.

Jared Palmer

Then you realize along the way maybe the users aren't that good at it.

Speaker 1

Yeah.

Jared Palmer

No, but I just think there's a lot of work to do to finish the swing. There is a big difference between 98% and 99% correct, and that's noticeable.

If you're working on an AI product, you probably don't realize how poor the quality of your AI product is lately. Most people are blind, living in La La Land, unless they're really measuring the number of error-free sessions, how many errors are coming from the infrastructure providers, how many requests are dropped, and how fast these things are. That's something we cared about at Vercel quite a bit, and we'll care about it.

Speaker 1

Do you have a daily review of your dashboard? I don't know.

Jared Palmer

Daily? Daily is slow. Okay.

Speaker 1

I thought you were going to say daily is too much.

Jared Palmer

No, you're thinking it's like every 3 hours—a roll-up of key metrics and stats.

Speaker 1

Yeah.

Jared Palmer

One of them was error-free sessions, and other things like that were really important. Especially now, with agents, which are multi-turn, I have a tweet about this from 2024: agents will really only work when we get not only more intelligent models, but also better reliability from the infrastructure providers.

Inference is not like a database uptime update. There are still differences between providers, differences in performance, and differences in uptime. That's why you see things like OpenRouter being very successful, along with different gateway products.

We would switch because of reliability; they go down all the time. Long story short, it was almost like a video-game style system. We'd have all the data coming in all the time, and that allowed us to do what I used to joke about as mood ranging: good day, bad day.

Speaker 1

So it was very successful for us. I think other teams should adopt that data-driven approach. One thing that's surprising is the relative lack of data-analyst agents, where you can chat with it or add a Slack bot for the precise analytics that you want to generate. I think we're still in the BI era.

Jared Palmer

Yeah. Isn't that weird?

Speaker 1

Yeah, I totally agree. That space hasn't been captured as much. Actually, I'm interested in this shift into knowledge-work tasks with coding agents.

Jared Palmer

Okay. I wonder—

Speaker 1

Using coding agents for non-coding tasks.

Jared Palmer

Correct.

Speaker 1

Do you do that personally?

Jared Palmer

I do. Yeah.

Speaker 1

Yeah? What do you do?

Jared Palmer

This summer, I was helping automate some of my dad's workflows. He's got some Excel spreadsheets for financial accounting, or managerial accounting, I guess. I pointed Claude Code at that stuff to see what happens. It ended up doing Python and generating some scripts. It kind of got off the rails, but even he saw that it was better at it than ChatGPT.

Speaker 1

Super obvious.

Jared Palmer

It became kind of obvious. It felt better.

Speaker 1

I wonder if he can try Claude for Excel and see.

Jared Palmer

Yeah, you got me, right? And then, of course, you've got the browser—the browser-based agents, not computer use, but browsers with agents.

Speaker 1

Agentic browsers, Perplexity, everybody—is that better? If that's true, then maybe the general-purpose injection point is there. Have you tried any of the agent browsers?

Jared Palmer

All of them. I'm currently using Atlas mostly because I just want to give ChatGPT a fair go.

Speaker 1

Okay.

Jared Palmer

But I'm stuck with Arc and its vertical tabs.

Speaker 1

Oh, okay.

Jared Palmer

I think any pro user—I have multiple businesses.

Speaker 1

How many tabs do you—

Jared Palmer

I'm context-switching, right? I have hundreds of tabs open. I made an open-source tool called Chrome Dump. You can find it on my GitHub. It literally dumps all the open tabs, summarizes them, and then I can close them by deleting them in Markdown.

Speaker 1

That's pretty cool. [Laughter.]

Jared Palmer

So you just go on a bender, and then you dump it.

Speaker 1

Yeah. I mean, it should be as easy to close as Markdown in Chrome. Chrome isn't that good on the performance side of things yet.

Jared Palmer

And you were working on some browser comparisons.

Speaker 1

I was, but I tried to build it in Tauri.

Jared Palmer

Okay.

Speaker 1

Tauri explicitly doesn't want you to build a browser, and I tried to fight it too much.

Jared Palmer

I see. Yeah, very cool.

Speaker 1

So, just to wrap things up—we're about out of time—there are other side projects, tasks, and things that you've announced here. First of all, redesigning the GitHub homepage, which a lot of people don't even know GitHub has. [Laughter.]

Jared Palmer

I legitimately want RZ's tweet printed out.

Speaker 1

You read the tweet. There's a tweet like, “No one uses all of this stuff. It's totally useless.” I'll pull it up.

Jared Palmer

I quoted it today because, when we launched—let me get it right, because I've got to do it right. Hold on—it was, “Incredible how pretty much the entire GitHub homepage is useless.” It has 1.3 million views and 19,000 likes, and this was May 22, 2025.

So I heard the team made improvements, and today they launched a new GitHub homepage, which I'm very proud of. They should be really proud of it, too. It's got tasks at the top and recent PRs. Some stuff is still there, like your recent repositories. I still think there's more work to do, but it's really overhauled, and they did an amazing job with it. They nailed it.

There's always more work to do—it's never done—and hopefully we can keep iterating with the community and everyone and keep going.

Speaker 1

The last thing I want to hit you on is stacked diffs.

Jared Palmer

Oh, you asked everyone when you joined what I should work on or something.

Speaker 1

Yeah. What—

Jared Palmer

I don't know if this is your job specifically.

Speaker 1

It wasn't, but why do people want stacked diffs so much? I think you have some history there.

Jared Palmer

Yes. Anyone who's interacted with anyone at Facebook knows about Phabricator, just about it.

Speaker 1

So can you explain why it's been so—what it is and why it's so hard?

Jared Palmer

Okay. So this concept of pull requests, which we're all familiar with: You write some commits, you open a PR, and then you merge the PR and go about your day.

As you scale to larger organizations, you look at your history, and there are people who have near-religious beliefs about how to do Git right: rebase versus merge. There's a crowd that wants to fast-forward the repository to preserve all the history, and then there's a crowd that wants to squash and merge.

Anyway, at Facebook—and I've never worked at Facebook—in my previous startup, Turborepo, I did a lot of research on build systems. Facebook has custom build tools called Buck, a custom file system, and they don't use Git; they use Mercurial, which is now sort of custom, and it's all wired together.

At Facebook, they don't use pull requests. They have a different sort of philosophy. The best way to analogize this is to imagine every PR just had 1 commit in it. You could branch them and restack them, and the critical thing is that you can restack them. If you restack or make a change later—like earlier in the stack rather than later in the stack—and these stacks are just diffs, the commits are just diffs, and that's the term “stacked diffs,” you can then collapse them and merge the last one as a single diff.

It gives you a nicer workflow, and if you work on a monorepo or a very, very large codebase, it's a really nice way to work, especially if you've got a system that will automatically restack. If you think even more deeply about it and get really deep into the weeds, you can decide which diffs in the stack CI should run against, if you get fancy.

Speaker 1

By a commit message or—

Jared Palmer

They're just always there. Yeah, you could decide: Maybe this one doesn't need it, or skip that one, or whatever. You end up getting these groups, these stacks, and it's really nice from a code-review perspective because, when you go to update—or you can update a different part of the stack—it makes it a little more fluid. That's what people want.

There are a couple of tools on the market that do this kind of behavior. One is called Graphite. There are a couple of others.

Speaker 1

Too many tools called Graphite. You see? Here's another Graphite right here.

Jared Palmer

Yeah, yeah. It's a workflow, and so it's been the top pull request—or, sorry, the top feature request—

Speaker 1

Feature request.

Jared Palmer

Feature request, thank you—at GitHub for years, from the community's perspective. I don't know about GitHub, but as soon as I joined, the first thing I did was look this up. I asked how I should make GitHub better, and it was the top feature request.

I went to investigate, like any good product person would, and there have been multiple attempts at this internally going back to 2020. There was one very, very polished attempt in 2022, and I don't have all the context, but there was a pretty good implementation. All of the work was done on the client, and it reintroduced a new concept called stacks outside the pull request into GitHub. It was deemed a little too risky, too big of a change. That's just what I was told.

Anyway, we've had a couple of meetings internally already, and we're trying to weave it into planning and the roadmap. Hopefully we'll be able to share more updates soon, but it's a top-of-the-list known feature.

Speaker 1

Again, heard.

Jared Palmer

Yeah. We're working on it. Obviously, something the size of GitHub moving to support this kind of new feature isn't just a walk in the park because of the size of GitHub and GitHub's Git implementation, but it's something that we're actively exploring.

Speaker 1

Yeah. Well, I think, just to wrap all that up, it's really nice for someone who's so deeply engaged and coming from one of us, literally, that you now run things at GitHub and we can just add you like that.

Jared Palmer

Yeah, yeah.

Speaker 1

That you now run things at GitHub—

Jared Palmer

Yeah. I think Andrej Karpathy was saying the other day that every company needs one of these where you can say, “Hey, this really shouldn't exist at GitHub. We love GitHub, we use GitHub, but come on.”

Feature requests welcome. My DMs are always open.

Speaker 1

Oh, careful.

Jared Palmer

I am of the philosophy that all feedback is a gift. It's all a signal, and the more signal we can collect, the better decisions we can make and the more we can truly build this really useful website and company together. I think that's going to be the future, and if we focus just on that, we're going to be okay.

Speaker 1

Yeah. We're going to be okay. All right, well, thanks so much. Pleasure catching up.

Jared Palmer

Yep, likewise.

Speaker 1

Congrats.
