Don't Fight Backprop: Goodfire's Vision for Intentional Design, w/ Dan Balsam & Tom McGrath
Erik TorenbergNathan LabenzDan BalsamTom McGrath
Goodfire’s $150 million Series B at a $1.25 billion valuation turns its interpretability research into an execution test spanning seven-figure engagements and a scalable AI stack.Its hallucination experiment used a frozen reward model to improve behavior without obvious capability loss, but robustness remains conditional on probe quality, training configuration, and scale.
Mechanistic Interpretability: Philosophy, Practice & Progress with Goodfire's Daniel & Tom
Mechanistic interpretability now has the raw materials of a “proto-paradigm”: understandable features, linear directions, superposition, and circuits, despite lacking consensus.Existing tools already help customers, with scientific discovery and inference-time guardrails emerging as important applications while algorithms remain the softer bottleneck.Yet a scaling study found reconstruction curves bending before 99.99% or 100%, leaving memorization, higher-order geometry, or noise unresolved as Goodfire advances its $50 million independent category bet.
