How modern AI actually works - Mechanistic Interpretability, the systems builders ship, and a weekly signal on what matters.
Free · the weekly Signal + new explainers · no noise
Inside the black box.
A working community for builders untangling how AI actually works - interpretability, agents, MCP, safety, and what shipped this week. Specific questions, real answers.
Everything else, in one place.
The forum is the heart of it. These are the surfaces that feed it - the explainers, the weekly signal, and the tools you wire in.
From black box to clear mental model.
Hand-crafted explainers - what mech interp is, how LLMs work, and how models become software that acts.
Keep up without drowning.
New models, tools, MCPs, and research - each with a one-line take on whether it matters or it's hype.
The new tools - and what they can touch.
MCP servers, dev workflows, RAG stacks, and evals - each with a threat model attached.
Understand AI before it runs everything.
One email a week: the new explainers, the tools worth trying, and the research that actually matters. Free, no noise.
