Summary

Monthly Circuits Updates dispatch from September 2024 — preliminary experiments and developing ideas from Anthropic’s interpretability team. Full content at transformer-circuits.pub (access restricted). Framed as lab meeting notes rather than mature research, covering ideas likely to appear in future full papers.

Implications

Part of the mechanistic interpretability cadence. September 2024 falls in the period between the open-sourcing of circuit tracing tools (May 2025) and the engineering challenges of scaling interpretability paper (June 2024), placing this in the active scaling phase of the SAE program. Watch against subsequent full papers to see which threads from this period solidified into publishable results.
