BioCircuit: Prime Intellect builds an RL environment where agents do interpretability research on Qwen3-4B
menhguin · x · 2026-10-13
Researchers in the Prime Intellect Residency program built BioCircuit, an RL environment for training AI agents to do auto-research — with mechanistic interpretability as the subject.
- Agents trace attribution graphs on Qwen3-4B and identify the features behind a concept
- Grading works by having agents intervene on prompts they've never seen, validating their discovered features
- The authors argue auto-research needs dedicated training environments, and interpretability is an ideal fit
A detailed blog post accompanies the release.
