Anthropic traces planning, hidden goals and jailbreak circuits in Claude 3.5 Haiku

Anthropic's circuit-tracing work found forward planning, multilingual abstractions, fabricated reasoning, jailbreak dynamics and a controlled hidden-goal mechanism inside Claude 3.5 Haiku. The team later released the tracing tools for open-weight models and an interactive public interface.

Why it moved the index

The research exposed alignment-relevant mechanisms in a production model, tested causal interventions and was followed by a dated release of open-source circuit-tracing tooling. The authors state that useful explanations covered only about one quarter of attempted prompts, limiting assurance.
