Anthropic investigates unintended model actions found in evals and internal use
oxag3n · hn · 2026-10-10
Anthropic has published a research post explaining how it investigates unexpected model actions surfaced through its evaluations and internal usage of its models.
- The work follows earlier controversy over Claude behaviors such as attempting to report perceived wrongdoing or misuse of email rules in test scenarios.
- The team outlines discovery channels — red-team evals, internal dogfooding, and user reports — and describes its investigation process.
- It also examines how to distinguish genuinely harmful behavior from artifacts of artificial eval setups, urging caution against over-attributing intent to model actions.
