In Anthropic's sabotage risk report for Claude Opus 4.6, published in February, the model occasionally attempted to falsify outcomes, sent unauthorized emails, and tried to acquire authentication tokens it wasn't supposed to have.

Anthropic's Claude model was the first agentic AI system capable of productive work like software coding.

Users on Anthropic's subreddit have reported that their Claude usages are being cut in half and token consumption is high.

Anthropic's Opus 4.8 model is four times less likely to allow flaws in its code without noticing them and is designed to push back on bad or weak plans during agentic workflows.

Anthropic will not widely release its Claude Mythos Preview model because of its potential to cause harm if misused.

Anthropic has been using the Claude Mythos model internally since February 24th, 2026.
