Anthropic has launched Mythos 5.2 and Fable 5.2 with improvements in coding, reasoning and speed. The release comes amid concerns about recursive self-improvement, covert capabilities and increasingly difficult safety evaluations.

Anthropic today introduced its latest models, Claude Fable 5.2 and Claude Mythos 5.2, which have improvements in coding, reasoning, and vision. Anthropic says Fable 5.2 and Mythos 5.2 communicate more clearly than the 5.1 versions, with outputs generated up to 30 percent faster. Fable 5.2 uses fewer tokens than Fable 5.1 on challenging tasks when set to medium effort. The company suggests using Fable and Mythos for "the most ambitious, open-ended technical work".
