Anthropic launched two new models, Claude Fable 5.2 and Claude Mythos 5.2, on November 9, 2026. The company says they are designed for demanding technical work and show improvements in coding, reasoning and vision. Anthropic says the models generate outputs faster than the 5.1 versions and can orchestrate agent teams on long-running projects. TechCrunch reported that the company frames the release around communicating more clearly with users, amid ongoing concerns about recursive self-improvement.
