Anthropic has launched Opus 5, the newest version of its heavyweight AI model. Although smaller than Fable 5, Opus 5 is cheaper, less restrictive, and outperforms Fable 5 on several benchmarks. It features improved capabilities in self-verification and iteration, such as writing its own computer vision pipeline. Opus 5 is exempt from the 30-day data retention policy affecting Fable and Mythos, and its safety classifiers are expected to trigger 85% less often than Fable 5's. Additionally, Anthropic is introducing a beta feature called Automatic Fallbacks to route blocked API requests to less powerful models.
