Anthropic releases Opus 5 with ‘close’ to Fable 5’s

What happened

Weeks after Anthropic’s latest toe-to-toe with the US government, and days after an OpenAI security incident that dominated tech industry discussions, Anthropic on Thursday released its newest model, Claude Opus 5. The company said in a release that Opus 5 “comes close to the capabilities of Claude Fable 5 in many domains” and is much better at complex coding tasks.

Why it matters

When asked whether Anthropic ran Opus 5 by the Trump administration before this public rollout, Anthropic spokesperson Danielle Ghiglieri told The Verge, “We continue to work with our government partners to conduct their own independent testing of our models.

” Anthropic is marketing Opus 5 especially to its enterprise customers, saying it’s best for knowledge work and biology and that it’s the ideal everyday model, with Fable 5 still being best for the most ambitious types of work and long-horizon AI agent projects.

” With the new model’s release, the company also seems to subtly address recent controversies over allegedly hidden usage caps — which have led to at least one lawsuit — and the AI money squeeze, or concerns that AI labs’ costs are being passed onto their customers in new ways.

What to watch

Per million tokens, pricing for Opus 5 is the same as its predecessor ($5 input / $25 output), and Anthropic made the point that it’s “half the price” of Fable 5. 6. Customers can also choose “Fast mode” for Opus 5 (a feature that’s being launched today in research preview), to get higher speeds for double the price.

There’s also an option to opt in to automatic fallbacks to a lower-tier model when safeguards mandate that Opus 5 declines a user’s request. Follow topics and authors from this story to see more like this in your personalized homepage feed and to receive email updates.
