Weeks after Anthropic’s most recent face-to-face meeting with the US government, and days after OpenAI Security incident Dominating tech industry discussions, Anthropic on Thursday released its latest model, the Claude Opus 5.
The company said in a statement that Opus 5 “comes close to the capabilities of Claude Fable 5 in many areas” and is much better at complex programming tasks. (Tale 5 is a public-facing Mythos class model that has drawn the wrath of the government Taken offline For a few weeks with Mythos 5, and then He repeated With stronger cyber safeguards than before.)
The Myth 5 scare — and the ensuing weeks of negotiations between Anthropic and the government — launched a new era of AI regulation for the Trump administration. Shortly after, when OpenAI has released GPT-5.6it has undergone a trial period of approximately two weeks, and has been released in limited preview only to government-approved entities.
Anthropic promises stronger cybersecurity guarantees with Opus 5
When asked whether Opus 5 was run by the Trump administration prior to this public offering, Anthropic spokeswoman Danielle Giglieri said: Edge“We continue to work with our government partners to conduct their independent testing of our models. This includes Opus 5.”
Anthropic is marketing Opus 5 specifically to its enterprise clients, saying it’s best for cognitive and biology work and that it’s the ideal everyday model, with Fable 5 continuing to be best for more ambitious types of work and longer-term AI client projects. But the company was keen to say in a statement that it has stronger cybersecurity safeguards than its predecessor, Opus 4.8, and that it is “the most compatible Opus model and least susceptible to phishing and abuse.”
With the release of the new model, the company also appears to be subtly addressing recent controversies over alleged hidden usage limits — which have led to… At least one lawsuit — and AI money squeezeor fears that AI labs will transfer costs to their clients in new ways. Per million tokens, Opus 5’s price is the same as its predecessor ($5 in/$25 out), and Anthropic noted it’s “half the price” of Fable 5. It’s also A little cheaper From OpenAI GPT-5.6.
Customers can also opt for Opus 5’s “Fast Mode” (a feature launching today in search preview), to get faster speeds for double the price. There is also the option to opt in to automatic fallbacks for the lower tier model when safeguards force Opus 5 to reject a user request.
