Anthropic rolls out Opus 5 AI model in efficiency upgrade

“We’re building and continue to consistently deliver frontier intelligence and bring that as accessibly as possible with every model generation,” said Penn.

 

In testing, Opus 5 was less capable of exploiting cyber vulnerabilities than Anthropic’s top-shelf AI, so its ‌related ⁠safeguards are less restrictive than Fable 5’s. Opus 5 was also less susceptible to being tricked into misuse than Anthropic’s other current models, the startup said.

 

Released in June, Anthropic’s Fable 5 was temporarily unavailable following U.S. concerns that its capabilities ⁠could be diverted to foreign military intelligence.
