AI Startup Anthropic Releases More Powerful Opus Model After Delay

Anthropic is set to roll out two new versions of its Claude artificial intelligence software, including a long-delayed update to its high-end Opus model, as the startup vies to stay ahead of a crowded market.

The company on Thursday plans to unveil Sonnet 4 and Opus 4, the latter of which is billed as Anthropic’s most powerful AI system yet. Both models are designed to better follow directions and operate more autonomously when fielding tasks such as writing code and answering complicated questions.
