Sept. 29 (UPI) -- Anthropic on Monday unveiled its latest artificial intelligence model, called Claude Sonnet 4.5, which the tech company called "the best coding model in the world."

That AI boast is based on industry benchmarks, including software engineer bench tests that measure an AI system's software coding abilities, the company said in a news release. That includes following instructions more reliably, the company said.

It can operate 30 hours by itself.

"People are just noticing with this model, because it's just smarter and more of a colleague, that it's kind of fun to work with it when encountering problems and fixing them," Jared Kaplan, Anthropic's co-founder and chief science officer, told CNBC in an interview.
