Anthropic's new AI model rivals Fable 5 and is cheaper as businesses fret about costs
Anthropic on Friday announced its latest artificial intelligence model, Claude Opus 5, which it said is its best-performing and most cost-effective offering across a number of industry benchmarks. Opus 5 outperforms the last model that Anthropic released, Claude Fable 5, on coding and knowledge work evaluations, and the company said it's "designed to be used every day," according to a blog post. "If it's a cheaper model or a cheaper offering, but it's not accomplishing a similar level of quality, it's actually not useful."
