Anthropic’s Claude Opus 4 model can work autonomously for nearly a full workday

Anthropic kicked off its first-ever Code with Claude conference today with the announcement of a new frontier AI system. The company is calling Claude Opus 4 the best coding model in the world. According to Anthropic, Opus 4 is dramatically better at tasks that require it to complete thousands of separate steps, giving it the ability to work continuously for several hours in one go. Additionally, the new model can use multiple software tools in parallel, and it's better at following instructions more precisely.

In combination, Anthropic says those capabilities make Opus 4 ideal for powering upcoming AI agents. For the unfamiliar, agentic systems are AIs that are designed to plan and carry out complicated tasks without human supervision. They represent an important step towards the promise of artificial general intelligence (AGI). In customer testing, Anthropic saw Opus 4 work on its own seven hours, or nearly a ...
