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.

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. Another reason Anthropic thinks Opus 4 is ready to enable the creation of better AI agents is because the model is 65 percent less likely to use a shortcut or loophole when completing tasks. Like Claude 3.7 Sonnet before it and Opus 4, the new system is a hybrid reasoning model, meaning it can execute prompts nearly instantaneously and engage in extended thinking.
