Anthropic's New Model Excels at Reasoning and Planning--and Has the Pokémon Skills to Prove It

Anthropic announced two new models, Claude 4 Opus and Claude Sonnet 4, during its first developer conference in San Francisco on Thursday. The pair will be immediately available to paying Claude subscribers. The new models, which jump the naming convention from 3.7 straight to 4, have a number of strengths, including their ability to reason, plan, and remember the context of conversations over extended periods of time, the company says. Claude 4 Opus is also even better at playing Pokémon than its predecessor. "It was able to work agentically on Pokémon for 24 hours," says Anthropic's chief product officer Mike Krieger in an interview with WIRED.
