Anthropic Releases Claude 4 with Extended Thinking Mode

Anthropic has launched Claude 4, introducing a new extended thinking mode that allows the AI to reason through complex problems before generating a final response. This approach mirrors the chain-of-thought techniques seen in OpenAI's o-series models.

The model shows particular strength in coding, mathematics, and nuanced reasoning tasks. Anthropic claims Claude 4 sets new standards for AI safety while delivering state-of-the-art performance.
