Anthropic said Monday its latest model — Claude 3.7 Sonnet — integrates advanced reasoning capabilities for the first time.

Why it matters: While OpenAI and others have released separate models focused on longer reasoning times, Anthropic adds advanced reasoning into standard models.

How it works: Anthropic says the new model is capable of near-instant responses or extended responses that show step-by-step reasoning with users able to choose which type of response they're looking for.

Anthropic's API users can control how long Claude spends reasoning before answering. That's important because longer reasoning time increases the cost of a query.
Claude 3.7 Sonnet also has enhanced computer use abilities and improved coding skills.
Anthropic said the new model will be available on all its Claude.ai plans, via its API and through cloud providers Google and Amazon.
