Claude launches smarter Sonnet 5 model

Claude Sonnet 5 is built to be the most agentic Sonnet model yet. It can make plans, use tools like browsers and terminals, and run autonomously at a level that, just a few months ago, required larger and more expensive models.

For many developers, the agentic AI era began with Sonnet-class models: Claude Sonnet 3.5, 3.6, and 3.7 were the first models that showed impressive skills in coding and tool use.

This new version is almost as smart as their most powerful model, Opus 4.8, but costs less to use.

Smart media selection: Intelligently chooses between images, videos, or both based on query type Configurable control: Enable/disable and override media types as needed New max_tokens parameter: Control the maximum tokens extracted per page in search results. This gives you finer control over response size and costs.
