Sonnet 4.6 comes less than two weeks after Opus 4.6, and performs almost as well at the same old cost of $3/$15 per million tokens.

It features upgrades across coding, computer use, long context reasoning, agent planning, knowledge work and design, Anthropic says.

It is now the default model for the Free and Pro plans, and has a context window of 1 million tokens.

The model performs best in class for Agentic financial analysis and Office tasks on benchmarks, but it otherwise lags slightly behind Opus 4.6.

— Sonnet 4.6 offers strong performance at any thinking effort, even with extended thinking off, Anthropic writes.

Also, Claude in Excel now supports MCP connectors, so you can now import data and use everyday tools without ever leaving Excel.
