It ships with a 1M token context window and hybrid reasoning, available via anthropic/claude-sonnet-4.6 in the AI SDK.
Anthropic's Claude Sonnet 4.6 is now available on Vercel's AI Gateway, with a 1M token context window. Vercel says the model approaches Opus-level intelligence, with improvements in agentic coding, code review, frontend UI quality, and computer use accuracy.
As a hybrid reasoning model, Sonnet 4.6 delivers both near-instant responses and extended thinking, and can proactively execute tasks, delegate to subagents, and parallelize tool calls, with MCP support for scaled tool use. To use it, developers set anthropic/claude-sonnet-4.6 as the model in the AI SDK, with support for adaptive effort and thinking type parameters.
