Claude Opus 4.6 now available on AI Gateway
Anthropic's Claude Opus 4.6 model is now available on Vercel's AI Gateway with support for 1M token context window and adaptive thinking that lets the model decide when to reason for more efficient responses. Users can access the model by setting the model parameter to anthropic/claude-opus-4.6 with optional effort configuration.
Anthropic's latest flagship model, Claude Opus 4.6, is now available on AI Gateway. Built to power agents that handle real-world work, Opus 4.6 excels across the entire development lifecycle. Opus 4.6 is also the first Opus model to support the extended 1M token context window.
The model introduces adaptive thinking, a new parameter that lets the model decide when and how much to reason. This approach enables more efficient responses while maintaining quality across programming, analysis, and creative tasks, delivering equal/better performance than extended thinking. Opus 4.6 can interleave thinking and tool calls within a single response.
