Claude Opus 4.6
Claude Opus 4.6 is the first Opus model with a context window of 1M tokens, introduces adaptive thinking for model-decided reasoning depth, supports interleaved thinking and tool calls in a single response, and delivers equal or better performance than fixed extended thinking across programming, analysis, and creative tasks.

Copy link to headingAbout Claude Opus 4.6
Claude Opus 4.6 launched on AI Gateway on February 5, 2026, bringing two advances to the Opus tier. First, the context window of 1M tokens. This is the first time an Opus model supports this context size, matching what Sonnet 4.5 gained. For teams needing both Opus-level intelligence and large context capacity, this closes a capability gap.
Second, adaptive thinking: a new thinking type parameter (set as thinking: { type: 'adaptive' }) that lets the model decide when and how much to reason, rather than requiring you to specify a fixed thinking budget. Claude Opus 4.6 also supports interleaved thinking and tool calls within a single response. The model can reason, call a tool, reason further about the result, and call another tool, all in one response rather than requiring separate turns. This applies to complex agentic workflows where the best next tool call depends on reasoning about previous results.
Anthropic described Claude Opus 4.6 as built to power agents that handle real-world work, with strength across the development lifecycle. To use Claude Opus 4.6, set the model to anthropic/claude-opus-4.6 in the AI SDK, Chat Completions API, Responses API, Messages API, or other API formats, from TypeScript or Python. When using the AI SDK, configure providerOptions.anthropic with the thinking and effort parameters as needed.
Copy link to headingWhat To Consider When Choosing a Provider
- Configuration: Requests using the context window of 1M tokens generate higher per-request token volumes than typical API calls. AI Gateway cost tracking per request is useful for budgeting large-context workloads.
- Zero Data Retention: Zero Data Retention is available for this model. It is offered on a per-provider and model basis. See the documentation for details.
- Authentication: AI Gateway authenticates requests using an API key or OIDC token. You do not need to manage provider credentials directly.
Copy link to headingWhen to Use Claude Opus 4.6
Best for
- Opus intelligence at large context: Entire large codebases, extensive document sets, or long conversation histories where prior Opus models hit context limits
- Interleaved reasoning and tool use: Complex multi-step pipelines where reasoning about tool results before the next call improves outcomes
- Adaptive thinking efficiency: Letting the model calibrate its own reasoning depth avoids over-spending thinking tokens on simpler requests in mixed workloads
- Programming, analysis, and creative tasks: At Opus depth, Claude Opus 4.6 excels across all three categories
- Development lifecycle agents: The announced strength area for this checkpoint
Consider alternatives when
- Primary cost constraint: Sonnet 4.6 approaches Opus-level intelligence at lower cost per token
- Smaller context sufficient: Earlier Opus versions handle workloads that don't need the context window of 1M tokens
- Maximum speed required: Sonnet and Haiku variants serve latency-sensitive use cases better
Copy link to headingConclusion
Claude Opus 4.6 closes the context window gap between the Opus and Sonnet tiers while introducing adaptive thinking, a more efficient approach to reasoning that performs on par with or better than fixed thinking budgets. For teams that need Opus-level intelligence at large context scale, this is the model.
