Launched on 5/2/2026, Claude Opus 4.6 is Anthropic's flagship model featuring a 1-million-token context window (beta). Available via claude.ai, Anthropic API, Azure (Microsoft Foundry), or Google Vertex AI at $5/$25 per million tokens. The model is best suited for coding agents (SWE-bench 80.8%), long-horizon agentic tasks, legal and financial analysis, and complex research. Its adaptive thinking feature dynamically adjusts reasoning depth based on task difficulty — recommended for multi-step reasoning prompts. When using the API, enable extended thinking and take advantage of the large context window to ingest entire codebases or long documents in a single query.
