Why developers choose Opus 4.6
The most powerful model for complex, long-running professional tasks
Adaptive Thinking
Dynamically allocates cognitive effort based on problem complexity. Fast on simple queries, deeply analytical on hard problems.
Built for the Entire SDLC
Deeper codebase understanding, fewer hallucinations, and stronger architectural reasoning across your entire development lifecycle.
Most Agentic Model Yet
Proactively spawns subagents, parallelizes tool calls, and invests more time planning before acting — reducing costly errors.
1M Token Context Window
Analyze entire codebases in a single pass. Understand architectural patterns, dependencies, and conventions across thousands of files.
Complex Bug Hunting
Identifies race conditions, edge cases, and subtle integration issues that other models miss.
Benchmark Leader
65.4% Terminal-Bench 2.0, 72.7% OSWorld, 84.0% BrowseComp, 68.8% ARC AGI 2 — #1 across virtually every agentic benchmark.
