Code with Claude Opus 4.6 in Kilo Code
Anthropic's most powerful model for professional software engineering. #1 on agentic coding benchmarks with adaptive thinking and a 1M token context window.
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 — more efficient across the board.
Built for the Entire SDLC
The world's best model for professional software development. Deeper codebase understanding, fewer hallucinations, and stronger architectural reasoning.
Most Agentic Model Yet
Proactively spawns subagents, parallelizes tool calls, and invests more time planning before acting — reducing costly errors on complex tasks.
1M Token Context Window
Analyze entire codebases in a single pass. Understand architectural patterns, dependencies, and implicit conventions across thousands of files.
Complex Bug Hunting
Identifies race conditions, edge cases, and subtle integration issues that other models miss. Perfect for Code Reviewer mode.
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.
