Anthropic: Claude Opus 4.6 · fastrouter

Opus 4.6 is Anthropic’s new top-end Claude model, optimized for complex reasoning, coding, and high‑stakes professional work. It excels at agentic workflows, breaking down multi-step tasks, calling tools, and running for longer with fewer errors and less hand-holding. The model introduces a 1M‑token context window (in beta), stronger long-context retrieval, and up to 128k output tokens for large code and document workloads. It also adds “adaptive thinking” and adjustable effort levels, letting it dynamically choose when to think deeply versus respond quickly.
