Claude Sonnet 5 · orcarouter

Claude Sonnet 5 is Anthropic's most capable Sonnet-class model — frontier-level performance across coding, agentic workflows, and professional knowledge work, at a fraction of the cost of the Opus tier. It serves a 1M-token context window with up to 128K output tokens, accepts text, image, and file inputs with text output, and supports adaptive thinking with selectable reasoning effort (low, medium, high, max) so callers can dial the intelligence / latency / cost tradeoff per request. Built as Anthropic's most agentic Sonnet yet, it posts large gains over Sonnet 4.6 on agentic coding and computer-use and closes much of the gap to Opus 4.8 — 63.2% on SWE-bench Pro, 80.4% on Terminal-Bench 2.1, and 81.2% on OSWorld-Verified — while pricing well below Opus 4.8, GPT-5.5, and Gemini 3.1 Pro. It is a strong default for cost-sensitive agents, coding assistants, and high-volume production workloads that still demand frontier reasoning.
