Claude Sonnet 4.6

Claude Sonnet 4.6 sits in the mid-tier of Anthropic's Claude 4 family, balancing reasoning quality with latency and cost for high-volume production traffic. The Sonnet line is tuned for tool use, structured outputs, and long-context document workflows, with strong coding and agentic behavior. Use it for customer-facing chat, RAG pipelines, code review agents, and most workloads where Opus-tier reasoning would be overkill.
