Anthropic: Claude Sonnet 5
Analysis Summary
Claude Sonnet 5 is Anthropic's latest Sonnet-family flagship, released June 2026. With an intelligence index of 53.4 and a coding index of 71.5, it sits at the very top of the field, just behind Claude Opus 4.8 and GPT-5.5. It supports vision, tool use, function calling, and a 1M token context window, giving it exceptional breadth for a single model deployment.
For businesses, this combination makes it a strong fit for autonomous coding agents, long-document analysis, customer-facing content pipelines, and multimodal workflows. The 1M context window is a genuine operational advantage for teams working with large codebases, contracts, or research corpora. Instruction following and long-context reliability scores are both high, supporting reliable client-facing output.
At $2 per million input tokens and $10 output, it is priced competitively for a model at this capability level. Teams that currently use Claude Sonnet 4.6 should upgrade; those running GPT-5.4 or Gemini 3.1 Pro should evaluate it directly against their workloads.
