Claude Opus 5.5 is Anthropic's flagship model released September 22, 2026 as the first of the Claude 5.5 family, with a 1M-token context window, text, image, and file input, and pricing of $4/$20 per million input/output tokens. Anthropic says it performs at the level of Claude Fable 5.1 on most work while costing about 40% less to run than Opus 5, and it leads on agentic coding, multi-step changes in large codebases, and long-horizon knowledge work.
Claude Sonnet 5.5 is Anthropic's Sonnet-class model (1M-token context, 128K max output, $2/$10 per million input/output tokens), released September 28, 2026 as a direct upgrade to Sonnet 5 and a faster, lower-cost complement to Opus 5.5. It generates output over 30% faster with fewer tokens per task, and is strongest at well-scoped everyday work such as building features, fixing bugs, and producing polished documents, slides, and spreadsheets.
