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.

Gemini 4 Argon is Google's flagship reasoning model for software engineering, math and science problem-solving, and multi-step agent workflows, with output of up to 1M tokens versus 64K for earlier Gemini models. Google reports it beating GPT-6 Astra and Claude Opus 5.5 on 12 of 18 published benchmarks, though those results are company-reported.
