Anthropic: Claude Opus 4.1

Claude Opus 4.1 is Anthropic's paid text and vision model, accepting image, text, and file inputs across a 200,000-token context window. It supports tool use and reasoning, giving it a workable foundation for multi-step or agentic tasks. Structured output support is unconfirmed from available data, so workflows that depend on guaranteed JSON schemas should be tested carefully before committing. At $15.00 per million input tokens and $75.00 per million output tokens, this is one of the more expensive options on the market, and its blended benchmark score of 55.5 across a single independent benchmark leaves its performance standing difficult to assess with confidence. Buyers who have already validated Anthropic's outputs on their specific workloads, and who need long context or file handling, are the most plausible fit; cost-sensitive teams or those wanting broad third-party benchmark coverage should compare alternatives before deciding.
