Anthropic: Claude Opus 4.1

Claude Opus 4.1 is a paid model from Anthropic that accepts text, images, and file uploads, with a 200,000-token context window and a 32,000-token output cap. It supports tool use and reasoning, which makes it suitable for multi-step tasks and agentic workflows. Structured output support is not confirmed in available specifications. 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, so cost-sensitive users should weigh that carefully. Its blended benchmark score of 55.5 is drawn from a single benchmark source, which limits how confidently that number generalizes across task types. Teams running long-context document work, tool-augmented pipelines, or reasoning-heavy applications may find it worth shortlisting, but those primarily optimizing for price-to-performance should compare it against lower-cost alternatives before committing.
