Anthropic: Claude Opus 5.5 (batch)

Anthropic's Claude Opus 5.5 (batch) is a paid model that accepts text, image, and file inputs. It offers a 1,000,000-token context window and can return up to 128,000 tokens in a single completion, which suits long documents and lengthy generated outputs. It supports tool use and reasoning. The listing does not confirm structured output support, so buyers who need it should test before committing. Pricing is $2.00 per million input tokens and $10.00 per million output tokens. Output costs five times as much as input, so the model is most economical for input-heavy work such as long-context analysis. It posts a blended benchmark score of 100.0 and an AI Index score of 95.1. That standing rests on a single independent benchmark, however, so treat it as a promising signal rather than proof. Teams that need large context, multimodal input, and tools should shortlist this model and validate it on their own tasks.
