Anthropic: Claude Opus 5 (batch)

Anthropic: Claude Opus 5 (batch) is a proprietary-access model from Anthropic 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 large multi-file inputs. The model supports tool use and reasoning. The listing does not specify structured output support, so teams that depend on strict schema adherence should verify that behavior before committing. Pricing is $2.50 per million input tokens and $12.50 per million output tokens, so output-heavy workloads will drive most of the cost. Its blended benchmark score is 87.3, with an AI Index score of 83.8, but that figure rests on a single independent benchmark. The standing is promising yet thinly evidenced. Shortlist it if you need very long context, mixed inputs, and tool-driven workflows, and run your own evaluations alongside it before choosing.
