Anthropic: Claude Opus 5.5 (batch)

Claude Opus 5.5 (batch) is an Anthropic model offered through a batch endpoint. It accepts text, image, and file inputs, and it supports a context window of 1,000,000 tokens with up to 128,000 completion tokens per response. Tool use and reasoning are both supported. The listing does not say whether structured output is available, so teams that depend on enforced schemas should confirm this before committing. At $2.00 per million input tokens and $10.00 per million output tokens, the batch variant suits workloads that can tolerate deferred processing. Long-document analysis, bulk file review, and multi-step tool workflows are good fits, since large inputs and lengthy outputs are both accommodated. Its performance is unproven for now. It has no independent benchmark coverage, so buyers cannot compare it against alternatives on measured results. Shortlist it on the strength of its context size and pricing, then validate quality with your own evaluation set before scaling up.
