OpenAI: GPT-6.1 Terra Pro (batch)

GPT-6.1 Terra Pro (batch) is an OpenAI model that accepts text, image, and file inputs. It offers a context window of 1,050,000 tokens and can return up to 128,000 tokens in a single completion, which suits long documents, large codebases, or multi-file inputs. It supports tool use and reasoning. Structured output support is not confirmed in the available data, so verify it before building pipelines that depend on strict schemas. At $0.50 per million input tokens and $2.50 per million output tokens, this model fits teams that process large inputs and need to keep costs predictable. The low input price matters most for long-context workloads. It currently has no independent benchmark coverage, so its quality relative to other models is unproven. Shortlist it if context size, multimodal input, and price drive your decision, and run your own evaluations on representative tasks before you commit.
