OpenAI: GPT-6.1 Sol

OpenAI's GPT-6.1 Sol is a proprietary-listed, paid model that accepts text, image, and file inputs and returns text. It offers a context window of 1,050,000 tokens and can generate up to 128,000 tokens in a single completion, which suits long documents, large codebases, or multi-file inputs. It supports tool calling and reasoning. The listing does not specify structured output support or whether weights are open, so teams that depend on schema-constrained responses should verify that separately. Pricing is $2.00 per million input tokens and $10.00 per million output tokens, so output-heavy workloads will cost noticeably more than input-heavy ones. Its blended benchmark score of 89.2 rests on a single independent benchmark (AI Index score 85.5), which is a narrow basis for ranking. GPT-6.1 Sol belongs on the shortlist for long-context, tool-using work with mixed file and image inputs, but buyers should run their own evaluations before committing.
