OpenAI: GPT-6 Sol

GPT-6 Sol is a commercial OpenAI 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 response, which suits long documents, large codebases, or extended multi-file sessions. It supports tool calling and a reasoning mode; the available data does not confirm structured output support, so verify that before relying on it for strict schema work. At $2.00 per million input tokens and $10.00 per million output tokens, it is a paid option where output-heavy workloads will drive most of the cost. Its blended benchmark score of 81.4 rests on a single independent benchmark, so its standing is thinly evidenced and should be treated as provisional. Teams that need very long context alongside tools and reasoning should shortlist it, then validate it on their own tasks against similarly priced alternatives before committing.
