OpenAI releases GPT-6.1 Sol at lower listed API prices

OpenAI released GPT-6.1 Sol across ChatGPT Work, Codex and the API, and says it approaches GPT-6 Astra on selected reasoning and agent tasks at lower listed input and output prices. The announcement reports vendor evaluations and availability details, but it does not independently establish production performance or broad user adoption, and the model was not yet in standard ChatGPT at publication.
