gpt-6.1

GPT-6.1 most likely refers to OpenAI’s GPT-6.1 model family, especially GPT-6.1 Sol and GPT-6.1 Terra; sources describe Sol as a lower-cost, near-Astra model for coding, computer use, and professional work.[1][4] Some third-party and official pages also mention Luna as part of a broader GPT-6/6.1 lineup, but the provided results do not establish a separate public launch page for “gpt-6.1” alone.[26]

OpenAI’s pages say GPT-6.1 Sol is “the latest model family in the GPT-6 series” and that it delivers near-Astra performance at lower cost, with availability in ChatGPT Work, Codex, and the API.[1][4][3] The results also show GPT-6.1 Terra as a separate release focused on visual reasoning, computer use, and writing, but they do not clearly confirm what “gpt-6.1” means beyond this family naming or whether “luna” is a public model name rather than a cloud-availability reference.[17][26]
