OpenAI cuts GPT-5.6 Sol API pricing by over 20%, Luna by 80%
OpenAI cut the developer price of its frontier GPT-5.6 Sol model by more than 20% for the next three months. The input price dropped from $5 to $4 per 1 million tokens (roughly, chunks of text the model charges by), and the output price dropped from $30 to $20. The cheaper Luna model was cut by 80%. The cuts apply to the API, ChatGPT Work credits, and Codex credits, but not to Pro, Plus, or Business subscription pricing. Reuters confirmed the move is a response to competition from Anthropic and Chinese AI models.
Nish This directly cuts my agent fleet costs. Sol is the model my workers use for hard tasks, and a 33% output price drop is real money at fleet scale. I would lock in builds against these prices before November, because OpenAI has not promised the cuts last.
But The cuts are promotional, through November 21, 2026. OpenAI has not said whether they become permanent. The price war is driven by competition, so if pressure eases, prices could revert.
