OpenAI launches GPT-6 Sol and Luna, boasting lower cost and fewer mistakes

OpenAI has reportedly introduced GPT-6 Sol and GPT-6 Luna, two models described as sharing the same underlying approach as Astra. The practical pitch is lower operating cost and fewer errors, which could make them relevant for production workloads where inference spend and reliability matter more than headline capability. The available report does not provide benchmark results, pricing, context-window limits, API availability, or a clear breakdown of how Sol and Luna differ. Builders should therefore treat the cost and accuracy claims as unverified until OpenAI publishes model cards, evaluations, and deployment details.
