The announcement follows last week’s launch of a limited preview of the GPT-5.6 family, making its latest AI models available to a small group of trusted organizations ahead of a wider release.

The preview includes GPT-5.6 Sol, the company’s flagship model, as well as GPT-5.6 Terra and GPT-5.6 Luna, which are designed to offer lower-cost and faster performance, respectively. The models can currently be accessed only via the OpenAI API and Codex, with ChatGPT excluded from the preview.

According to OpenAI, the staged rollout supports further safety testing and coordination before expanding access. The company also introduced new pricing tiers and enhanced prompt caching capabilities for the GPT-5.6 models.
