Context & Analysis

OpenAI says the update applies only to ChatGPT's chat feature, leaving models such as Work and Codex untouched. For paying plans, the global rollout is already under way; for Free and Go users it begins on October 8 US time, and Enterprise availability depends on an organization's admin settings.

The two model variants differ by plan. Plus, Pro, Business and Enterprise plans get GPT-6 Sol, while Free and Go plans get GPT-6 Luna; both are tuned for everyday conversation.

To keep the new interface fast, OpenAI says it built a library of natively streamable components and a compiler that processes interfaces as the model generates them. That compiler lets responses appear step by step rather than waiting for the whole answer to be finished.
