GPT‑6 in ChatGPT introduces Intelligent UI, a new capability that allows ChatGPT to answer quickly with fully interactive user interfaces that make everyday answers more visual, make learning complex topics easier and that can quickly create a tool to solve a task right in the moment.
GPT‑6 with Intelligent UI is rolled out globally to ChatGPT Plus, Pro, Business and Enterprise tiers in the Chat tab. Starting today, the rollout expands to Free and Go tiers. Enterprise availability depends on workplace admin settings.
GPT‑6 in ChatGPT is powered by GPT‑6 Sol for Plus, Pro, Business, and Enterprise tiers, and GPT‑6 Luna for Free and Go tiers. Both are tuned for everyday conversation.
This update applies to the Chat experience in ChatGPT. The models powering Work and Codex are not changing as part of this release.
