OpenAI announced GPT-6 with Intelligent UI on October 7. ChatGPT can combine explanations with charts, buttons, forms and interactive tools, such as calculators, directly in a conversation.
The rollout began with Plus, Pro, Business and Enterprise, with Free and Go scheduled to follow on October 8. Enterprise access depends on administrator settings. Paid tiers use GPT-6 Sol, while Free and Go use Luna. This release covers the Chat tab; Work and Codex models are unchanged. Official announcement.
