OpenAI expands GPT-6 access and introduces interactive ChatGPT responses
OpenAI announced wider access to GPT-6 and a new Intelligent UI capability for ChatGPT. Free and Go users are set to receive GPT-6 Luna from October 8, following the initial rollout to paid customers last month. Intelligent UI lets ChatGPT respond with interactive interfaces, including charts, buttons and input forms. OpenAI says more than 1.2 billion people use ChatGPT weekly.
Key points
- GPT-6 Luna access starts October 8 for free and Go users; paid users receive GPT-6 Sol from October 7.
- Intelligent UI enables interactive ChatGPT responses with charts, buttons, input forms and tools such as calculators.
- Intelligent UI applies to ordinary chats, not business-specific features or Codex.
- OpenAI says more than 1.2 billion people use ChatGPT weekly.
- Usage limits, regional availability and detailed differences between Sol and Luna were not reported.
What happened: OpenAI is expanding access to GPT-6, the AI model family behind its latest ChatGPT update, and introducing responses that users can interact with rather than simply read. KBS reported that OpenAI announced the expansion on October 7, following the first GPT-6 rollout to paid customers the previous month. Paid users gain access to GPT-6 Sol from October 7, while free users and subscribers to the lower-cost Go plan are set to receive GPT-6 Luna from October 8. OpenAI says more than 1.2 billion people use ChatGPT weekly.
The details: The main interface change is Intelligent UI, which lets ChatGPT answer questions with charts, diagrams, buttons and input forms instead of text alone. According to KBS, users can also ask ChatGPT to create tools on the spot, including savings calculators, expense-splitting calculators and simple games. The change does not mean every answer becomes an interactive screen. ChatGPT will continue to respond in writing when plain text is more appropriate for the question.
Who it affects: For business teams evaluating ChatGPT, the access expansion means GPT-6 Luna will be available without a higher-priced subscription. That broadens the opportunity to try the model, but the interface rollout has an important boundary: KBS reported that Intelligent UI applies to ordinary conversations, not business-specific features or OpenAI’s Codex coding tool. The distinction matters when assessing the announcement. Interactive responses in a regular chat are not the same as an announced capability across workplace and coding products.
Background: The announcement comes alongside a competing release from Anthropic. KBS reported that Anthropic launched Claude Haiku 5.5 on the same day, targeting repetitive, high-volume tasks such as summarization, classification and database queries. Anthropic said its running costs average about 75% below those of Haiku 4.5. It also claimed that Haiku 5.5 outperformed GPT-6 Luna in its own evaluations of areas including computer use and agent coding. Those results were company claims, rather than independently verified comparisons in KBS’s report.
What to watch: The immediate questions for teams are how the two GPT-6 versions differ and what restrictions apply to access. Detailed capability differences between Sol and Luna, usage limits, and regional availability were not reported. Nor were details about whether the interactive tools can be saved or shared. For now, the announced changes establish broader model access and a new way to interact with ChatGPT, but not the full conditions for using those capabilities in repeatable team workflows.
Our take
Broader access makes GPT-6 easier for teams to evaluate, while interactive responses could change how they build and share ChatGPT workflows.
