GPT-6 with Intelligent UI for ChatGPT Users
GPT-6 with Intelligent UI changes the ChatGPT experience by allowing responses to include graphics, tappable buttons, forms, charts and interactive tools. These elements can make a task easier to understand or complete than a plain text reply.
ChatGPT can also build small task-specific tools inside a conversation, with interfaces appearing progressively as the response is generated. This is useful for planning, calculations, visual explanations and other tasks where an interactive response is more convenient.
OpenAI says the rollout started for ChatGPT Plus, Pro, Business and Enterprise on October 7, with Free and Go starting from October 8. Enterprise access can depend on workplace administrator settings, so availability may vary between organisations.
OpenAI’s Intelligent UI details explain how these interactive elements are designed to appear within ChatGPT responses.
