OpenAI unveils gpt-6 with enhanced interactive chat interface

OpenAI announced the release of GPT-6 on October 8, 2026, introducing a new interactive Smart UI for ChatGPT users. This update replaces previous versions, GPT-5.6 Sol and GPT-5.6 Luna, and focuses on improving the user experience through dynamic content presentation. The Smart UI allows AI to deliver answers in formats such as images, charts, and operable interfaces directly within the chat window, enhancing interactivity. The upgrade is rolled out in phases, with Pro, Business, and Enterprise users already receiving the update, while free and Go users will follow later. GPT-6 Sol is available to paying users, while GPT-6 Luna is tailored for free and Go users, both optimized for daily conversation. OpenAI emphasized that Smart UI does not always activate, ensuring text-based responses for simple queries to avoid unnecessary complexity. Performance improvements include faster response times, with GPT-6 Instant reducing the average waiting time for online searches by 44% compared to GPT-5.6 Instant. Additionally, the model's foundation has been enhanced with better online search quality, information retrieval accuracy, and security, reinforcing the credibility of its answers.
