OpenAI brings GPT-6 to ChatGPT's free users

OpenAI is releasing a new GPT-6 model built for the more than 1.2 billion people who use ChatGPT each week. The first GPT-6 models went to paid customers last month.

The main new feature is Intelligent UI. GPT-6 is trained to build its responses from text, visuals and interactive elements such as charts, forms, tappable buttons and maps, and to decide which format suits each question. Users can also ask it to build a small tool on the spot, such as a savings calculator, a bill splitter or a game. OpenAI says it built a library of native, streamable components and a compiler that renders the interface as the model generates it, so the UI can appear piece by piece instead of all at once. The company acknowledges there is "still work ahead" on the model's design judgment.

GPT-6 can also start answering while it is still reasoning. It builds the answer over several partial responses rather than waiting for its reasoning to finish. OpenAI cites internal evaluations only:

• On everyday agentic tasks, GPT-6 Extra High begins answering as quickly as GPT-5.6 Medium and scores higher overall than GPT-5.6 Extra High.
• On questions that need web search, GPT-6 Instant starts answering 44% sooner on average than GPT-5.6 Instant.

On safety, OpenAI reports stronger resistance to jailbreaks, particularly attacks that adapt across multiple turns, and updated protections for cyber, biological and violence-related misuse. Details are in a system card.

The availability section of the source text was cut off, so the rollout schedule and how access differs by tier are not yet clear.
