OpenAI launches GPT-6 with interactive Intelligent UI

On September 22, 2026, OpenAI and Anthropic shipped new frontier models on the same afternoon and both cut prices. According to DEV Community, OpenAI launched GPT-6 Sol at $2/$10 per million tokens, 50% below GPT-5.6 Sol's promo prices, along with GPT-6 Luna at $0.10/$0.50. Anthropic launched Claude Opus 5.5 at $4/$20, a 20% list cut from Opus 5's $5/$25, with cache reads down 60% to $0.20 per million. The piece argued this was not a normal price war but a structural drop in inference costs passed through to pricing.

On October 5, IT之家 reported that the full system prompt and tool definitions for OpenAI's current code model, GPT-6 Sol Codex, had been exposed. The leaker @elder_plinius extracted 294,000 characters across 1,902 lines of instruction templates and internal collaboration logic and published them on GitHub. The report described the model as part of the GPT-5.6 Sol line.

Starting October 7, OpenAI began rolling out GPT-6 in ChatGPT together with a new interface called Intelligent UI. Unite.AI reported that the feature lets the chatbot answer with fully interactive user interfaces rather than text alone, starting with paid tiers and reaching Free and Go on October 8.

The Decoder reported that the model can begin responding while still thinking, cutting wait times by 44%, with paying customers on GPT-6 Sol and free users on GPT-6 Luna. 蓝点网 said the interface automatically picks a suitable format: explaining a bicycle's structure lets users tap a diagram to see parts, planning a group meal adjusts quantities with the number of diners, and a savings discussion brings up a calculator directly in the conversation. Users can also ask for a bill-splitting tool or a mini game, while questions needing only a short answer stay in text. The feature rolled out to ChatGPT Plus, Pro, Business and Enterprise users immediately, expanding to ChatGPT Go and free users the next day, with enterprise access depending on IT administrator settings. 开源中国 reported the same rollout schedule and noted clickable buttons, forms, charts, embedded maps and calculators appearing in answers. Wired's assessment held that the update adds visual richness but may be more form than substance in pr
