OpenAI announced on October 7 that GPT-6 is officially entering ChatGPT: paid users get GPT-6 Sol first, free and Go users get GPT-6 Luna in batches from October 8. The simultaneously launched Intelligent UI puts charts, buttons, and interactive widgets directly in answers — output is no longer text-only.
At DevDay 2026, OpenAI launched the $500-a-month Pro 500 subscription with the new Ultrafast speed tier, making Codex token generation up to 8x faster. Meanwhile the $200 Pro tier reopened for subscriptions — with its allowance cut in half.
On September 29 local time, OpenAI's 2026 developer conference brought 20+ updates: the always-on agent Dots works independently and connects 4,000+ apps, new model GPT-6.1 Sol launched, and team workspace ChatGPT Space debuted. Five minutes to the three highlights.
