What OpenAI announced
On 7 Oct 2026, OpenAI released GPT-6 in ChatGPT — Sol for paid, Luna for free, Astra for hard reasoning for chat / reasoning work. Three tiers by speed and cost, plus Intelligent UI in ChatGPT (text mixed with diagrams, charts, forms and tappable buttons where it fits).
OpenAI’s own announcement, on 7 October 2026, puts the ChatGPT rollout in clear tiers: paid Plus, Pro, Business and Enterprise users get GPT-6 Sol, while Free and Go users get GPT-6 Luna. The headline feature in that announcement is Intelligent UI, where ChatGPT can answer with text plus visuals, charts, forms and tappable buttons where that format fits the question — and plain text where it does not. Check your own ChatGPT account, not a headline, before assuming which tier you are on, because later Help-page updates cast free-tier access into doubt.
What it costs, and who can use it today
Price: Sol $2 / $10 per 1M tokens; Luna $0.10 / $0.50 per 1M tokens; Astra price not published in sources checked. Access: General. Availability: Paid Plus/Pro/Business/Enterprise: Sol from 7 Oct in ChatGPT; Free/Go: Luna following; rollout began 7 Oct 2026 — free-tier access was contested in later Help-page updates, so check your account. A token, where prices are per million tokens, is roughly part of a word; prices are per million tokens processed, not per message. Open-weight means downloadable weights — check the licence for commercial use, because downloadable does not automatically mean unrestricted.
Why it matters
Most readers will meet GPT-6 as “ChatGPT changed”, not as an API price. Both views belong on the same page.

Also checked: AI Startups News summary of the GPT-6 rollout, plus VentureBeat pricing — a calendar or category page verifies date, lab and type only, not price or access.
Official sources are listed first, because a lab’s own announcement or product page is the primary source for price, access and availability. Secondary coverage is listed second, and is never used to upgrade an unverified figure into a settled fact.
