by OpenAI·Released 22 September 2026
GPT-6 Luna Pro is GPT-6 Luna in a Pro mode that thinks much longer before it answers. It reads text, pictures and files and writes back, and each request uses far more thinking, so replies arrive much later. It fits a hard, high-stakes problem where extra accuracy is worth the wait; routine chat, sorting and light multi-step work should stay on plain GPT-6 Luna, and GPT-6 Sol Pro is the step up for heavier coding.

Deposit dinars with your Edahabia or CIB card. Every model, GPT-6 Luna Pro (batch) included, is paid from that balance. No foreign card, no conversion.
OpenAI names no languages for GPT-6 Luna Pro (batch). Arabic, French and Darja: not stated.
It reads text, images and PDFs. Up to 1.1M tokens in one request, about 1 000 pages. It writes up to 96 000 words at once.

OpenAI. Released 22 September 2026. It knows the world up to May 2026.
Text Embedding 3 Small turns text of up to about 8 pages into a fingerprint of its meaning, so search finds passages that mean the same thing even when the words differ. It replaces the older ada-002 and is the sensible default for search over your documents, grouping similar messages or labelling them.
GPT Image 2.5 Sunburst takes a written description, with optional reference pictures, and gives back an image, new or edited, as PNG, JPEG or WebP, with transparent backgrounds on PNG and WebP. It is the precision tier of the 2.5 series, for detailed creative work where an edit has to land exactly as asked, and it adds top quality settings named xhigh and max.
GPT-6 Luna Decisions does not write text. You send content as text, a table of data or a picture, plus up to 200 named questions of three kinds: yes or no, pick among options, or grade against an ordered scale. It returns a probability for every answer, with the likeliest option or expected score, so your own system can set its thresholds for routing, moderation or marking.
Text Embedding 3 Large turns text of up to about 8 pages into a fingerprint of its meaning, so search finds passages that mean the same thing even when the words differ. It is the most accurate of OpenAI's models of this kind, in English and other languages. Choose it when the quality of matches matters most, for search, grouping or labelling documents.
