#2 for reasoningGPT-6 Astra reads your text and pictures and writes back, taking in about a thousand pages at once and writing up to 128 pages in one answer. It is the flagship of the GPT-6 series, aimed at big end-to-end jobs such as analysis, building software, researching a subject in depth, science and writing documents, with extra strength on long tasks that drive a computer or browser. GPT-6 Sol is the cost-efficient step below, GPT-6 Luna the fast one, and GPT-6 Astra Pro adds a deeper-thinking mode.

GPT-6 Luna reads your text, pictures and files and writes back, and it can take in about a thousand pages at once. It is the quick, low-cost tier of the GPT-6 series, below GPT-6 Sol, built for heavy traffic and tight response times: chat, sorting messages into categories and light multi-step tasks. Turn its thinking up and it can also take software and computer-use jobs that used to need a Sol-class model.
A faster, more efficient GPT-5.4 for production at scale, serving chat apps, coding assistants and agent workflows with reliable instruction following and solid multi-step reasoning over text and images
#3 for reasoning · GPT-6.1 Sol reads your text, pictures and files and writes back, and it can take in about a thousand pages at once. It upgrades GPT-6 Sol and sits below the flagship Astra, aimed at coding on its own over many steps, operating a computer, professional work built on large documents and multi-step business automation. Compared with the model it replaces, it gets facts wrong less often and follows stated limits and the user's intent more closely, while landing near Astra on these jobs for far less.
#5 for reasoning · This model reads text, pictures and files, taking in about a thousand pages at once, and writes back as many as 120 pages. It thinks before answering, can search the web and run the tools you give it, so it suits everyday coding, writing and multi-step work at the computer. It stands out at making sense of screenshots, and it sits in the middle of its family: the bigger relation above it reads the same amount but costs more to run. It gives back only text, so a job that needs a picture or a voice reply calls for a different kind of model.
