OpenAI has announced the rollout of its latest language model, o3-pro, to all ChatGPT Pro and Team users. The new model replaces the previous o1-pro and is now available through the model picker in ChatGPT. Enterprise and Edu users will receive access next week.
The company stated, “OpenAI o3-pro is rolling out now to all Pro users in ChatGPT and in the API.”
According to OpenAI, o3-pro builds on the same underlying model as o3 but shows stronger performance across critical domains.
“In expert evaluations, reviewers consistently prefer OpenAI o3-pro over o3, highlighting its improved performance in key domains—including science, education, programming, data analysis, and writing,” the company said.
The model also passed OpenAI’s “4/4 reliability” benchmark. The rigorous ‘4/4 reliability’ evaluation considers a model successful only if it answers a question correctly in all four attempts rather than just one.
Like its predecessor, o1-pro, the new model maintains strong academic capabilities. “Like OpenAI o1-pro, OpenAI o3-pro excels at math, science, and coding as shown in academic evaluations.”
OpenAI further highlighted the model’s tool integrations. “OpenAI o3-pro has access to tools that make ChatGPT useful—it can search the web, analyse files, reason about visual inputs, use Python, personalise responses using memory, and more.”
Meanwhile, OpenAI has decreased the price of the o3 model by 80%, with input now priced at $2 per million tokens and output at $8 per million tokens. On the other hand, the o3-pro model is priced at $20 per million tokens for input and $80 per million tokens for output—87% cheaper than o1-pro.
OpenAI CEO Sam Altman announced that the company is pushing back the release of its open-weights model, which was initially expected in June. The model will now be released later this summer.
In a post on X, Altman indicated that the team would be taking additional time with their open-weights model, suggesting that it would be expected later in the summer, but not in June.
He added that the delay is due to a new development from the research team, which he described as “unexpected and quite amazing.” According to Altman, “We think it will be very, very worth the wait, but needs a bit longer.”
