According to the plan, OpenAI will release GPT-4.5, internally codenamed Orion, which will be OpenAI's "last non-chained thinking model."
After GPT-4.5, Altman stated thatAn important goal of OpenAI is to "unify the o-series models with the GPT-series models"., by creating systems that can use all of our tools, systems that know when they need to think for long periods of time and when they don't, and can be applied to a wide range of tasks." He mentioned.The company plans to release the GPT-5 as a system integrating several technologies, including o3 technology. He added: "o3 Will no longer be available as a stand-alone model." The o3 technology was first previewed in December 2024, followed by an o3-mini version in January 2025 by OpenAI.

Plus subscribers will be able to use the "higher level of intelligence" of GPT-5, while Pro subscribers will get a "higher level of intelligence experience". However, Altman did not specify when GPT-4.5 and GPT-5 would be released.Only a rough estimate of "weeks / months" is given.
