California: OpenAI has canceled its anticipated o3 model, opting instead to integrate its advancements into GPT-5, CEO Sam Altman announced Wednesday. The shift aims to simplify OpenAI’s offerings and eliminate the need for users to choose between models.
GPT-5, set to roll out in the coming months, will power ChatGPT and OpenAI’s API, incorporating voice, canvas, search, and deep research. Users will get free, unlimited access at a “standard intelligence setting,” while paid tiers will unlock higher intelligence levels.
Before GPT-5, OpenAI will release GPT-4.5, code-named “Orion,” in the next few weeks. It will be the last of OpenAI’s non-chain-of-thought models, unlike o3 and OpenAI’s non-chain-of-thought models are less reliable in math and physics. Moving forward, OpenAI will fully embrace reasoning models—AI that fact-checks itself for greater accuracy, even if it takes longer to respond.
The move comes amid rising competition from China’s DeepSeek, whose open-source R1 model rivals OpenAI’s o1 in benchmarks. Altman acknowledged DeepSeek has narrowed OpenAI’s lead and hinted at accelerated releases to stay ahead.
However, despite reports of performance challenges with Orion, OpenAI is doubling down on reasoning models, betting on GPT-5 to deliver smarter, more seamless AI.
