With both ChatGPT and OpenAI’s API, the company plans to “release GPT-5 as a system that integrates a lot of our technology, including o3,” Altman says, adding that “we will no longer ship o3 as a standalone model.” OpenAI first teased o3 in December and launched o3-mini in January.

OpenAI CEO Sam Altman shared the roadmap for GPT-5 and GPT-4.5, and revealed that o3 will no longer launch as a standalone model.

ChatGPT users, including at the free tier, will see GPT-4.5 and GPT-5 next. The hot AI company wants to simplify its GPT and ‘o’ product lines.

GPT-5’s debut will be preceded by the release of a less capable large language model, GPT-4.5, in the coming weeks. The latter algorithm is the successor to the company’s general-purpose GPT-4o model. GPT-4o is less adept at tasks such as generating code than OpenAI’s reasoning-optimized LLMs, but it offers significantly lower inference costs.

OpenAI has canceled the release of its latest major artificial intelligence model, o3, in favor of a "simplified" comprehensive GPT-5 model, it said Wednesday.

OpenAI is nearing the release of a new artificial intelligence model called GPT-4.5 after hitting stumbling blocks in developing the AI system last year.
