OpenAI will not release "o3" as a standalone artificial intelligence model, as the ChatGPT maker looks to simplify its products, CEO Sam Altman said on Wednesday.

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.

US companies face greater investor scrutiny over their massive spending after Chinese start-up DeepSeek unveiled a low-cost AI model OpenAI would not release "o3" as a stand-alone artificial intelligence (AI) model,

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, the artificial intelligence research lab, has unveiled its roadmap for the upcoming releases of GPT-4.5 and GPT-5. The lab aims to simplify its product offerings and plans to integrate all its technologies into one unified system.
