OpenAI plans to release new GPT-4.5 model in coming weeks, says Altman

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.

In a series of posts on social network X on Wednesday, OpenAI Chief Executive Officer Sam Altman said the model, which the company has referred to as Orion internally, would come in a matter of “weeks.” Bloomberg News reported in November that Orion had not been hitting OpenAI’s desired performance.
