The move signals OpenAI's growing ambitions beyond improving accuracy and predictability. Last month, for example, OpenAI said its new ChatGPT-4.5 has improved emotional intelligence compared to previous models, with the ability to recognize patterns, draw connections and think more creatively, according to the company.

In a post on X on Tuesday, OpenAI CEO Sam Altman said that the company has trained a “new model” that’s “really good” at creative writing. He posted a lengthy sample from the model given the prompt “Please write a metafictional literary short story about AI and grief.”
