OpenAI is rolling out a more affordable, slimmed-down version of its flagship artificial intelligence model to appeal to a wider range of developers and business customers in an increasingly crowded market for AI services.

The ChatGPT maker on Thursday announced GPT-4o mini, a smaller, cheaper variation of its most capable AI model, GPT-4o. The San Francisco-based startup said the updated model will be available today for free users and paying ChatGPT Plus and Team subscribers, and will be offered to enterprise customers next week. GPT-4o mini is replacing GPT-3.5 Turbo, an older model, in ChatGPT.
