OpenAI unveils cheaper small AI model GPT-4o mini

ChatGPT maker OpenAI said on Thursday it was launching GPT-4o mini, a cost-efficient small AI model, aimed at making its technology more affordable and less energy-intensive, allowing the startup to target a broader pool of customers.

Microsoft-backed OpenAI, the market leader in the AI software space, has been working to make it cheaper and faster for developers to build applications based on its model, at a time when deep-pocketed rivals such as Meta and Google rush to grab a bigger share in the market.
