OpenAI is launching GPT-4o, an iteration of the GPT-4 model that powers its hallmark product, ChatGPT. The updated model “is much faster” and improves “capabilities across text, vision, and audio,” OpenAI CTO Mira Murati said in a livestream announcement on Monday. It’ll be free for all users, and paid users will continue to “have up to five times the capacity limits” of free users, Murati added.
