OpenAI announced a new AI model yesterday called GPT-4o that can converse using speech in real time, read emotional cues, and respond to visual input. It will roll out over the next few weeks for free to ChatGPT users and as a service through API. Paid subscribers will have five times the rate limits of free users. The API will feature twice the speed, 50% lower cost, and five times higher rate limits compared to GPT-4 Turbo. A 26-minute long video that introduces GPT-4o and demonstrates its abilities is available in the article.
