Source: OpenAI

OpenAI announced GPT-4o on 13 May 2024, a model that accepts any mix of text, audio, image and video and produces text, audio and image output. It answers audio in as little as 232 milliseconds, 320 on average, against 5.4 seconds for the earlier GPT-4 voice mode, and in the API it was twice as fast as GPT-4 Turbo at half the price with five times the rate limits. Its text and image features rolled out to the free ChatGPT tier.

Why it matters

Free ChatGPT users got OpenAI’s flagship model, and developers got it at half the API price of GPT-4 Turbo, which cut the cost of building on a top model.
