GPT-4o Released
- OpenAI announced GPT-4o ("omni") on May 13, 2024, a flagship model that can reason across audio, vision and text in real time[1][3]
- Rollout: text and image in ChatGPT that day, including the free tier, with Plus getting up to 5x higher message limits; new Voice Mode in alpha for Plus in the coming weeks; audio in the API first to a small group of trusted partners[1][3]
- TechCrunch adds a refreshed web UI, a macOS desktop app (Windows later in the year) and free-tier access to the GPT Store, memory and web search[3]
- Safety: evaluated under the Preparedness Framework with no category above Medium risk, and 70+ external red-team experts[1]
- An Apple Podcasts news episode of May 13, 2024 covers the announcement in a segment, but lists only titles[2]
Notable features
- OpenAI trained a single new model end-to-end across text, vision and audio, so all inputs and outputs are processed by the same neural network; the earlier Voice Mode chained three separate models and could not directly observe tone, multiple speakers or background noise[4]
- It takes any mix of text, audio, image and video and generates text, audio and image; audio responses take as little as 232 ms (320 ms on average), versus 2.8 s and 5.4 s for the previous Voice Mode pipelines[1]
- It matches GPT-4 Turbo on English text and code and is better on non-English text, vision and audio, and in the API is twice as fast and half the price with 5x higher rate limits[1][3]
- OpenAI reports state-of-the-art results on visual perception benchmarks, with new high watermarks on multilingual, audio and vision capabilities[4]
- A new tokenizer uses fewer tokens across 20 languages (for example Gujarati 4.4x fewer)[1]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
