OpenAI’s newest model is GPT-4o

OpenAI is releasing a new flagship generative AI model called GPT-4o, set to roll out “iteratively” across the company’s developer and consumer-facing products over the next few weeks. (The “o” in GPT-4 stands for “omni.”)

OpenAI CTO Muri Murati said that GPT-4o provides “GPT-4-level” intelligence but improves on GPT-4’s capabilities across text and vision as well as audio.

“GPT-4o reasons across voice, text and vision,” Murati said during a keynote presentation at OpenAI’s offices. “And this is incredibly important, because we’re looking at the future of interaction between ourselves and machines.”

GPT-4 Turbo — OpenAI’s previous leading model, an enhanced version of GPT-4 — was trained a combination of both images and text, and could analyze images and text to accomplish tasks like extracting text from images or even describing the content of those images. But GPT-4o adds speech to the mix.

What does this enable, concretely? A variety of things. 

 

GPT-4o greatly improves the ChatGPT experience — ChatGPT being OpenAI’s viral AI-powered chatbot. ChatGPT has long offered a voice mode that transcribes text from ChatGPT using a text-to-speech model. But GPT-4o supercharges this, allowing users to interact with ChatGPT more like an assistant. 

For example, users can ask ChatGPT — powered by GPT-4o — a question and interrupt ChatGPT while it’s answering. The model delivers “real time” responsiveness, OpenAI says, and can even pick up on the emotion in a user’s voice, and generate voice in “a range of different emotive styles.”

GPT-4o improves ChatGPT’s vision capabilities as well. Given a photo — or a desktop screen — ChatGPT can now quickly answer related questions, from things like “What’s going on in this software code” to “What brand of shirt is this person wearing?”

GPT-4o is available in the free tier of ChatGPT starting today, and to subscribers to OpenAI’s premium ChatGPT Plus with “5x higher” message limits. OpenAI says that it’ll roll out the improved voice experience underpinned by GPT-4o in alpha to Plus users in the next month or so.

“We know that these models [are getting] more and more complex, but we want the experience of interaction to actually become more natural, easy, and for you not to focus on the UI at all, but just focus on the collaboration with [GPTs],” Murati said.

GPT-4o is more multilingual as well, OpenAI claims, with improved performance in 50 different languages. In OpenAI’s API, GPT-4o is twice as fast as GPT-4 (specifically GPT-4 Turbo), half the price and has higher rate limits. 

Voice isn’t a part of the GPT-4o API for all customers at present. OpenAI, citing the risk of misuse, says that it plans to first launch support for GPT-4o’s new audio capabilities to “a small group of trusted partners” in the coming weeks.
