GPT-4o: The Comprehensive Guide and Explanation
GPT-4o is OpenAI’s third major iteration of their popular large multimodal model, GPT-4, which expands on the capabilities of GPT-4 with Vision. The newly released model is able to talk, see, and interact with the user in an integrated and seamless way, more so than previous versions when using the ChatGPT interface.
In the GPT-4o announcement, OpenAI focused the model’s ability for "much more natural human-computer interaction". In this article, we will discuss what GPT-4o is, how it differs from previous models, evaluate its performance, and use cases for GPT-4o.
OpenAI’s GPT-4o, the “o” stands for omni (meaning ‘all’ or ‘universally’), was released during a live-streamed announcement and demo on May 13, 2024. It is a multimodal model with text, visual and audio input and output capabilities, building on the previous iteration of OpenAI’s GPT-4 with Vision model, GPT-4 Turbo. The power and speed of GPT-4o comes from being a single model handling multiple modalities. Previous GPT-4 versions used multiple single purpose models (voice to text, text to voice, text to image) and created a fragmented experience of switching between models for different tasks.
Compared to GPT-4T, OpenAI claims it is twice as fast, 50% cheaper across both input tokens ($5 per million) and output tokens ($15 per million), and has five times the rate limit (up to 10 million tokens per minute). GPT-4o has a 128K context window and has a knowledge cut-off date of October 2023. Some of the new abilities are currently available online through ChatGPT, through the ChatGPT app on desktop and mobile devices, through the OpenAI API (see API release notes), and through Microsoft Azure.
