What is GPT-4o (omni)?

‍

GPT-4o (omni) represents a significant leap towards more natural interactions between humans and computers. This model can accept and generate inputs and outputs in text, audio, image, and video formats. With response times as fast as 232 milliseconds, GPT-4o matches the quick reflexes of human conversation.

GPT-4o stands out for its enhanced performance in multilingual, audio, and vision tasks. It matches GPT-4 Turbo in text and coding tasks, with significant improvements in non-English languages. Remarkably, it is faster and 50% cheaper in the API. GPT-4o offers superior understanding and generation in vision and audio compared to previous models.

Model capabilities

GPT-4o can handle diverse tasks, from singing and real-time translation to preparing for interviews and understanding sarcasm. Whether playing rock-paper-scissors, narrating visual stories, or even cracking dad jokes, GPT-4o showcases various interactive abilities. Its role as a text and vision model allows for more dynamic interactions.

Previously, voice interactions with models like GPT-3.5 and GPT-4 involved multiple steps, causing delays and limiting the model's ability to effectively process tone or multiple speakers. Now, GPT-4o integrates all these modalities into a single, cohesive model, enhancing its responsiveness and emotional expressiveness.

Early demonstrations show GPT-4o harmonizing songs, translating languages on the fly, and even providing customer service. It opens up new possibilities for artificial intelligence to assist in everyday tasks, make learning more interactive, and enhance communication across different languages and mediums.
