GPT-4o
Omni, the current flagship standard model from OpenAI, integrates “seeing, hearing, and speaking.” Unlike previous models that processed “text,” “audio,” and “images” with separate AI systems and then stitched them together, GPT-4o natively handles all three within a single model. This enables science fiction-like multimodal experiences, such as voice conversations with ultra-low latency, akin to human interjections, and real-time recognition and commentary on camera footage. It is the version that serves as the face of ChatGPT today, offered widely from free users to Pro users.
