これは何か

GPT-4o is a general-purpose model OpenAI released in May 2024; the “o” stands for omni, meaning text, image and audio are handled inside one model. Vision and speech understanding share a single forward pass, and spoken conversation runs at near-real-time latency. Where earlier systems stitched several models into a pipeline, GPT-4o trains multimodality end to end and simplifies the interaction entry point. It is offered through both the API and ChatGPT, and serves as OpenAI’s main multimodal general model.

なぜ覚えておく価値があるか

It moved multimodality from “several models stitched into a pipeline” to “one model end to end” and cut spoken-dialogue latency to near human-conversation levels; general models have since treated native multimodality as the default target.
