GPT-4o is OpenAI's latest multimodal model that handles text, code, images, audio, and video in one network. It matches GPT-4 Turbo on English tasks, is stronger in other languages, and offers a 128k context window with ~300 ms speech response at half the price.
Developers get a single, cheaper endpoint for chat, coding, voice, and vision features without juggling multiple models or pipelines. The large context and real-time audio enable fast assistants and rich multimodal analysis in any app.
