GPT-4o

GPT-4o ("o" for "omni") is OpenAI's natively multimodal model released in May 2024, accepting text, audio, image, and video inputs and producing text, audio, and image outputs from a single model. The model became OpenAI's default ChatGPT offering, replacing GPT-4 Turbo for most users. GPT-4o's voice mode introduced near-real-time conversational AI with response latencies as low as 320 milliseconds — close to human conversational reaction times. Pricing was set at approximately $2.50 per million input tokens and $10 per million output tokens, making it significantly cheaper than GPT-4 Turbo while delivering comparable or better quality on most benchmarks. GPT-4o supports a 128K context window and powers ChatGPT, Microsoft Copilot, Azure OpenAI Service, and countless third-party integrations. The model represents OpenAI's strategy of unifying modalities into single end-to-end-trained systems. AI governance, AI compliance, and AI risk management programs track GPT-4o usage in inventories supporting responsible AI deployment across enterprise AI portfolios at scale.
