gpt-4o · OpenAI
GPT-4o (“o” stands for “omni”) is a new-generation multimodal model designed for more natural human–computer interaction. It can accept any combination of text, audio, image, and video as input, and generate multimodal outputs including text, audio, and images. With audio response latency as low as 232 milliseconds on average around 320 milliseconds, it approaches real human conversational speed. The model delivers strong performance in English text and code, significantly improved multilingual understanding, and outstanding capabilities in visual and audio perception, while offering faster API performance and substantially reduced cost for real-time and complex multimodal applications.

GPT 4o has a 128,000 token context window.
On AIHubMix, GPT 4o costs $2.5 per million input tokens and $10 per million output tokens. Cached input reads are billed at $1.25 per million tokens.
GPT 4o accepts text and image input.
GPT 4o supports tool calling, function calling and structured outputs. Per-protocol parameter support is listed in the capability table on this page.
GPT 4o is available through the AIHubMix unified API. The API is OpenAI-compatible: point your OpenAI SDK at https://aihubmix.com/v1, use your AIHubMix API key, and set the model name to gpt-4o — no other code changes needed.
GPT 4o is developed by OpenAI. AIHubMix aggregates it alongside models from other providers behind one API and one bill.
