About
OpenAI GPT-4o: Flagship multimodal model with vision, function calling, and broad capability. $2.50/M input, $10/M output.
GPT-4o is a proprietary model. The structured metadata tracks a 128k-token context window, multimodal input, function calling, tool use, structured outputs, and code execution. This page tracks provider routes through Replicate API, OpenRouter, Azure OpenAI, and 2 more, with the cheapest tracked route listed at $2.5 input and $10 output per 1M tokens. Headline tracked benchmarks include Chatbot Arena 1315.0, Google-Proof Q&A 50.6, and Massive Multi-discipline Multimodal Understanding 69.1.
