About
o3-deep-research is OpenAI's advanced model for deep research, designed to tackle complex multi-step research tasks by synthesizing information from multiple sources at 200K context.
o3 Deep Research is a proprietary model in the o3 family. The structured metadata tracks a 200k-token context window, multimodal input, reasoning, function calling, tool use, and structured outputs. This page tracks provider routes through Vercel AI Gateway, with the cheapest tracked route listed at $10 input and $40 output per 1M tokens. No headline benchmark score is tracked for o3 Deep Research yet.
