o3 Deep Research is worth evaluating for rag, agents, and long context when its provider route and context window match the workload.

Use it for

  • Teams evaluating rag, agents, and long context
  • Workloads that can use a 200k context window
  • Buyers comparing 1 tracked provider route

Do not use it for

  • Workloads where another current model has stronger sourced task evidence

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.
