o3-deep-research
o3-deep-research is a distinct o3 specialization for multi-step information gathering and synthesis. It can search the web and use externally supplied data through MCP connectors, producing research reports with tool-derived evidence. The API release provided a programmatic counterpart to deep research workflows. Its specialized tool interface differs from general-purpose function-calling models.
