o3 Deep Research

o3 Deep Research is OpenAI's specialized model for extended reasoning and in-depth analysis tasks, featuring a 200k token context window.

Strengths

The model is designed to handle complex research problems through deep reasoning and thorough multi-step analysis without the batch processing constraints.

Best for

Research, investigative analysis, and complex problem-solving tasks that require extended reasoning across a substantial document or knowledge base.

Limitations

The 200k context window is smaller than the 400k window available in most current-generation OpenAI models, and it is positioned as a specialized research tool rather than a general-purpose alternative.
