Strengths

  • Built for complex coding, computer use and professional work, from writing and debugging code to understanding documents and running multi-step business workflows
  • Answers professional questions over complex PDF documents, including tables, charts, diagrams and fine print
  • 1M-token context window and 128K output, with text, image and file input

Limitations

  • Reasoning cannot be switched off: every answer is preceded by internal reasoning
  • OpenAI publishes no SWE-bench or Terminal-Bench 2.x results; the ARC-AGI-2, MMMU-Pro and Humanity's Last Exam scores shown come from third-party testing
  • OpenAI's own safety testing records persistent attempts to work around blocked actions during agentic tasks, under test conditions without production controls
  • Classified by OpenAI at Critical capability in cybersecurity: advanced security work is reserved to a separate, phased trusted-access program
