About this model

The o1 series models are specifically designed to tackle reasoning and problem-solving tasks with increased focus and capability. These models spend more time processing and understanding the user's request, making them exceptionally strong in areas like science, coding, math and similar fields.

Key model capabilities

  • o1 adds advanced image analysis capabilities with the new version. Enhance your prompts and context with images for additional insights.
  • Complex Code Generation: Capable of generating algorithms and handling advanced coding tasks to support developers.
  • Advanced Problem Solving: Ideal for comprehensive brainstorming sessions and addressing multifaceted challenges.
  • Complex Document Comparison: Perfect for analyzing contracts, case files, or legal documents to identify subtle differences.
  • Instruction Following and Workflow Management: Particularly effective for managing workflows requiring shorter contexts.
Features and properties supported in o1 GA model include:
  • Developer message replaces system message
  • Reasoning effort as in high, medium, and low. It controls whether the model thinks "less" or "more" in terms of applying cognitive reasoning.
  • Vision input, structured outputs, and tools.
Model Variants:
  • o4-mini: The most efficient reasoning model in the o model series, well suited for agentic solutions. Now generally available.
  • o3: The most capable reasoning model in the o model series, and the first one to offer full tools support for agentic solutions. Now generally available.
  • o3-mini: A faster and more cost-efficient option in the o3 series, ideal for coding tasks requiring speed and lower resource consumption.
  • o1: The most capable model in the o1 series, offering enhanced reasoning abilities. Now generally available.
  • o1-mini: A faster and more cost-efficient option in the o1 series, ideal for coding tasks requiring speed and lower resource consumption.
