o3 Series Models: Enhanced Reasoning and Problem Solving on Azure

Key Capabilities of the o3 Series

• [New!] o3-pro is the latest additon to the o3 model family that is targeted for advanced problem solving by thinking harder and providing consistently better answers.
• The o3-pro model is available only in the Responses API to enable support for multi-turn model interactions.
• 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.
• Instruction Following and Workflow Management: Particularly effective for managing workflows requiring shorter contexts.

Features and properties supported in o3-pro GA model

• Text and image inputs and text output.
• Structured outputs and function calling.

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.
