OpenAI o3 and o4-mini

OpenAI o3 and o4-mini represent the most advanced reasoning models ever released, trained to think longer before responding to deliver more accurate and comprehensive answers. These models combine state-of-the-art intelligence with full agentic tool access, enabling them to autonomously search the web, analyze files with Python, reason about visual inputs, and generate images—all while producing detailed responses typically in under a minute.

Product Highlights

• Advanced Reasoning: Pushes the frontier across coding, math, science, and visual perception with significantly fewer errors than previous models
• Multimodal Thinking: First reasoning models to integrate images directly into their chain of thought, enabling visual reasoning and manipulation
• Agentic Tool Use: Autonomously chooses when and how to use tools including web search, Python interpreter, and image generation for complex problem-solving
• Cost Efficiency: o4-mini delivers remarkable performance for its size with higher usage limits, while o3 provides maximum capability for demanding tasks
• Enhanced Safety: Rebuilt safety training with new refusal prompts and system-level mitigations for frontier risk areas

Use Cases

• Complex Research Analysis: Solve multi-step mathematical problems, analyze scientific literature, and generate novel hypotheses across biology, engineering, and physics
• Visual Data Interpretation: Upload whiteboards, diagrams, or sketches for analysis—even blurry or low-quality images—plus dynamic image manipulation during reasoning
• Autonomous Workflow Execution: Chain multiple tool calls to research topics, build forecasts, generate visualizations, and produce comprehensive reports without manual intervention
• Software Development: Code generation, debugging, and architectural planning with state-of-the-art performance on coding benchmarks

Target Audience

Researchers, data scientists, software engineers, business analysts, and advanced ChatGPT users who need sophisticated reasoning capabilities for complex problem-solving, visual analysis, and autonomous task execution across academic and professional domains.
