OpenAI Launches O3-Pro: Its Most Advanced AI Model Yet
OpenAI’s New Flagship AI Model Outperforms Predecessors
OpenAI has officially unveiled o3-pro, marking a significant leap forward in artificial intelligence capabilities. This latest reasoning model builds upon the o3 architecture introduced earlier this year.
What Makes O3-Pro Special?
Unlike conventional AI models, o3-pro excels at complex problem-solving through step-by-step reasoning. This architectural advantage makes it particularly effective for technical domains including:
- Advanced mathematics and physics
- Computer programming
- Scientific research applications
- Business analytics
Availability and Pricing
The new model is currently rolling out to different user tiers:
- ChatGPT Pro and Team users: Available now (replaces o1-pro)
- Enterprise and Education users: Coming next week
API Access and Token Pricing
Developers can now access o3-pro through OpenAI’s API with the following pricing structure:
- Input tokens: $20 per million (approximately 750,000 words)
- Output tokens: $80 per million
Performance Benchmarks
OpenAI’s internal testing demonstrates o3-pro’s superiority across multiple metrics:
- 41% higher reviewer preference compared to o3
- Outperforms Google’s Gemini 2.5 Pro on AIME 2024 math evaluations
- Beats Claude 4 Opus on PhD-level science assessments (GPQA Diamond)
Enhanced Capabilities
The model introduces several advanced features including:
- Web search functionality
- File analysis tools
- Visual input processing
- Python code execution
- Personalized response generation
Current Limitations
While powerful, o3-pro comes with some temporary restrictions:
- Temporary chat sessions currently disabled
- No image generation capabilities
- Incompatible with Canvas workspace feature
- Slightly slower response times than o1-pro
OpenAI continues to refine o3-pro, promising updates to address these limitations in future releases.
