OpenAI Launches O3-Pro: Its Most Advanced AI Model Yet

Posted about 2 months ago by Anonymous

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.
