One9Founders Verdictgood

OpenAI's dedicated reasoning model. o3 sits in the top 30 on Arena with strong math performance (#14 math). At $2/M it's more affordable than expected for a reasoning model. No vision or multimodal support — pure reasoning focus.

When you need to think hard, not fast. Solid reasoning at a fair price.

Best For

  • mathematical problem solving
  • complex multi-step reasoning
  • scientific analysis
  • code logic verification

Not Great For

  • multimodal tasks
  • creative writing
  • cost-sensitive high-volume tasks

Startup Recommendation

Teams building reasoning-heavy applications like code analysis, math tutoring, or scientific tools.
