Overview

OpenAI: o1 is a large language model API from OpenAI, part of its o1 model family. At $15.00 per million input tokens and $60.00 per million output tokens, it is priced as a flagship model, typically reserved for tasks where quality outweighs cost. Output tokens cost about 4× as much as input, so prompt-heavy workloads run noticeably cheaper than generation-heavy ones. A large 200K-token context window (≈300 pages of text) lets it take in whole books, large codebases, or lengthy transcripts in a single call. Beyond plain text it also accepts Image, File input, so it can be applied to multimodal tasks rather than text alone. On Artificial Analysis's Intelligence Index it scores 23 (D grade), a useful proxy for its general reasoning strength relative to the other models tracked here. All prices on this page reflect OpenRouter's routed rates and are re-synced automatically every day; confirm against the provider's official pricing before committing to production.

Use Case Analysis

Model strengths, weaknesses, and ideal use cases based on benchmarks and official documentation

Strength

  • Complex Reasoning Trained with reinforcement learning to perform complex reasoning. Produces long chain-of-thought before responding. Official
  • STEM Excellence Exceptional performance on math, physics, chemistry, and coding problems. Official

Best For

  • Complex Problem Solving Math proofs, physics problems, complex algorithms, research. Official

Weakness

  • Slower Response Time Takes longer to respond due to internal reasoning process. Official
  • Text-Only Input Text input only. No image, audio, or video support. Official

Not Recommended

  • Real-time Applications Slow response time makes it unsuitable for real-time interactions. Official
