o1-pro

o1-pro by OpenAI excels in the Coding category, where it ranks #71 with a composite score of 73/100. The o1 series of models are trained with reinforcement learning to think before they answer and perform complex reasoning. The o1-pro model uses more compute to think harder and provide... It is particularly strong in areas highlighted by its top benchmark performance and adoption metrics, making it suitable for both individual developers and enterprise teams looking for a reliable coding solution.

o1-pro is priced at $150.00 per million input tokens and $600.00 per million output tokens (USD). Contact the provider for volume discounts and enterprise pricing. Pricing is competitive within the coding category and reflects the model's quality-to-cost ratio.

In the Coding category, o1-pro holds rank #71 out of 317 models tracked. Its quality rank is #71 and adoption rank is #71. You can use our comparison tool at /compare to see detailed side-by-side metrics with specific alternatives. Key differentiators include its composite scoring across benchmarks, community sentiment, and real-world adoption rates.

o1-pro has been evaluated across 6 different signals. Its strongest areas include Capabilities (67/100), Benchmarks (77/100), Pricing (5/100). These scores are derived from industry-standard benchmarks, community ratings, and real-world performance metrics. The composite score of 73/100 reflects a weighted combination of all tracked signals.

o1-pro is a paid model, though some providers may offer trial credits or limited free tiers for evaluation. Check OpenAI's website for current free tier availability and promotional offers.

o1-pro supports a 200K token context window (200,000 tokens total). That translates to roughly 150,000 words in a single prompt. This is large enough to process entire codebases, research papers, or long conversation histories in one shot.

o1-pro can generate up to 100K output tokens (100,000 tokens) per response. That is roughly 75,000 words. This is enough for generating complete code files, detailed reports, or long-form content in a single response.

o1-pro supports image understanding (vision), structured JSON output, extended reasoning/chain-of-thought, streaming responses. Vision support means it can analyze images, screenshots, and diagrams alongside text. These capabilities determine which workflows and integrations the model can handle natively.

o1-pro was developed by OpenAI. It was released on March 19, 2025. You can access it through OpenAI's API. Check our provider page for all models from OpenAI and how they compare against each other.

Pick o1-pro when you need a solid balance of cost and capability for everyday development tasks, content generation, and standard API integrations. If your task is straightforward text completion or classification, a cheaper model might give you 90% of the quality at a fraction of the price. Run a quick benchmark on your actual use case before committing.

You can access o1-pro through OpenAI's API using standard HTTP requests or their official SDK. Most providers support OpenAI-compatible endpoints, so switching between models often requires changing just the model name in your API call. Streaming is supported for real-time token-by-token output. For production use, implement proper error handling, rate limiting, and cost monitoring.
