o3-pro Frequently Asked Questions (FAQ)
Key insights into o3-pro API pricing, context capacity, caching savings, and performance benchmarks
Q. What is the API pricing for o3-pro? How much does it cost per 1M tokens?＋
o3-pro (OpenAI) is priced at $20.0000 per 1 million input tokens and $80.0000 per 1 million output tokens. The output rate is approximately 4.0x higher than the input rate. You can simulate your exact monthly API expenses tailored to your request volume and token length using the calculator above.
Q. What are the context window and maximum output limits of o3-pro?＋
o3-pro features a 200K context window and a maximum output limit of 100K tokens per request. It provides ample capacity for multi-turn dialogs and complex document parsing.
Q. What are the best practices for optimizing API costs with o3-pro?＋
Because output tokens ($80.0000/1M) cost significantly more than inputs, always configure a strict max_tokens ceiling and employ structured output schemas. Additionally, pairing o3-pro with lightweight models for routine tasks via multi-LLM routing can substantially lower total infrastructure spend.
Q. What is the benchmark score (78.5) and performance profile of o3-pro?＋
o3-pro achieves an overall benchmark score of 78.5/100 with a "Very Slow" speed rating. It strikes an optimal tradeoff between high analytical capability, speed, and affordability.
Q. Which alternative models are comparable to o3-pro?＋
Key alternatives in similar price-to-performance tiers include GPT-5 pro, o3-deep-research, Claude Opus 4. We recommend comparing them based on your latency targets, context window needs, and prompt caching benefits using the full comparison tool on this site.
