o3 Frequently Asked Questions (FAQ)
Key insights into o3 API pricing, context capacity, caching savings, and performance benchmarks
Q. What is the API pricing for o3? How much does it cost per 1M tokens?＋
o3 (OpenAI) is priced at $2.0000 per 1 million input tokens and $8.0000 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?＋
o3 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. Does o3 support Prompt Caching, and how much cost can be saved?＋
Yes, o3 supports prompt caching. Cached reads cost $0.5000 per 1M tokens, delivering an estimated 75% discount compared to standard input rates. (Minimum cache threshold: 1K) Caching reusable system instructions and documentation substantially lowers recurring API expenses.
Q. What is the benchmark score (76.5) and performance profile of o3?＋
o3 achieves an overall benchmark score of 76.5/100 with a "Slow" speed rating. It strikes an optimal tradeoff between high analytical capability, speed, and affordability.
