Best Practices for Using o1-pro APIs

To maximize the effectiveness of o1-pro and optimize your costs:

2. Use System Messages Effectively: Set the context with system messages to guide o1-pro toward the reasoning approach you want. Be specific about the type of reasoning (deductive, inductive, etc.) you're expecting.

Adjust Temperature Parameters:

• Lower temperature (0.1-0.3) for more precise, deterministic reasoning and mathematical problems
• Moderate temperature (0.3-0.7) for balanced reasoning with some flexibility
• Higher temperature for more creative problem-solving approaches

1. Request Step-by-Step Thinking: Explicitly ask for detailed reasoning steps when solving complex problems. Phrases like "Think through this step by step" or "Show your reasoning" help activate o1-pro's strengths.
2. Monitor Token Usage: Keep track of input and output tokens to manage costs effectively. Consider implementing a token estimation function in your application.
3. Batch Related Queries: When possible, combine related questions into a single API call rather than making multiple separate calls.
4. Implement Caching: Cache common responses to avoid redundant API calls for frequently requested information.
5. Use Chain-of-Thought Techniques: For complex problems, implement chain-of-thought prompting by asking the model to "think about this problem step by step before providing the final answer."
