How to Optimize Prompts to Save Tokens

Reducing token usage in your prompts can significantly lower API costs while maintaining the quality of AI responses. Here are proven strategies to optimize your prompts.

Remove Unnecessary Words

Every word counts when it comes to tokens. Review your prompts and remove:

  • **Filler words**: "very", "really", "quite", "actually"
  • **Redundant phrases**: "in order to" → "to", "due to the fact that" → "because"
  • **Verbose expressions**: "at this point in time" → "now"

Use Abbreviations and Acronyms

When appropriate, use abbreviations:

  • "artificial intelligence" → "AI"
  • "machine learning" → "ML"
  • "application programming interface" → "API"

Be careful to use only well-known abbreviations that the AI model understands.

Structure Your Prompts Efficiently

Well-structured prompts are more efficient:

  • **Use bullet points** instead of long paragraphs
  • **Number your requirements** clearly
  • **Separate instructions** with line breaks
  • **Use concise language** without losing meaning

Leverage System Messages

If your API supports system messages, use them:

  • System messages are often more efficient than user messages
  • They set context without consuming tokens in each request
  • They help maintain consistency across conversations

Remove Redundant Context

Avoid repeating information:

  • Don't restate context that's already established
  • Remove duplicate instructions
  • Consolidate similar requests into one

Use Examples Sparingly

Examples are valuable but token-intensive:

  • Use 1-2 clear examples instead of many
  • Make examples concise and relevant
  • Remove examples once the pattern is understood

Optimize Output Format Requests

Be specific but concise when requesting formats:

  • Instead of: "Please format your response as a JSON object with the following structure..."
  • Use: "Return JSON: {field1, field2, field3}"

Batch Similar Requests

When possible, combine multiple similar requests:

  • Instead of multiple API calls, make one comprehensive request
  • Use structured formats to handle multiple items at once

Monitor and Iterate

Use Token Counter to:

  • Test different prompt variations
  • Compare token counts before and after optimization
  • Track improvements over time

Best Practices Summary

  1. **Be concise**: Remove unnecessary words
  2. **Be specific**: Clear instructions reduce back-and-forth
  3. **Be structured**: Use formatting to improve clarity
  4. **Test variations**: Compare token usage with Token Counter
  5. **Monitor costs**: Track token usage regularly
