How AI API Pricing Works

AI APIs charge per token processed. Most providers have separate rates for input tokens (your prompt) and output tokens (the model's response). Output tokens typically cost 2-5x more than input tokens because they require more computation.

Tips to Reduce Costs

  • Use smaller models (GPT-4o-mini, Haiku) for simple tasks
  • Keep prompts concise — fewer input tokens = lower cost
  • Set max_tokens to limit output length
  • Use prompt caching where available (Claude, GPT)
  • Batch requests when possible for volume discounts
