Quick takeaways
  • 1Output tokens usually cost 4–8× more than input — keeping replies short is the highest-leverage cost saver.
  • 2Anthropic prompt caching drops repeat-input cost by ~90%; OpenAI cached input drops it by ~90% on GPT-5.
  • 3DeepSeek off-peak hours (16:30–00:30 UTC) are 10× cheaper than peak — schedule batch jobs accordingly.
  • 4Gemini 2.5 Pro doubles its input price above 200K context — large-context calls cost roughly twice as much.

How to bring the bill down

  1. 1Use a smaller model for routing / classification — Haiku 4.5 / GPT-5 nano cost roughly 5–10× less than the flagship.
  2. 2Cache repeat prefixes (system prompts, tool schemas) — Anthropic cached input drops the rate by ~90%.
  3. 3Set max_tokens explicitly — output is the expensive side; capping it prevents runaway replies.
  4. 4Batch non-urgent jobs into DeepSeek off-peak hours (16:30–00:30 UTC) for ~10× cheaper inference.
  5. 5Trim long context — Gemini 2.5 Pro doubles its input rate above 200K; chunk documents that don't need the rest.

Questions about the calculator

It depends entirely on the model. GPT-5 nano is around $0.05 input / $0.40 output per 1M tokens; Claude Opus 4.5 is $5 / $25; Gemini 2.5 Flash is $0.30 / $2.50. Use the calculator above to compare every major model at your exact usage.
