How costs are calculated

  • LLM services: Token-based pricing (input/output per million tokens)
  • Pay-per-use APIs: Per-request cost from the pricing registry
  • Infrastructure: Monthly plan cost (from your burn0 init config)
Pricing data is fetched from the burn0 backend and cached locally for 24 hours.
