Project
tokenometer
Estimate prompt spend before execution and price actual provider usage after each LLM step.
Focus
GitHub Description
Token counting, cost modeling, and runtime LLM usage pricing.
- Makes LLM token and cost tradeoffs visible before integration work starts.
- Useful for prompt iteration, provider comparison, and runtime budget-aware AI tooling.
- The Tokenometer website is the canonical live experience for the project.
Preview / Demo
Basic token-cost estimate
A 1,250 token prompt plus a 350 token response is roughly 1,600 total tokens. Tokenometer now also prices completed provider usage, which is the missing primitive for multi-step agent budgets.
Basic Demo
Tokenometer helps estimate token volume before LLM work becomes spend.
Example estimate: a 1,250 token prompt with a 350 token response is roughly 1,600 total tokens. At $0.00001 per token, that single call is about $0.016 before batching, retries, or multi-step chains. The core library can also price completed provider usage after each step.
