How to use this hub

Start with token or API cost if you know request volume and average prompt/output sizes.
Use agent cost when one user action can trigger multiple model calls, tool calls, or retries.
Use inference, training, subscription, and ROI calculators when comparing operating models or vendors.

Common use cases

Estimate token-based API costs for LLM products.
Budget AI agents, retries, tools, and successful runs.
Compare subscription, inference, training, and AI content ROI scenarios.

Questions this hub answers

Why are AI cost estimates hard?

Costs depend on model prices, input and output tokens, retries, context size, tool calls, latency targets, and how often users complete a workflow.

Should I estimate by request or by token?

Token estimates are better for LLM APIs. Request estimates are useful for rate limits, latency budgets, and non-token infrastructure planning.
