AI model prices can change and may differ by provider, model version, usage tier, cached input, region, or other billing rules. Treat this calculator as an estimate.

What does an LLM Cost Calculator do?

An LLM Cost Calculator estimates the cost of using a large language model based on the number of input and output tokens. This can help developers estimate the approximate cost of AI API requests before deploying an application.

The calculator separates input and output costs because many AI providers use different prices for tokens sent to and generated by the model.

How to use the LLM Cost Calculator

1. Select a model: Choose the model category that best represents your use case.
2. Enter input tokens: Add the estimated number of tokens sent to the model.
3. Enter output tokens: Add the estimated number of tokens generated by the model.
4. Review the result: Check the input cost, output cost, and estimated total.
