Calculate what an LLM request costs on Aether API. Pick a model, enter input and output tokens, and see the price per request in USD and credits, including the saving against the provider's own list price.

What this tool answers

• The cost of one request in USD and in Aether credits
• The saving against the provider's own list price
• The cheaper price for cached input tokens, where the model supports it
• The daily cost of a fixed number of requests

How it calculates

• Aether bills per 1M tokens, so a request costs (input tokens x input rate + output tokens x output rate) divided by one million.
• The rates are the ones from the model catalogue, so the number here is the number on the model's own page.
• Credits are priced at $2 per 1M credits, and a dollar amount is converted into credits with that rate.

Frequently asked questions

How is the cost of an LLM request calculated?

Multiply the input tokens by the model's input rate and the output tokens by its output rate, then divide both by one million and add them up. Cached input tokens are billed at the model's cached-input rate instead of the full input rate.

What are Aether credits?

Credits are the prepaid balance the API bills against. One million credits cost $2, and credits never expire, so an unused balance stays usable.

How much cheaper is Aether than the provider's own API?

Every model on Aether API is priced below the provider's own list price - the saving is shown per model and is at least 30% on the catalogue.
