Model providers often charge generated output tokens at a higher rate because generation uses more inference compute.

How AI API cost is calculated
Most model APIs charge input and output tokens separately. Relay services may add a multiplier or custom unit price.
Input tokens+Output tokens×Relay multiplier
01input
Input tokens
Prompt, system instructions, conversation history and tool context are usually billed as input tokens.
02output
Output tokens
Model responses are usually billed as output tokens, often at a higher unit price than input tokens.
03percent
Relay multiplier
Relay sites may apply a markup or package conversion, so compare the final cost with official pricing.

How accurate is the token estimate?
The text tokenizer here is a practical estimate. Exact token counts can vary by model and provider tokenizer.
How should I compare relay pricing?
Compare the final cost after exchange rate, relay multiplier and actual supported model names, not just the advertised unit price.
