Billing

FIM Gate prices in US dollars and charges based on actual usage. Live prices for all models are listed on the pricing page — this page only explains how costs are calculated and does not maintain any price snapshots.

Token-based billing

Most text models are billed by token usage: input and output are priced separately, and rates vary by model.

Cost = input tokens × input rate + output tokens × output rate

The pricing page lists each model's input and output rates and pricing units. Tokens generated by features such as caching and thinking also count toward usage; the usage field in each response reports the actual consumption of that request.

Example: suppose a model is priced at $0.40 per million input tokens and $1.60 per million output tokens, and a request consumes 2,000 input tokens and 1,000 output tokens:

Cost = 2000 / 1,000,000 × 0.40 + 1000 / 1,000,000 × 1.60
     = 0.0008 + 0.0016
     = $0.0024

Per-call billing

Some multimedia APIs are billed per call: each successful call incurs one charge, regardless of the length of the generated content. The applicable APIs and per-call prices are also listed on the pricing page.
