FAQ

How is the monthly cost calculated?

Monthly cost = (daily input tokens × days × input price per 1M) + (daily output tokens × days × output price per 1M), using provider list prices from the public feed. No markup is added.

Do the numbers include the free tier?

No. The calculator estimates paid usage. The free tier gives 10 free-model calls per day on five models, which is separate from these figures.

Why do costs differ so much between models?

Per-token prices span about 36x between the cheapest and the most expensive text model in this catalog. Input and output are priced separately, and output usually costs 2-5x more per token than input.
