Pricing

Flow AI charges each model at its list price, with no subscription. Current prices are on the Models page and each model’s own page.

Units

A model’s type decides the unit it’s priced in.

Tiers

Some models have more than one price:

• Chat models can be priced by context length, so long prompts cost more per token. The Models page shows the lowest price as “from $X”; the model’s page lists each tier.
• Cached input: models that support prompt caching list separate prices for cache reads and writes.
• Video models can be priced by resolution.

What a request costs

A request costs its usage times the price: tokens in and out for chat and embeddings, images for image models, seconds for video. The Logs page shows each request’s usage and the exact price applied. Prices are in $THINK, where 1 THINK =$1 of usage.
