Fal.ai's Pricing

Usage-based

Hosted APIs use endpoint-specific output billing. Custom GPU deployments have separate machine rates. Check the selected endpoint and account before generation.

Hosted model APIs

Per output unit

image, megapixel, video or second - None stated

Custom GPU compute

H100 $4.50/hour list; as low as $1.89/hour

GPU hour - None stated

Watch-outs

Free tools or Sandbox access do not establish a free allowance for every hosted endpoint.
Hosted model prices and GPU deployment prices are different products.

Frequently Asked Questions

What is fal.ai?

fal.ai is a developer platform for generative media inference, with APIs for image, video, audio and other models plus serverless and dedicated compute options.

How does fal.ai pricing work?

Hosted models are billed by output unit, such as image, megapixel, video or second; custom deployments use GPU-time pricing. Model and machine rates are route-specific.

Does fal.ai have a free tier?

fal offers separate free tools and Sandbox exploration. Check the account and endpoint for any available allowance; paid model API use is billed by the applicable output or compute unit.

What does FLUX1.1 [pro] cost on fal.ai?

The endpoint says $0.04 per megapixel and bills by rounding up to the nearest megapixel. This is distinct from BFL's $0.04 per image price.

Can fal.ai host custom models?

Yes. fal offers serverless model deployment and GPU compute. Check the selected deployment arrangement and pricing.
