Serverless GPU
Fal.ai
Model APIs: per-model output unit/request; Serverless custom endpoints: per-second runner/GPU time, including billable idle/keep_alive; Compute: per-instance GPU-hour while running.
Managed inference API
Replicate
Official models: model-specific input/output units; community/public models: active hardware time; private models: setup, idle and active hardware time, with labeled fast-boot exceptions.

| Billing | ||
| Billing | Model APIs: per-model output unit/request; Serverless custom endpoints: per-second runner/GPU time, including billable idle/keep_alive; Compute: per-instance GPU-hour while running. | Official models: model-specific input/output units; community/public models: active hardware time; private models: setup, idle and active hardware time, with labeled fast-boot exceptions. |
| GPU choice | ||
| GPU choice | Model APIs manage hardware; custom Serverless chooses supported GPU machine types. Compute offers 1x or 8x H100 SXM instances with full SSH. | Official/public model hardware is managed or model-declared; custom deployments choose supported hardware and instance bounds. |
| Cold start | ||
| Cold start | Cold-start and queue latency vary by model/runner; fal reports caching reduces cold starts, not eliminates all cold starts. | Official models are documented as always warm; community models/zero-minimum custom deployments may incur model-download and startup delay. Set a minimum instance for an always-on custom deployment and pay for that warm capacity. |
| Model access | ||
| Model access | Generative media Model APIs, custom Python Serverless deployments and self-managed weights/stacks on Compute GPU instances. | 100+ official models with stable APIs and predictable output/input-based pricing, plus community and custom models. Community/custom models use hardware-time pricing and can cold start; deployment settings control hardware/autoscaling. |
| Best for | ||
| Best for | Product teams shipping image, video, or audio features without operating GPU fleets | Product teams shipping model-backed features without owning GPU ops |
| Watch out | ||
| Watch out | Choose the product first: Model API output units, Serverless runner lifetime and Compute instance hours bill differently. Compute requires enabled account access; its numeric rates are supplied in the dashboard or by sales. | Per-prediction economics and cold models can surprise at scale |

How to decide
Prefer Fal.ai when product teams shipping image, video, or audio features without operating gpu fleets. Prefer Replicate when product teams shipping model-backed features without owning gpu ops. If those statements both feel true, rent a GPU for control and keep a managed API for peak traffic — do not force one product to do both jobs.
