fal.ai vs Synexa

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Synexa publishes a starting price ($0.00); fal.ai does not. Both ship a public API.

fal.aiDeveloper platform serving 1,000+ generative image, video and audio models through one metered APISynexaServerless API for running 100+ open image, video and audio models, billed per second

What our research says

fal.ai

A strong default for shipping generative media features: broad model coverage, fast inference and per-output pricing you can compute margins on. It is infrastructure - expect to build your own product surface, and watch per-second video rates because they compound quickly at scale.

Pros

  • Model catalog spans image, video, audio and 3D from many vendors
  • Per-output pricing published per model, so unit economics are computable
  • Named production users at large scale (Canva, Perplexity cited on site)
  • Private deployments and compute clusters for enterprise workloads

Cons

  • Costs scale directly with usage and need your own capping controls
  • No consumer-grade creation interface
  • Model availability and prices shift as upstream vendors update terms

Synexa

Synexa is a Replicate-shaped service with published per-second GPU rates that undercut the usual A100 pricing, and scale-to-zero means an idle project costs nothing. Per-run prices for the popular image models are listed openly, which makes cost modelling straightforward. The problem is provenance: the terms of service name no company, no jurisdiction and no address, which is a hard sell for anything beyond side projects.

Pros

  • Per-second GPU rates published openly, down to $0.000119 on a 3090
  • Flat per-run prices for the common image, video and 3D models
  • Scale-to-zero, so idle projects cost nothing
  • REST plus Python and JavaScript SDKs, with a single-POST run flow

Cons

  • No legal entity, address or country published anywhere, including the terms
  • The 99.9% uptime and sub-100ms routing claims come with no status page evidence
  • Model catalogue is open weights only
  • An about page exists in the navigation but returns 404

Which one fits

Choose fal.ai if you need

  • Product teams adding image or video generation to their own apps
  • Developers comparing many models without separate vendor accounts
  • Startups renting serverless GPU capacity instead of managing clusters

Choose Synexa if you need

  • Developers running FLUX or SDXL image generation behind their own app
  • Bursty workloads that would waste money on a reserved GPU
  • Teams comparing per-run cost against Replicate or Fal
