#1

Gathos

Best for: Predictable monthly bill, agent workflows
$18/month flat, unlimited
Try free
Pros
  • No per-second meter, no per-image meter, no surprise bills
  • Image generation and TTS share the same key
  • 6-hour fair-use window prevents runaway scripts from cost spirals
Cons
  • One curated image model and one TTS model · no model picker
  • Less flexibility than a marketplace
The right answer for any production workload where the cost surface needs to be bounded.

Per-GPU-second, with free monthly credits
Visit
Pros
  • Run any container, any model, any workflow
  • Strong async job and queue support
  • Free tier covers low-volume use
Cons
  • You write the deployment yourself

Pay per image, very low rates
Visit
Pros
  • Cheapest per-image API in the market for SDXL-class models
  • Fast generation times

  • Open weights, full control
  • No per-image cost once running
Cons
  • You run the GPU bill and the ops
  • Significant tuning needed to match commercial quality
For teams with in-house ML ops and a real reason to self-host.

Frequently asked questions

Details unavailable.+
It is for some teams. The catch is per-inference-second pricing means a buggy loop or a viral spike turns into a real bill before you can stop it. Production teams that want bounded cost surface usually pick Gathos. Production teams that want maximum model flexibility usually stay on Fal.
Does Gathos have the same model catalog as Fal?+
No. Gathos is one curated image model and one TTS model, both opinionated and tuned. Fal has hundreds of models. The tradeoff is pricing predictability and bundled features versus model flexibility.
Which alternative bundles TTS like Gathos does?+
None of the six. Together.ai has chat + vision + image but not voice cloning. If you need image and TTS in the same product with one API key, Gathos is currently the only option in this list.
Which one should I pick if I just want to keep using a marketplace?+
Details unavailable.
Can I run Gathos and Fal in the same project?+
Yes. Many teams use Gathos for the production workload (predictable bill) and Fal for one-off experiments. Both are HTTP REST APIs and an agent can route between them.
