Overview

About Synexa

Synexa runs hosted AI models behind a single HTTP API: one POST with an API key starts image generation, video generation, restoration, captioning, speech or a fine-tune, with Python and JavaScript SDKs alongside REST. The gallery lists more than a hundred models, mostly open weights such as FLUX, Stable Diffusion XL, Wan and Hunyuan, alongside hosted proprietary ones such as Google's Veo 3.1 and Nano Banana Pro. Infrastructure scales to zero when idle, so you pay only for compute consumed. Pricing is published two ways: per second of GPU time, from $0.000119 on an RTX 3090 to $0.00083 on an H100, and as flat per-output rates such as $0.0015 for a FLUX schnell image. The site names no company entity or country.

Editorial verdict

Pros & cons of Synexa

medium confidence

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, and the terms' governing-law clause still reads '[Jurisdiction]'
  • The 99.9% uptime and sub-100ms routing claims come with no status page evidence
  • Per-output price table omits the currency sign
  • An about page exists in the navigation but returns 404

Best for

  • 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

Not for

  • Production systems that need a contractable vendor and an SLA in writing
  • Teams whose procurement requires a named counterparty and governing law

Watch out: The terms mention automatic renewal and service suspension for late payment, but name no contracting party and leave the governing law as an unfilled '[Jurisdiction]' placeholder, so there is no identifiable counterparty to escalate to.
