Synexa
Synexa is a generative media platform for developers who need hosted inference on diffusion and multimodal models. Its Explore catalog lists dozens of ready-to-run APIs across text-to-image, image-to-video, text-to-video, image-to-3d, audio, and utility workflows, including FLUX, Stable Diffusion XL, Hunyuan 3D, Veo 3.1, and Wan 2.2.
The product centers on production APIs and interactive playgrounds rather than a single end-user app. Docs describe serverless deployment for custom models, enterprise options like private models and preference fine-tuning, and SDKs for Python and Node.js that authenticate with API keys.
Pricing is usage-based. The pricing page bills per model output for hosted models and per second for GPU hardware, with rates positioned below Replicate and Fal.ai on comparable H100 and A100 tiers. When nothing is running, compute scales to zero.
It fits engineering teams shipping generative images, video, 3D assets, or audio into products and wanting one integration surface instead of wiring each model vendor separately.
Browse 33+ hosted models for images, video, 3D, audio, and utility tasks in one Explore catalog
FLUX Schnell generations start at $0.0015 per image on the public pricing table
GPU compute is billed by the second and scales to zero when workloads are idle
Official Python and Node.js clients with a quickstart that runs FLUX Schnell in one API call
Serverless custom model deployment plus UI playgrounds for testing before production use
Large Explore catalog covers images, video, 3D, audio, and utility models behind one API surface.
Published per-model and per-GPU rates make usage costs easy to compare before integration.
Official Python and Node.js quickstarts show a working FLUX Schnell call with minimal setup.
Hardware billing scales to zero when models are not running, which suits bursty workloads.
The homepage can throw a client-side application error in headless fetches, so marketing copy is harder to scrape than docs or pricing.
Pricing is entirely usage-based, so teams need to monitor per-second GPU spend for long-running jobs.
No mobile app; Synexa is an API and web dashboard product for developers.
What kinds of models does Synexa host?
Synexa hosts generative models across text-to-image, image-to-image, image-to-video, text-to-video, image-to-3d, text-to-audio, video-to-audio, super-resolution, and utility tasks. The Explore page lists models such as FLUX Schnell, Stable Diffusion XL, Hunyuan 3D, Veo 3.1, and Suno.
How does Synexa pricing work?
Synexa charges per model output for hosted APIs and per second for GPU hardware. The pricing page lists per-image rates for models like FLUX Schnell at $0.0015 and per-second rates for GPUs such as NVIDIA H100 at $0.00083 per second ($2.99 per hour).
Does Synexa provide official SDKs?
Yes. Synexa documents Python and Node.js clients. The quickstart shows installing the synexa package, setting an API key, and calling black-forest-labs/flux-schnell with a text prompt.
Can I deploy custom models on Synexa?
Yes. Synexa docs list serverless deployment options for custom models, along with interactive UI playgrounds for experimentation before production integration.
What GPU hardware does Synexa offer?
Synexa publishes hardware pricing for NVIDIA H100, A100 (80GB), A6000, RTX 4090, and RTX 3090 GPUs. Rates are billed by the second and include specs for GPU count, CPU, GPU RAM, and system RAM on the pricing page.
How do I authenticate Synexa API requests?
Synexa requires an API key. The quickstart shows creating a key and passing it through the SYNEXA_API_KEY environment variable or directly when initializing the Python or Node.js client.
