How It Works

Three steps to production.
No infrastructure required.

Step 01

Pick a Solution API

Choose the endpoint for your use case. Or request a custom one built on our infrastructure.

Step 02

Send your image

Standard REST call. We handle model selection, GPU routing, retries, and failover.

Step 03

Get verified output

Every image scored before and after delivery. Enable regeneration on bad quality images.

const response = await fetch(
"https://api.runflow.io/v1/models/run",
{
method: "POST",
headers: {
"Authorization": "Bearer YOUR_API_KEY",
"Content-Type": "application/json",
},
body: JSON.stringify({
model: "flux-2-dev",
prompt: "Minimalist tech setup",
}),
}
);
const data = await response.json();
console.log(data.url);

QUALITY EVALUATION

AI images break.
Choose how you catch it.

Every solution includes quality evaluation. Guard against bad outputs before delivery, score every image asynchronously, or get pipeline-level insights to optimize over time.

Discard bad images automatically.

Adds a few extra seconds to generation. Every image is evaluated before delivery. If it fails your quality thresholds, it's discarded and a new generation is triggered automatically with the specific issues flagged.

INFRASTRUCTURE

Built to handle your hardest day, not just your average one.

We invested years building the GPU infrastructure layer so you never have to. Peak traffic, GPU availability, model optimization: all handled.

Elastic GPU clusters

Thousands of GPUs scale up in seconds to match any traffic spike.

CUDA-optimized inference

Every model profiled, optimized, and matched to the right GPU.

Popular models stay warm

Top models are kept hot. No boot-up wait for common workloads.

Automatic failover

If a cluster is overloaded, traffic re-routes to the next available region.

CASE STUDY

AI Studio live in a week. 87% gross margin within a year.

BetterPic needed to ship a full AI headshot studio fast. With Runflow, they went from zero to production in a week, not months. No ML, Infra and AI engineers hired. No GPU infrastructure managed. Just a few API calls, all with automatic quality evaluation, failover, and retry.
