SOUND FAMILIAR?
What breaks when you call FLUX.1 schnell directly.
Same model, different reality once it's in production.
Failed generations
Provider returns 5xx. Generations fail mid-pipeline. Your users see errors and you pay for the retry.
Latency creep
schnell is supposed to be sub-second. Without warm capacity you wait through cold starts on every spike.
No fallback path
When your AI provider goes down, your pipeline goes down. No fallback.
Glue everywhere
Polling loops, retry logic, error handling. Every team rebuilds the same scaffolding.
Three steps. Zero failures.
Send your request
Same params as any other provider. Swap the endpoint, keep your code.
Auto-failover until it works
If a generation fails, we retry on our infrastructure. You never see the failure. You never pay for it.
Sentinel scores the output
Face fidelity, text accuracy, color, artifacts. Scores land in your dashboard so you know exactly what shipped.
Evaluate
See what you are actually shipping.
Every FLUX.1 schnell generation through Runflow is evaluated by Sentinel. You get quality insights on every output: what went well, what went wrong, and where to improve your prompts.

Catches bad inputs before you spend on a generation.
Every result graded against the checks that matter.
One ID ties the input, the score, and the retry together.
Improve quality and user experience at the same cost.
Sentinel scores every output on face fidelity, text accuracy, color match, and artifacts. Pick the mode that fits your pipeline.
Discard bad generations automatically.
Adds a few seconds. If a face, font, or score fails your threshold, the image is discarded and a fresh generation is triggered with the failure mode flagged.
Built for FLUX.1 schnell at scale.
Sub-second generation
schnell is distilled to 4 inference steps. We add zero overhead between the request and the model. Your users see images, not loading spinners.
Apache 2.0, no side agreement
FLUX.1 schnell is the only FLUX you can ship commercially without a license negotiation. Use it in your product immediately.
Automatic failover
When a generation fails, Runflow retries on our infrastructure. Your users never see an error.
Sentinel analytics included
Every output scored for face fidelity, text accuracy, color match, and artifacts. See your quality trends in a dashboard.
Same price as Black Forest Labs
Per-megapixel pricing mirrors BFL's published rate. Sentinel, dashboards, and auto-failover are included at no extra cost.
