The most reliable FLUX Kontext API,scored on every output.
Reliable image editing with auto-failover. Every edit scored for identity preservation. Same per-image price as Black Forest Labs. We build the integration and run it in production.
SOUND FAMILIAR?
What breaks when you call FLUX Kontext directly.
Same model, different reality once it's in production.
Failed edits
Provider returns 5xx. Edits fail mid-pipeline. Your users see errors and you pay for the retry.
Identity drift across turns
Multi-turn edits shift the face, the product, or the brand. You can't catch it before users do.
Single-provider risk
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 an edit fails, we retry on our infrastructure. You never see the failure. You never pay for it.
Sentinel scores the edit
Identity preservation, edit precision, artifacts. Scores land in your dashboard so you know exactly what shipped.
Evaluate
See what you are actually shipping.
Every FLUX Kontext 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 edit on identity preservation, edit precision, color match, and artifacts. Pick the mode that fits your pipeline.
Discard bad edits automatically.
Adds a few seconds. If identity drifts, the edit precision fails your threshold, or the score is low, the output is discarded and a fresh edit is triggered with the failure mode flagged.
Built for FLUX Kontext at scale.
Automatic failover
When an edit fails, Runflow retries on our infrastructure. Your users never see an error.
Sentinel analytics included
Every edit scored for identity preservation, edit precision, color match, and more. See your quality trends in a dashboard.
Know what you are shipping
At scale, nobody reviews every edit. Sentinel does. Get per-dimension scores and actionable insights on every batch.
