SOUND FAMILIAR?
What breaks when you call FLUX.2 dev 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.
Reference image chaos
Multi-reference workflows need orchestration. Without it, prompts drift, references collide, outputs feel stitched.
No fallback path
When your AI provider goes down, your pipeline goes down. No fallback.
JSON prompt glue
FLUX.2's JSON prompting needs schema validation. Every team rebuilds the same input contract.
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
Reference adherence, text accuracy, color, artifacts. Scores land in your dashboard so you know exactly what shipped.
Evaluate
See what you are actually shipping.
Every FLUX.2 dev 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 reference adherence, text accuracy, color match, and artifacts. Pick the mode that fits your pipeline.
Discard bad generations automatically.
Adds a few seconds. If reference adherence drops, text breaks, or the score is low, the output is discarded and a fresh generation is triggered with the failure mode flagged.
Built for FLUX.2 dev at scale.
10 reference images per call
FLUX.2 dev accepts up to 10 references in a single request. Use it for multi-product shots, style blends, or character consistency without chaining calls.
Automatic failover
When a generation fails, Runflow retries on our infrastructure. Your users never see an error.
JSON prompting with schema validation
FLUX.2's structured prompt format validated at the edge. Wrong shape returns a typed error instead of a wasted generation.
Sentinel analytics included
Every output scored for reference adherence, 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.
