SOUND FAMILIAR?

What breaks when you call Nano Banana directly.

Same model, different reality once it's in production.

Failed generations

Provider returns 5xx. Users see errors. You handle the failover and pay for the retry.

No quality visibility

Outputs drift over time. You can't tell which prompts perform. Bad images reach users before anyone notices.

Split observability

Volume, spend, latency, and quality each live in a different console. No single view.

Glue everywhere

Polling loops, retry logic, error handling. Every team rebuilds the same scaffolding.

HOW IT WORKS

Three steps. Zero failures.

Step 01

Send your request

Same params as any other provider. Swap the endpoint, keep your code.

Step 02

Auto-retry until it works

If a generation fails, we retry on our infrastructure. You never see the failure. You never pay for it.

Step 03

Sentinel scores the output

Face, text, style, artifacts. Scores land in your dashboard so you know exactly what shipped.

Evaluations

2,924

last 30 days

The total number of generations scored by Sentinel in this period.

Pass rate

89.53%

of all evaluations

The percentage of evaluations where all judges passed. Higher is better.

Avg score

0.91

out of 1.00

The average weighted score from 0 to 1 across all evaluations. Each judge contributes based on its configured weight.

Gate failures

20

0.7% of evaluations

Evaluations terminated early by a pre-check, for example no face detected or not-safe-for-work content. These never reached the full judge panel.

Failed judges

1,133

0.4 per evaluation

The total individual judge failures across all evaluations. One generation can fail multiple judges.

Regenerate rate

9.68%

lower is better

The percentage of evaluations where Sentinel recommended regeneration. Lower is better.

Input scoring

Catches bad inputs before you spend on a generation.

Output scoring

Every result graded against the checks that matter.

Trace on every call

One ID ties the input, the score, and the retry together.

ACT ON THE SCORE

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 outputs 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.
