Quality benchmark

Compare identical prompts across photorealism, text, dense composition, product consistency and controlled editing.

Publish every output, not only selected winners.
Use blind review where practical.
Separate subjective preference from instruction compliance.
2

Production benchmark

A better-looking image is not enough for a production switch. Measure operational behavior under the same workload.

Latency and timeout distribution.
Failure, moderation and refund rates.
Cost per usable output.
Reference preservation and batch consistency.
