Donatello AI Benchmark / Protocol & evidence

Image references: preserve what matters.

Eight reference tasks with separate checks for fidelity, identity, style and artifacts. No reference-quality ranking is available yet.

Published Version 2026-09-11-v1Operated by Donatello

Initial release: protocols and documentation estimates only. No comparative generation results, public votes or quality winners have been published.

Protocol status

8 cases × 3 planned attempts per model. No models have been enrolled and no attempts have been executed. For two models, the full eight-case reference set would require 48 attempts; this is a planning count, not a cost quote or observed sample.

Comparable settings must be locked before execution
Frame / target1:1 · 1024 × 1024; disclose unsupported sizes
Attempt allocationThree registered attempts per prompt and model, including technical failures
EnhancementOff where exposed; otherwise record provider default and place in a separate comparison stratum.
Outputs / winnerNot measured / no winner
Price / latency / failure rateNot measured—not zero

Inspect the reference input

Three cases reuse the same public synthetic vase. The five remaining cases must not run until their cleared references are registered. A face-preservation benchmark cannot be substituted with a vase test.

Benchmark input only: a blue ceramic vase on a white table

blue-vase · Reference, not a test result

Previously published first-party synthetic ceramic-vase image. Reused only as a disclosed benchmark input, never as a benchmark output.

A Donatello-origin reference may introduce source-domain bias. Add a rights-cleared independent source stratum before generalizing reference results. No real person's likeness is used.

Prompt set and required checks

Use the text exactly as published. The checks establish minimum task adherence; they are not an aesthetic score. A protocol amendment must not be optimized selectively after seeing one platform's output.
