GenAI Asset Evaluation Benchmark

A reusable framework for judging whether generated images and video are ready to ship for licensed products: a real photo as the answer key, one locked input, and eight criteria scored side by side.

Overview

New image and video models ship every few weeks, each promising better quality. For licensed products, better has a narrow meaning: the logo, the numbers, the material and the color have to match the licensed art exactly. The team needed one consistent way to tell whether a new model or platform actually moves production forward.

New models, same test

Every model that ships, whether Nano Banana, Seedream, Image 2.0, Wan or whatever comes next, runs through the same framework, so improvements are measured rather than assumed.

Different platforms, same bar

Each platform's own generative tooling, such as Figma Weave and Flora, is judged on the same quality bar, not just the model underneath.

Test Method

The same four steps apply to every test case. The first two are built once; for each new model, only the last two run again.

  1. 1Gold ShotA real, physically shot photo: the answer key everything is measured against.
  2. 2Standard inputFixed reference images and one locked prompt, never rewritten mid-test.
  3. 3Benchmark runEvery model or platform gets the same inputs, with no adjustments mid-run.
  4. 4Score & compareEach output is scored on the criteria, side by side with the Gold Shot.
Built onceRe-run for each new model

Six Test Cases

The cases cover the work the team ships most: headwear macro shots, on-model photography, hollow-body swaps, floating jerseys, multi-step marketing images and on-model video.

Test cases overview

Evaluation Criteria

Every output is compared to the art file on eight criteria; video adds a ninth for motion.

Identity
#1Logos / TextName, number and logo design are correct, with accurate font and spacing.
#2Logo / Text CountEvery required patch, logo and text element is present, in the right quantity.
Material
#3Garment TextureFabric texture, weave and sheen match the correct material.
#4Patch / Logo TextureEmbroidery or print looks accurate, not flat or generic.
#5ColorColor matches the Pantone reference, with no shift between batches.
Construction
#6Structure & PlacementShape, seams, tag and logo placement match the real construction.
#7Garment RealismThe image reads as a photograph, with correct lighting, shadow and drape.
Verdict
#8Output ReadinessTakes the lowest of the seven scores, so one blocking flaw can't hide behind strong ones.
#9MotionVideo only: free of flicker, physically believable and smooth.

High-Risk Zones

For each case I mapped where AI output most often goes wrong, so review time goes to the places that matter: logo placement and embroidery, snap counts, numeral fonts, invented sleeve logos, letter spacing, seams and jock tags.

Headwear front high-risk zones
Headwear, front: material, logo position, embroidery, brim trim
Headwear back high-risk zones
Headwear, back: snap color and count, interior mesh, wordmark
On-model front high-risk zones
On-model, front: league shield, wordmark, numeral stitching and font
On-model back high-risk zones
On-model, back: invented sleeve logos, shoulder numeral, nameplate, extra seams
Floating jersey zoom-in check
Floating jersey: letter spacing, seam transition, jock tag

Scored Results

Each output is scored against the art file, with flagged regions numbered to the criterion they fail and a note on how each was fixed.

Insights

  • Hollow-body swaps passed every criterion: the garment image carries its own graphics, so there is little for the model to invent.
  • Type is the weakest point. Numerals, wordmarks and small text such as jock tags usually need several regenerations or a Photoshop fix.
  • Models add detail that isn't there, such as extra sleeve logos, seams and panels, so absence has to be checked as carefully as presence.
  • Construction details like snap counts drift between runs, and color often needs a manual correction.
  • Scoring readiness by the lowest criterion keeps a single blocking flaw from hiding behind otherwise strong results.

Impact

The benchmark gives the team a shared bar for adopting new models and platforms. Evaluating a new release now means re-running two steps instead of starting over, and the same high-risk zones guide everyday review of production work.
