pretty_name: Country Flag Variations (Flux 2-dev, image-verified)

Country Flag Variations (Flux 2-dev, image-verified)

Synthetic flag images generated with Flux 2-dev from the prompt "The national flag of {country}", then filtered by a strict image-to-image verification against official reference flags.

Dataset summary

  • 71 countries, 1395 images
  • Each country has 15-20 verified images (originally 20 per country; images that disagreed with the reference flag were removed)
  • Split: per-country 80 / 20 train/val (deterministic by sorted seed)
  • Image size: 1024 × 1024, PNG

Columns

column type description
country string Country name used in the source prompt
alpha2 string ISO 3166-1 alpha-2 code (e.g. US, AR, IL)
seed int64 Flux random seed
image Image 1024×1024 PNG
source_prompt string "The national flag of {country}"
description string Canonical description of the country's flag

Generation

Each image was produced by black-forest-labs/FLUX.2-dev with:

  • num_inference_steps=28
  • guidance_scale=4.0
  • height=width=1024
  • bfloat16 weights

Verification (image-to-image)

Every generated image was compared against the official reference flag of the same country using gemini-2.5-flash with both images in the context. The model returned YES only if:

  1. Correct colors (the main colors of the reference flag)
  2. Correct placement and order (stripes, quarters, hoist side)
  3. Correct major symbols — stars, crosses, emblems, crescents, shields: present when the reference has them; absent when it does not

These differences were explicitly ignored (and do not cause a NO): exact shade of color, fine interior detail of emblems, text legibility / spelling, aspect ratio, flat vs. waving vs. on-a-pole rendering, exact star count, proportions.

Images that returned NO were removed from the dataset.

Coverage

61 countries from the original 193-country attempt were excluded because fewer than 15 of their 20 Flux generations passed verification — typically countries whose flag contains a detailed central emblem or coat of arms that Flux does not render correctly.

Usage

from datasets import load_dataset

ds = load_dataset("tokeron/country-flags-variations")
sample = ds["train"][0]
sample["image"].save("example.png")
print(sample["country"], sample["seed"])
print(sample["description"])
