# 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`](https://huggingface.co/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

```python
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"])
```
