+# Gen-Arena
+
+Gen-Arena is a text-to-image evaluation benchmark for compositional prompt following and reference-conditioned generation. Each sample contains a natural-language generation prompt, optional reference images, named entities, and fine-grained constraints.
+
+Gen-Arena is introduced in the paper *SCOPE: Structured Decomposition and Conditional Skill Orchestration for Complex Image Generation* as a human-annotated benchmark with entity- and constraint-level specifications.
+
+This package contains 300 samples across 6 categories:
+
+| Category | Samples | Unique image files | Reference slots |
+| --- | ---: | ---: | ---: |
+| `1-cartoon` | 50 | 56 | 56 |
+| `2-game` | 50 | 103 | 104 |
+| `3-sports` | 50 | 50 | 50 |
+| `4-entertainment` | 50 | 50 | 50 |
+| `5-competition` | 50 | 0 | 0 |
+| `6-ceremony` | 50 | 30 | 50 |
+
+## Files
+
+- `data/gen_arena.jsonl`: unified metadata file with all 300 samples.
+- `reference_images/<category>/`: reference images grouped by category.
+
+All image paths in `data/gen_arena.jsonl` are root-relative paths.
+
+## Schema
+
+Each row in `data/gen_arena.jsonl` has the following fields:
+
+- `id`: unique sample id.
+- `category`: category directory name.
+- `prompt`: generation prompt.
+- `reference_images`: list of objects with `id` and root-relative `path`.
+- `reference_image_paths`: list of root-relative image paths.
+- `num_reference_images`: number of reference images for the sample.
+- `entities`: list of named entities and optional reference links.
+- `constraints`: list of fine-grained constraints with `id`, `type`, `text`, and `depends_on`.
+- `num_entities`: entity count.
+- `num_constraints`: constraint count.
+- `constraint_type_counts`: counts by constraint type.
+
+Constraint types are `attribute`, `layout`, and `relation`.
+
+## Loading
+
+```python
+from datasets import load_dataset
+
+dataset = load_dataset("json", data_files="data/gen_arena.jsonl", split="train")
+print(dataset[0]["prompt"])
+print(dataset[0]["reference_image_paths"])
+```
+
+Reference images can be loaded by joining each `reference_image_paths` value with the dataset root. For example, image paths follow the form `reference_images/1-cartoon/1-cartoon_001_Tiggy.jpg`.
+
+## Notes
+
+- `5-competition` is intentionally text-only and has no reference images.
+- Some samples share the same reference image file after exact duplicate cleanup.
+- The license and redistribution status of reference images should be verified before public release.
+
