R3-Bench: Reason-Reflect-Rectify Benchmark
Code: github.com/xiaomoguhz/R3-Bench Paper: Benchmarking and Evolving Reason-Reflect-Rectify for Reflective Visual Generation — accepted to ICML 2026.
R³-Bench evaluates reflective visual generation: given a generated image and the original prompt, a model must (i) reason about whether the image matches the prompt, (ii) explain any discrepancy, and (iii) propose a rectification action. The benchmark measures two complementary scores:
- S_ref — Reflective Verdict Score (verdict + explanation correctness, judged by an LLM)
- S_rect — Rectification Score (normalised VQA-alignment gain after applying the proposed edit)
Contents
| File | Description |
|---|---|
images.tar.gz |
670 source images (PNG, ~717 MB), organised as images/{category}/{verdict}/r3b_{idx:06d}.png |
The 670-sample prompt + ground-truth JSONL ships with the code repository at r3bench/data/r3bench.jsonl — labels travel with the eval code so version drift is captured by git.
Schema
Each JSONL record:
{
"idx": 0,
"original_prompt": "a black candle and a white holder",
"bad_image": "images/color/false/r3b_000000.png",
"answer": false,
"explanation": "The white object is a candle, not a holder as specified in the prompt.",
"category": "color",
"generated_qa": {
"yn_question_list": ["Is there a candle in the image?", "..."]
}
}
| Field | Type | Description |
|---|---|---|
idx |
int | Unique sample id (0–669) |
original_prompt |
str | The text-to-image prompt |
bad_image |
str | Image path relative to the data root |
answer |
bool | Ground-truth verdict: does the image match the prompt? (false = mismatch) |
explanation |
str | Ground-truth discrepancy description (used as S_ref reference) |
category |
str | Error dimension: color · object · numeracy · spatial · shape · texture · complex · non |
generated_qa.yn_question_list |
list[str] | Yes/no VQA probes used by the S_rect rectification scorer |
Category & verdict distribution (670 total)
| Category | false (mismatch) | true (match) | Total |
|---|---|---|---|
| color | 71 | 26 | 97 |
| complex | 46 | 48 | 94 |
| non | 7 | 42 | 49 |
| numeracy | 73 | 23 | 96 |
| object | 54 | 17 | 71 |
| shape | 72 | 20 | 92 |
| spatial | 76 | 25 | 101 |
| texture | 49 | 21 | 70 |
| Sum | 448 | 222 | 670 |
non = "no error" probe samples (image matches prompt) used to calibrate false-positive reflection.
Usage
# 1. Download images
hf download xiaomoguhzz/R3-Bench-data images.tar.gz \
--repo-type dataset --local-dir /path/to/r3bench-data
cd /path/to/r3bench-data && tar -xzf images.tar.gz
# → /path/to/r3bench-data/images/{category}/{true,false}/r3b_{idx:06d}.png
# 2. Run the 4-step pipeline (clone the code repo first)
git clone https://github.com/xiaomoguhz/R3-Bench && cd R3-Bench
export R3BENCH_DATA_DIR=/path/to/r3bench-data
bash scripts/run_reflection.sh 8 qwen2.5vl # Step 1 — reflection
bash scripts/run_edit.sh 8 qwen2.5vl qwen_image_2511 # Step 2 — editing
bash scripts/eval_reflection.sh qwen2.5vl # Step 3 — S_ref
bash scripts/eval_edit.sh qwen2.5vl qwen_image_2511 # Step 4 — S_rect
See the code repo README for full pipeline details, supported backends, and how to plug in a custom reflection / editor model.
