Q-ReAlign — Pro (9B)
Lightweight, human-aligned multimodal quality judge built on a modern Qwen3.5 vision-language backbone.
Q-Align-level performance with roughly half the parameters — the largest, highest-fidelity variant of the family.
GitHub · Method · Adapting guide · Mini (0.8B) · Lite (4B) · Pro (9B)
What this is
Q-ReAlign scores the perceptual quality / aesthetic appeal of an image or video the way Q-Align does: the model is asked to rate quality, and the probability mass it places on the discrete words excellent / good / fair / poor / bad is collapsed — via a fixed weighting [1.0, 0.75, 0.5, 0.25, 0.0] — into a single scalar in [0, 1].
Pro (9B) is the flagship of three sizes (Mini 0.8B · Lite 4B · Pro 9B). All three match or beat the original Q-Align across seven QA benchmarks; quality scales cleanly with size, and Pro sits at the top.
- Backbone: Qwen3.5-VL (
model_type: qwen3_5), hybrid linear/full attention text tower + SigLIP-style vision encoder - Tasks: IQA (image quality) · IAA (image aesthetics) · VQA (video quality) — the unified ONE-ALIGN setting
- Training: full-parameter SFT in bf16 via ms-swift, vision tower + projector trainable
- Precision: bfloat16 · dtype
auto
Results
Per-dataset SRCC / PLCC on seven QA benchmarks. Pro (9B) reaches avg SRCC 0.896 vs. Q-Align's 0.869.

Each cell is SRCC / PLCC. Numbers are the full evaluation sets (KonIQ, SPAQ, KADID, AGI, LIVE, AVA, LSVQ).
Quick start
import torch
from PIL import Image
from transformers import AutoModelForImageTextToText, AutoProcessor
# transformers >= 5.2.0 for Qwen3.5 support
CKPT, IMAGE = "q-future/Q-ReAlign-Pro-9B", "photo.jpg"
LEVELS = ["excellent", "good", "fair", "poor", "bad"]
WEIGHTS = [1.0, 0.75, 0.5, 0.25, 0.0]
device = "cuda" if torch.cuda.is_available() else "cpu"
processor = AutoProcessor.from_pretrained(CKPT)
model = AutoModelForImageTextToText.from_pretrained(CKPT, dtype="auto").to(device).eval()
messages = [{"role": "user", "content": [
{"type": "image"},
{"type": "text", "text": "How would you rate the quality of this image?"},
]}]
text = processor.apply_chat_template(messages, add_generation_prompt=True) + "The quality of the image is"
inputs = processor(text=[text], images=[Image.open(IMAGE).convert("RGB")], return_tensors="pt").to(device)
ids = [processor.tokenizer(" " + w, add_special_tokens=False).input_ids[0] for w in LEVELS]
probs = model(**inputs).logits[0, -1, ids].softmax(-1)
score = (probs * torch.tensor(WEIGHTS, device=device)).sum().item()
print(f"quality score: {score:.4f}") # 0 (worst) .. 1 (best)
The score is the expected value of the level weights under the model's next-token distribution over the five level words — no sampling, one forward pass.
Aesthetics or video
Swap the prompt for the task:
- Aesthetics (IAA): "How would you rate the aesthetics of this image?" → stem "The aesthetics of the image is"
- Video (VQA): sample N frames (default 8) and pass them as the image sequence; prompt "How would you rate the quality of this video?" → stem "The quality of the video is"

Scoring contract
- Level vocabulary:
excellent, good, fair, poor, bad - Weights:
[1.0, 0.75, 0.5, 0.25, 0.0] - Output: scalar in
[0, 1], higher = better - The five level tokens are matched with a leading space (
" excellent", …); keep that when porting to other tokenizers.
Intended use & limitations
- Use: no-reference image/video quality assessment, aesthetic scoring, dataset curation, ranking and filtering generated media, reward signals for generative pipelines.
- Out of scope: safety/content moderation, factual or identity judgments, medical/forensic grading. Quality is perceptual and dataset-conditioned.
- Scores are calibrated to the training MOS distribution; absolute values are most meaningful relative to one another. Re-calibrate before mixing with other scales.
