We propose MegaStyle, a novel and scalable data curation pipeline that first explores consistent T2I style mapping ability from current large generative models to construct intra-style consistent, inter-style diverse and high-quality style dataset.
The paper provides concrete evidence for the MegaStyle pipeline: Section 3.1 (p_10-p_11) describes the three-stage pipeline in detail, Figure 2(c) demonstrates the consistent T2I style mapping capability, Table 1 compares MegaStyle-1.4M with existing

We construct a diverse and balanced prompt gallery containing 170K style prompts and 400K content prompts, yielding up to 68B content-style combinations for training, and we use these prompts to generate the MegaStyle-1.4M dataset.
This is a factual claim with specific numbers that are stated clearly in the paper. p_11 states 'This process yields 170K style prompts and 400K content prompts.' The 68B combinations (170K × 400K) is a straightforward calculation. The paper confirms

We apply the paired supervision to train a Diffusion Transformer (DiT)-based model FLUX, resulting in MegaStyle-FLUX, which supports generalizable and stable style transfer.
The paper shows MegaStyle-FLUX training on MegaStyle-1.4M and provides quantitative comparisons (Tables 3, 6, 7) and qualitative results (Figures 9, 18-23). However, 'generalizable' and 'stable' are not quantified - there's no explicit test of genera

The style image pool contains 2M images, including about 1M images from a large-scale deduplicated stylized-image corpus, 80K images from WikiArt covering diverse real-world painting styles, and about 1M additional stylized images filtered from public image collections using style descriptors derived from WikiArt.

Our MegaStyle-Encoder achieves substantially higher mAP and Recall scores than all other methods across all backbones, with a large margin.
Strong quantitative evidence from Table 2. For ViT-B backbone: MegaStyle-Encoder achieves mAP@1=85.8, Recall@1=89.2, mAP@10=70.4, Recall@10=98.4, compared to next best SigLIP at 66.7, 71.2, 51.8, 93.4 respectively. Similar substantial margins for ViT

For a given query style image, the most similar image retrieved by SigLIP is often biased toward semantic content rather than style.
Qualitative evidence from Figure 8 shows SigLIP retrieving images with matching content (butterfly, house with tree, sailboat) rather than matching style. This is visual qualitative evidence rather than quantitative measurement.

CSD performs better than SigLIP, but it still relies on content cues for style matching. We attribute this to the coarse style labels in its training dataset, where style pairs within a style may share similar content and exhibit intra-style discrepancy.
The first part (CSD performs better than SigLIP) is supported by Table 2 quantitative results. The second part (relies on content cues) has qualitative evidence from Figure 8. However, the attribution to 'coarse style labels in its training dataset'

Since they were trained on a dataset with limited styles, CSGO, DEADiff, and StyleCrafter exhibit the poor performance on these styles, often transferring only the basic colors from the reference style images.
The observation about poor performance and basic color transfer is supported by visual evidence in Figure 9. However, the causal attribution ('Since they were trained on a dataset with limited styles') is a hypothesis not directly tested. No controll

局限性（作者自述）
- The generalization ability of current VLMs is limited, making it difficult for them to recognize uncommon styles.
- Qwen-Image shows association bias toward some styles in the image generation process. When the style prompt includes 'Japanese painting,' the generated objects are often depicted as Japanese figures biased toward historical periods such as the Edo or Meiji era (e.g., kimono/yukata, traditional hairstyles, and scroll-painting-like or ancient-architecture backgrounds).
- Some loss of stylistic detail is inevitable during reproduction when generating style images from captioned style prompts.
