Impact & Future
GenArena introduces a novel Elo-based benchmark for visual generation tasks, leveraging a pairwise scoring mechanism. This approach addresses the limitations of absolute pointwise scoring, which suffers from stochastic inconsistency and poor human alignment. By ensuring stable and human-aligned evaluation, GenArena provides a robust standard for model comparison.
A transformative finding is that simply adopting the pairwise protocol enables off-the-shelf open-source models to outperform top-tier proprietary models. Evaluation accuracy is boosted by over 20%, and a Spearman correlation of 0.86 with the authoritative LMArena leaderboard is achieved, drastically surpassing the 0.36 correlation of pointwise methods.
GenArena establishes a rigorous and automated evaluation standard for visual generation, allowing the community to benchmark state-of-the-art models across diverse tasks. This work contributes to democratizing AI research by demonstrating the effectiveness of open-source VLMs as judges in a pairwise paradigm, reducing reliance on costly proprietary models.

Global Elo Aggregation
| Feature | Pointwise Scoring | Pairwise Scoring (GenArena) |
|---|---|---|
| Evaluation Method | Absolute scalar scores | Relative comparison (binary choice) |
| Human Alignment | Poor (0.36 Spearman correlation) | Strong (0.86 Spearman correlation) |
| Self-Consistency | Low (prone to stochastic inconsistency) | High (stable judgments) |
| Discriminative Power | Limited (fails to distinguish subtle differences) | Enhanced (unlocks latent VLM capabilities) |
| Model Type Performance | Favors finetuned/proprietary models | Off-the-shelf open-source models can outperform |
Case Study: Qwen3-VL 8B Instruct
Using the GenArena framework, the off-the-shelf Qwen3-VL 8B Instruct model, when leveraging pairwise scoring, achieves state-of-the-art accuracy without any parameter updates. It demonstrates significant accuracy boosts: from 49.1% to 60.5% on GenAI-Bench (image generation), 58.3% to 83.7% on EditScore-Bench (image editing), and 57.0% to 61.5% on VideoGen-RewardBench (video generation). This highlights the power of the pairwise paradigm in unlocking the latent discriminative power of VLMs.
