AI总结:

MoI-Bench是面向移动设备图像生成与编辑的基准测试集,通过“操作×目标”设计及MoI-Eval评估方法,揭示端侧模型的能力差距,为模型改进提供细粒度指导。

摘要:

开发端侧图像模型需要考虑实际用户需求、任务类型及设备资源约束。然而,现有基准测试集在识别端侧模型与服务器端模型的能力差距方面提供的指导有限。我们推出MoI-Bench,这一基准测试集基于移动用户需求构建,包含64个子任务和1150个样本。它定义了16种操作(如移除、替换)以及8个视觉目标类别(涵盖人像、文字等内容),这些构成两个正交轴,其适用组合定义了特定任务,例如移除面部妆容。为更好地指导模型改进,我们进一步提出MoI-Eval,引入了针对特定任务的评估标准,涵盖指令遵循、视觉质量和细节保留。我们还构建了样本级评估问题,并将其分数聚合为沿操作、目标和标准轴的整体质量与能力轮廓。我们评估了代表性的端侧与服务器端模型,并测量了移动部署成本。结果表明,这种解耦的“操作×目标”设计为改进紧凑模型提供了更细粒度的指导,例如,它强调需优先解决特定能力差距(如文字替换),而非宽泛的应用级目标(如改进文字编辑)。与使用单一分数对模型排名的传统基准不同,我们引入了二维“质量-可部署性”能力图来评估模型的实际移动适用性。该图显示,当前端侧模型可实现高效生成或编辑,但扩大其任务覆盖范围比进一步提升部署效率更值得关注。进一步的进展需要提升编辑质量,尤其是身份保留和文字渲染能力,同时拓宽任务覆盖范围。

英文摘要:

Developing on-device image models requires considering practical user needs, task types and device resource constraints. However, existing benchmarks provide limited guidance on identifying capability gaps between on-device models and server-side models. We introduce MoI-Bench, a benchmark grounded in mobile user needs, comprising 64 subtasks and 1150 samples. It defines 16 operations, such as removal and replacement, and eight visual target categories covering content such as portraits and text. These form two orthogonal axes whose applicable combinations define specific tasks, such as removing facial makeup. To better guide model improvement, we further propose MoI-Eval, which introduces task-specific criteria covering instruction following, visual quality and detail preservation. We further construct sample-level evaluation questions and aggregate their scores into overall quality and capability profiles along the operation, target and criteria axes. We evaluate representative on-device and server-side models and measure mobile deployment costs. Results show that this decoupled Operation x Target design provides finer-grained guidance for improving compact models. For example, it highlights the need to prioritize specific capability gaps (e.g., text-replacement) over broad application-level goals (e.g., improving text editing). Unlike conventional benchmarks that rank models using a single score, we introduce a two-dimensional Quality-Deployability capability map to assess models for practical mobile use. The map shows that current on-device models can achieve efficient generation or editing but expanding their task coverage deserves greater attention than further improving deployment efficiency. Further progress requires improving editing quality, particularly identity preservation and text rendering, while broadening task coverage.
