VIF-Bench: Evaluating Visual Instruction Following in Multi-Reference Image Generation

VIF-Bench is introduced, a benchmark of 1,241 tasks designed to assess the edge of model capabilities in this joint setting in which multiple references must be composed under multiple and heterogeneous visual-instruction images, and uncover three findings.

Multi-Axis Max@K Reinforcement Learning for Representative Diversity in Text-to-Image Generation

This work formalizes target-mode coverage as target-mode coverage, the coverage of a predefined set of semantically specified modes, and proposes multi-axis max@K, a group-based reinforcement learning objective for improving it in diffusion-based T2I models.

SSM Meets Video Diffusion Models: Efficient Long-Term Video Generation with Structured State Spaces

The ablation study shows that when using SSMs for temporal modeling, incorporating bidirectionality and selective scans enhances video generation performance, and SSM-based models incur lower computational cost to achieve the same Fréchet Video Distance as attention-based models.
