VoT: Vision-of-Thought for Unified Multimodal Representation Alignment

The paper introduces Vision-of-Thought (VoT), a framework that inserts a discrete visual-thinking layer between vision‑language models (VLMs) and diffusion transformers (DiTs). Instead of using VLMs solely as text encoders, they act as multimodal planners that generate VoT tokens—high‑level visual plans such as objects and layouts—before pixel rendering. A specialized VoT tokenizer is trained with a closed‑loop objective combining VLM alignment, feature reconstruction, and vector‑quantization losses, ensuring the tokens are semantically readable by the VLM while preserving necessary visual information. Experimental results show that VoT improves semantic alignment and offers a structured, interpretable interface for controllable generation.

Bernini: Latent Semantic Planning for Video Diffusion

Bernini proposes a unified framework that separates semantic planning and pixel rendering for video generation and editing. An MLLM-based planner predicts target semantics in ViT embedding space, while a DiT-based renderer synthesizes pixels conditioned on this plan, text features, and source VAE features for editing. The approach introduces Segment-Aware 3D Rotary Positional Embedding and chain-of-thought reasoning, achieving state‑of‑the‑art performance on diverse video benchmarks.

VIVAS: Vitalizing Visual Perception in VLM Pre-training via Vision-language Unified Autoregressive Supervision

VIVAS is a new Vision‑Language Model pre‑training framework that addresses the lack of fine‑grained visual perception in existing VLMs. It introduces a unified token space and a dense‑structural‑semantic vision tokenizer that expands the textual vocabulary with visual tokens, enabling vision‑language unified autoregressive supervision over both visual details and linguistic content. Trained on 12.4 T tokens, VIVAS achieves state‑of‑the‑art results on 7 tasks and 39 multimodal benchmarks.

QK-Edit: Revisiting Attention-based Injection in MM-DiT for Image and Video Editing

QK-Edit introduces a training‑free query‑key manipulation strategy for Multimodal Diffusion Transformers (MM‑DiTs), enabling precise text‑guided image and video editing. By isolating and adjusting critical attention components, it balances prompt fidelity with structural consistency, supporting tasks such as object addition, removal, replacement, background changes, material and color adjustments, and style transformation. The method works seamlessly with state‑of‑the‑art models like FLUX and HunyuanVideo, improving editing performance without requiring additional training.
