Compositional Text-to-Image Generation Via Region-aware Bimodal Direct Preference Optimization

CVPR 2026

Despite the rapid progress of text-to-image (T2I) models, generating images that accurately reflect complex compositional prompts (covering attribute bindings, object relationships, counting) still remains challenging. To address this, we propose BIDPO, a framework to enhance T2I model's capability

Unified Multimodal Autoregressive Modeling with Shared Context—Visual Tokenizer is Key to Unification

ICML 2026poster

Unified Multimodal Modeling aims to integrate visual understanding and generation within a single system. However, existing approaches typically rely on two disparate visual tokenizers, which splits the representation space and hinder truly unified modeling. We propose UniAR, a unified autoregressiv…

INST-IT: Boosting Instance Understanding via Explicit Visual Prompt Instruction Tuning

NeurIPS 2025poster

Large Multimodal Models (LMMs) have made significant breakthroughs with the advancement of instruction tuning. However, while existing models can understand images and videos at a holistic level, they still struggle with instance-level understanding that requires a more fine-grained comprehension an…

Synthesize Diagnose and Optimize: Towards Fine-Grained Vision-Language Understanding

CVPR 2024poster

Vision language models (VLM) have demonstrated remarkable performance across various downstream tasks. However understanding fine-grained visual-linguistic concepts such as attributes and inter-object relationships remains a significant challenge. While several benchmarks aim to evaluate VLMs in fin…
