DeepAlign: Mitigating Modality Conflict through Modality-Specific Alignment

CVPR 2026

Multimodal Large Language Models (MLLMs) have demonstrated promising advancements in augmenting the capabilities of LLMs to comprehend visual input. However, modality misalignment between vision and text remains a key challenge in MLLM, which can be attributed to two aspects: misalignment of modalit

Evolving Generalist Virtual Agents with Generative and Associative Memory

AAAI 2026technical

Generalist Virtual Agents (GVAs) powered by Multimodal Large Language Models (MLLMs) exhibit impressive capabilities. However, their long-term learning is hampered by a core limitation: a failure to evolve beyond existing trajectories. This stems from memory systems that treat experiences as isolate

FineFocus: Benchmarking and Improving Fine-Grained Text-to-Image Alignment via Paired Reinforcement Learning

ICML 2026poster

While recent autoregressive models have achieved text-to-image generation performance comparable to diffusion models, they significantly struggle with fine-grained semantic alignment. To rigorously evaluate this limitation, we introduce DeltaBench, a benchmark featuring paired prompts with subtle fi…

SCOPE: Evolving Symbolic World for Planning in Open-Ended Environments

ICML 2026poster

Recent works have explored integrating Vision-Language Models (VLMs) with classical planners that rely on symbolic representations of planning problem to generate long-horizon plans for complex embodied tasks. However, in open-ended environments, these symbolic representations obtained from percepti…

Janus-Pro-R1: Advancing Collaborative Visual Comprehension and Generation via Reinforcement Learning

NeurIPS 2025poster

Recent endeavors in Multimodal Large Language Models (MLLMs) aim to unify visual comprehension and generation. However, these two capabilities remain largely independent, as if they are two separate functions encapsulated within the same model. Consequently, visual comprehension does not enhance vis…
