FrameLite: Decision-Oriented Aesthetic Cropping with a Compact Vision-Language Model

Jianze Li, Kai Liu, Ziqing Zhang +4

Aesthetic image cropping improves composition by balancing subjects, context, and image boundaries. Large vision-language models bring semantic knowledge to this task, but their sc…

TwinPrune: Density-Aware Two-Phase Token Pruning for Vision-Language Models

Kai Liu, Anqi Li, Junxian Li +4

We propose a unified spatial-density signal to score token importance for both inference phases: bipartite merge for prefill and KV eviction for decode, yielding measurable gains i…

ET-Prune: Evidence-Aware Dynamic Budgeting for Visual Token Pruning in Text-Rich MLLMs

Zizhong Ding, Junxian Li, Kai Liu +4

Visual token pruning reduces the inference cost of multimodal large language models, but a fixed token ratio is poorly matched to text-rich inputs. In OCR-centric tasks, decisive e…

Macaron-V1: Towards Open Continual Learning with Self-Improvement and Mixture-of-LoRA

Mind Lab, :, Vin Bo +80

Macaron-V1 is an open agent-model family for experiential intelligence: learning from experience in real environments and continuing to learn after deployment. It is organized arou…

On the Scaling of PEFT: Towards Million Personal Models of Trillion Parameters

Mind Lab, :, Vin Bo +64

Parameter-efficient fine-tuning (PEFT) is usually treated as a cheaper alternative to full fine-tuning. We study a broader role: small trainable adapters as persistent local state…

PermuQuant: Lowering Per-Group Quantization Error by Reordering Channels for Diffusion Models

Yongsen Cheng, Kai Liu, Kaiwen Tao +5

Large-scale visual generative models have achieved remarkable performance. However, their high computational and memory costs make deployment challenging in resource-constrained sc…

MinT: Managed Infrastructure for Training and Serving Millions of LLMs

Mind Lab, :, Song Cao +60

We present MindLab Toolkit (MinT), a managed infrastructure system for Low-Rank Adaptation (LoRA) post-training and online serving. MinT targets a setting where many trained polici…

DRScaffold: Boosting Dense-Scene Reasoning in Lightweight Vision Language Models

Xinrui Shi, Kai Liu, Ziqing Zhang +3

Lightweight vision-language models perform competitively on standard benchmarks yet fail systematically in dense-scene reasoning, where multiple objects, attributes, and relations…

Accelerating Rectified Flow Models via Trajectory-Aware Caching

Xiao Liu, Kai Liu, Naiyang Guan +5

Diffusion and rectified flow (RF) models generate high-fidelity images and videos, but their iterative velocity-field evaluations are computationally expensive. Existing caching me…

GTR: Generation-Guided Visual Token Reduction for Separate-Encoder Unified Multimodal Models

Junxian Li, Kai Liu, Zizhong Ding +4

The development of separate-encoder Unified multimodal models (UMMs) comes with a rapidly growing inference cost due to dense visual token processing. In this paper, we focus on un…

PlanViz: Evaluating Planning-Oriented Image Generation and Editing for Computer-Use Tasks

Junxian Li, Kai Liu, Leyang Chen +7

Unified multimodal models (UMMs) have shown impressive capabilities in complex natural image generation. However, their potential in computer-use planning tasks, which are closely…
