WorldCraft lets you click an object and drag its path inside a camera-controlled video world model. It hits 38.90px trajectory error vs DragAnything's 39.86 and keeps camera RPE at 0.131 via world-space paths and a LoRA.
MemDreamer turns hours-long video QA into agentic retrieval over a 3-tier graph memory, lifting LVBench from 78.2 to 90.7 (+12.5) while the reasoning model reads ~6K tokens instead of 240K-784K.
Robust-U1 trains an MLLM to reconstruct corrupted visual content, reaching 0.7398 overall on R-Bench versus 0.5770 for BAGEL and 0.5017 for Robust-R1.
StreamMA pipes each reasoning step to the next agent the moment it is written, not after the full chain. Across 8 benchmarks it gains +7.3 pp on average (max +22.4 pp on HMMT 2026) and runs up to 26.9x faster.
Echo-Infinity is an autoregressive video model with a learnable evolving memory that compresses any-length history at constant cost, hitting 24-hour rollouts (over 1.3M frames) in real time at 18.5 FPS on an H100.
Fine-Tuning & Adaptation · HKUST
On-policy distillation does not sit between SFT and RLVR — it carves its own geometry. Its updates touch fewer weights, avoid principal directions, and lock into a narrow low-dimensional subspace early in training.
