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.

CPPO replaces PPO's one-size threshold with stricter early-token clipping and a running prefix-divergence budget, lifting Qwen3-30B-A3B-Base AIME from 49.23 (DPPO) to 54.79.

Flow-DPPO swaps PPO ratio clipping for an exact per-step Gaussian KL term, lifting GenEval2 to 48.1 on SD3.5 (vs 39.9 for Flow-GRPO) while cutting policy drift roughly 4x.
A Tencent YouTu Lab survey maps the chatbot-to-agent shift on two axes: cognitive core (Chatbot then Thinking LLM) and task execution (Agent then Workspace plus Skill), arguing persistent state is the real leap.

DRPO swaps DPPO's hard divergence mask for a smooth advantage-weighted quadratic regularizer, keeping the Binary-TV trust region but with bounded gradient weights, and trains Qwen3 LLMs more stably under FP8.
Multimodal Models · Nanjing University
HYDRA-X unifies image and video tokenization in one ViT; tubelet attention and hierarchical temporal patchify improve DAVIS rFVD to 11.19 and editing overall to 4.34.
Mixture of Experts · Renmin University of China
MPI redesigns MoE routers by aligning router rows with expert weight directions. On 11B MoE, average benchmark accuracy rises from 40.92 to 42.76 with only 0.2% training slowdown.
FlashMemory-DeepSeek-V4 keeps only the KV chunks a neural indexer predicts you will need, shrinking physical KV cache to 13.5% of full-context decoding while accuracy stays flat or edges up ~0.6%.
