V-RAE Uses Frozen Visual Representations as Video Latents, Converging Up to 6× Faster in K600 Generation Training

Instead of training a video VAE solely for pixel reconstruction, V-RAE adds temporal compression and a decoder on top of semantic features from models such as DINOv3, SigLIP2, and V-JEPA 2.1. The authors found that the new latents improve both generation and future-frame prediction, though they have so far demonstrated only low-resolution, short-clip, class-conditional generation.

RAGSieve Uses Retrieval Results as Its Own Baseline, Cutting RAG Poisoning Success from 67.4% to 14.0% with Two-Stage Filtering

RAGSieve requires neither a trusted corpus nor pre-labeled poisoned samples. Instead, it separately compares the tail of the query ranking and each document’s local semantic neighborhood. Open-source experiments cover three question-answering datasets, three retrievers, and six attacks, but a single fluent poisoned document and an already-compromised retrieval tail may still evade detection.

Mimir 1B Replaces Deep Stacking With Hierarchical Recurrence, Outperforms Tested 9B Models on Average Across Danish Benchmarks

The Danish Foundation Models team trained Mimir v1 from scratch, using HRM’s high- and low-level recurrent loops to approach some 4B models across the authors’ 20-benchmark evaluation. The weights are public, but “permissible data” does not mean fully open data: some corpora were used only under agreements or EU research exemptions.

“Test awareness” in the same set of models flips from positively to negatively correlated as prompts change, while the models themselves explain only 0.8% of the variance

A replication found that changing the probe’s contextual framing could shift the correlation with model scale from +0.94 to −0.82. The study recommends measuring across at least nine to ten prompt wrappers; otherwise, a single activation direction is insufficient for comparing models.

ReFind Skips Semantic Memory Indexes, Beats HippoRAG 2 by Five Points on Average Using Raw Chat-Log Search

ReFind preserves conversations without rewriting them, allowing an agent to repeatedly gather evidence using keyword, time, and session filters. Across roughly 2,800 test questions, it achieved an average accuracy of 58.2%, surpassing the strongest structured-memory baseline at 53.2%, though the comparison did not standardize all controllers and tool-call budgets.

DARTree Builds Trees in Batches Before Pruning, Accelerating Qwen3-4B Decoding to as Much as 9.73× the Speed of Local AR

DARTree extends causal correction for diffusion draft models from a single path to multiple branches and replaces node-by-node heap search with batched expansion by depth. In tests on a single RTX 6000 Ada, it delivered higher average speedups across seven tasks than DFlash, DDTree, and Domino, but the code has not yet been released.

TEMPO Assigns MoE Experts Based on Measured Runtime, Cutting Qwen3-235B p99 Token Latency by About 15.6%

Rather than balancing only tokens or the number of active experts, TEMPO estimates both HBM weight-loading costs and GEMM tile padding. An SGLang prototype improves throughput by 4% to 6% on some Qwen3-235B workloads, but adds only overhead on the communication-bound DeepSeek-V3.

Vero Pushes Coding Agents Across Entire Lean 4 Repositories; the Strongest Configuration Fully Solves Just 27 of 43 Tasks

Vero requires agents to implement multi-module software while submitting machine-verifiable correctness proofs, rather than merely passing unit tests. Across four frontier-agent configurations, the best still failed to fully solve 16 repositories, while 10 defeated every configuration.

OmniScientist Carries Multimodal Evidence Through the Research Workflow, With Direct Perception Winning 85% of Paired Evaluations

OmniScientist lets agents directly inspect images, signals, audio, video, 3D structures, and trajectories before completing ideation, experimentation, and paper writing. All 36 cases produced complete manuscripts, but the case count, code availability, and automated evaluation design still require clarification.

StateBridge Transmits Agents’ Hidden States via Closed-Form Alignment, Topping or Tying 22 of 26 Test Configurations

StateBridge uses an orthogonal Procrustes transformation to map the sending agent’s final-layer hidden states into the receiving agent’s input embedding space, without training a projector. Its average scores across four models exceeded the strongest baseline by 2.4 to 2.9 points, but it currently supports only agents using identical model weights.

FlashDrive Combines Caching, Speculative Decoding, and W4A8 to Cut 10B Autonomous-Driving VLA Latency to 151 Milliseconds

FlashDrive tackles four bottlenecks—visual encoding, LLM prefill, reasoning tokens, and trajectory denoising—cutting Alpamayo 1.5-10B single-window latency on an RTX PRO 6000 from 717 to 151 milliseconds. The open-source implementation approaches real-time inference, but requires specialized fine-tuning, and its closed-loop evaluation covers only 100 simulated clips.

AlayaWorld v1.1 Switches to a Streaming 3D Point Cache, Raising Its Long-Horizon Video Consistency Score to 89.5

AlayaWorld has rewritten the spatial memory and conditioning pipeline of its interactive world model so that camera controls, historical frames, and generated content use aligned causal VAE representations. A new report claims the highest overall consistency score on WBench, but the updated weights and inference code have yet to be released.
