TsuGO Reconstructs Search Trees from Reasoning Text; Gemini 3.1 Pro Scores Just 19% on Open-Ended Hard Problems

Using 600 verifiable Go life-and-death problems, TsuGO measures whether models allocate reasoning resources to the correct branches rather than merely counting correct answers and tokens. After four multiple-choice candidates are removed, both accuracy and search efficiency fall sharply across several reasoning models, leaving a clear gap with the neural-network-guided KataGo.

Post-Norm Beats Pre-Norm During Progressive Transformer Depth Growth, Cutting CE by 0.0328 in a 9-Layer Student Model

A Qwen3-8B distillation experiment found almost no difference between the two normalization placements when training the full depth jointly, but Post-Norm clearly outperformed after Transformer blocks were added in stages. The results show that normalization placement should not be chosen independently of the model growth strategy.

AI Code Reviews Drive More Than 400 Fixes into Linux 7.2-rc7, Shifting the Maintainer Bottleneck to Human Triage

Late in the Linux 7.2-rc7 release cycle, more than 230 contributors submitted over 400 fixes, some stemming from issues identified by AI review tools. AI has not replaced the core maintenance workflow, but agents such as Sashiko have pushed bug-finding speed beyond humans’ capacity to triage and validate reports.

LongEarth-R1 Reasons Over Satellite Sequences of Up to 30 Frames, Outperforming Comparison Models Across All 12 Spatiotemporal Tasks

LongEarth-Bench organizes 117,000 remote-sensing images into approximately 120,000 long-sequence question-answer pairs, requiring models to track changes in landforms, anomalies, and missing states. LongEarth-R1, built on Qwen2.5-VL-7B, adds frame numbering, structured reasoning, and spatiotemporal rewards, but its data, weights, and code have not yet been released.

AutoDesign Lets Agents Rewrite Their Own Design Harness, Raising Average Poster Scores by 12.4 Points Across Seven Configurations

AutoDesign uses an outer agent to analyze execution traces and modify the production system, with an independent development set determining whether updates are accepted. The open-source DesignHarness outperformed several commercial systems on the authors’ PosterBench, but automated scores had a correlation coefficient of only 0.34 with human preferences.

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.

Intern-S2-Preview-397B Adds a Numerical Forecasting Branch, While a 4B Memory Module Raises the Average Biology Score by 3.40 Points

A new technical report brings scientific PDFs, time series, tool use, and long-horizon agent tasks into a unified training pipeline, while releasing the weights under Apache 2.0. The standalone Memory Decoder can add domain capabilities while keeping the 397B backbone frozen, but so far it has been demonstrated only with a biology module.
