Perplexity Moves Its Full Agent Stack to DGX Spark, Sending Only Difficult Steps to the Cloud with User Approval

Portable Computer runs a 27B model, planner, tool routing, persistent task queue, and search index locally, while permission prompts control data transfers. The initial release supports only Linux and DGX Spark, and its official results come from an unpublished internal workload that should not be treated as independent validation.

llama.cpp 0.3.0 Adds a Hybrid-Attention KV Cache, MTP, and Tensor Splitting for DeepSeek 4

llama.cpp 0.3.0 adds native support for dots3-note’s hybrid DSA/sliding-window attention and integrates multi-token prediction for GLM-4.5-Air. DeepSeek 4 can now use tensor splitting across multiple GPUs, but the release notes provide no comparisons of throughput, latency, or VRAM usage.

DeepRepoQA Uses Monte Carlo Tree Search to Trace Cross-File Code Relationships, but Evaluation Still Relies on LLM Judges

Rather than having coding agents search along a single path, DeepRepoQA uses MCTS to compare multiple repository exploration branches and synthesizes answers from evidence with line-number citations. Its authors report gains of 4 to 7 percentage points on SWE-QA, but data contamination, inference costs, and limited cross-language testing remain to be validated.

Sentence Transformers Releases a Domain Fine-Tuning Recipe for Multi-Vector Models, but Indexing Costs Remain Far Higher Than for Dense Vectors

Sentence Transformers has added a complete training workflow for `MultiVectorEncoder`, allowing ColBERT-style models to be adapted to specific domains directly with paired data. Medical retrieval experiments show that pre-supervised checkpoints adapt more readily to new domains, but the findings are based on only one dataset and a limited set of model families.

Root Access Can Abuse the Pixel Camera’s Hardware Key to Sign Fake Images, and C2PA Verification Will Still Pass

Security researcher David Buchanan used Keystork to impersonate the camera app and ask Android StrongBox to generate valid Content Credentials for arbitrary AI-generated images. The attack does not require exporting the private key; it exposes how a compromised signing endpoint can abuse a genuine key, rather than a flaw in C2PA’s signature algorithms.

NVIDIA Dynamo Prewarms a Standby Engine with Shared HBM Weights, Cutting Failover from 283 Seconds to 7.3 Seconds

Dynamo’s experimental Shadow Engine Failover lets two inference processes map the same GPU weights, avoiding a model reload after a process crashes. NVIDIA’s GLM-5.2 test showed a nearly 39× reduction in recovery time, but the feature currently primarily supports vLLM and cannot handle GPU, node, or cross-node failures.

Tencent Open-Sources WeMM-Embedding: 2B Model Outperforms Some 8B Baselines in Multimodal Retrieval Benchmarks

WeMM-Embedding processes text, images, video, visual documents, and interleaved inputs in a shared vector space and is available in 2B, 4B, and 9B sizes. Official results show it outperforming several public baselines, but the model does not support audio, and some product-level results are backed only by Tencent’s internal A/B tests.

LAION-BVD Releases a 10-Million-Hour Video Corpus, but Media Files Are Limited to Approved Noncommercial Research

LAION-BVD compiled 1.3 billion video URLs from Common Crawl and downloaded approximately 80 million videos totaling 10 million hours. The data pipeline and URL lists are public, but access to the main media subset is restricted, and researchers remain responsible for compliance.

JFrog Routes Coding Agent Package Installs Through Artifactory, but Routing Is Disabled by Default in the Preview

Agent Package Resolution uses session prompts, package manager configuration, and server-side policies to direct dependency downloads triggered by Claude Code and Cursor to Artifactory. The feature remains in preview, with no repository bindings in its initial configuration, and the plugin alone cannot prevent agents from bypassing it to access public registries.

Recuris Freezes Agent Weights and Recursively Rewrites Skill Memory, Improving Results in 35 Long-Horizon Task Evaluations

Recuris separates task state, skill selection, and failure evidence into memory components that can be updated independently, then validates each modification against held-out data. The authors recorded improvements in 35 of 37 completed model–benchmark pairings, although some gains were not statistically significant and the evaluations also relied on LLM-simulated users and judges.

Docling 2.122 Brings Compact Table Output to the Conversion API and Restores Legacy iWork Document Structure

Docling 2.122.0 allows batch conversions to directly output Markdown tables without column-padding whitespace and begins restoring headings, hierarchy, and tables from iWork ’09 files. The release also fixes OCR, PDF hyphenation, and layout-overlap issues, although the project has not quantified changes in performance or extraction accuracy.

EchoWM Integrates Six-Degree-of-Freedom Navigation and Native Audio Into a World Model, but the Interactive Code Has Yet to Be Released

The JD.com Joy Future Academy team has introduced EchoWM, which uses a unified trajectory interface to control 720p audiovisual worlds from both first- and third-person perspectives. The paper describes the system as an “open” model, but the currently linked repository still provides only a long-video pipeline; EchoWM’s code and weights have yet to be released.
