A Kyoto University team created MemUse from a four-month real-world deployment, separately evaluating whether a model can retrieve a memory and whether it uses that memory in an appropriate response. The results show that expanding memory capacity substantially improves direct QA, but does not produce corresponding gains in natural integration or overall user satisfaction.
AI 安全
A team including the Shanghai AI Laboratory has released StepGuard, a 4B-parameter model that uses paired safe/dangerous trajectories and Balance-GRPO to calibrate overblocking and missed detections. It substantially reduces attack success rates in two agent environments, but its training corpus and data generator have not yet been released, and it still misses some policy violations.
推論系統
SemiAnalysis has released AgentX, featuring long-context, multi-turn, and concurrent subagent workloads so inference systems are no longer compared solely using fixed-length prompts. The dataset preserves request timing and KV-cache reuse patterns, but its sources are concentrated on Claude Code, and it measures serving-system efficiency rather than programming-task correctness.

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 The initial release supports only Linux and DGX Spark, and its official results come from an unpublished internal workload that should not be treated as independent validation.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 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.
最新模型
Alibaba has released the Qwen3.8-Flash-Next weights. The model uses Gated DeltaNet to compress most historical state, while Qwen Sparse Attention retrieves information from the full context. It natively supports 262K tokens, but the official million-token performance and agentic evaluations have yet to be independently reproduced.
檢索與 RAG 工具
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.
AI 安全
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.
最新模型
Thomson-1.0-Small extends Qwen3.6-35B-A3B through mid-training on proprietary documents, synthetic rewrites, and general-capability replay data. Official evaluations show improved legal-agent capabilities, though the model trails the base model on some general and coding tasks.
IBM 的兩款英語語音辨識模型把輸出速率降至每秒12.5個token，並以三段時間下採樣減少運算。官方在單張H200測得每秒處理逾3.5小時音訊，但這是大批次吞吐量，不等同互動串流延遲。
Multiverse Computing 改由原始 120B 模型直接蒸餾經結構壓縮及量化的 60B 學生模型，避免把中間恢復模型的誤差當成學習上限。結果顯示 4-bit 模型可超越同架構 BF16 檢查點，但未全面追回原始教師的能力。

Anthropic is giving chat and its task-execution interface, Cowork, a shared set of editable memories and will now update them during conversations. Sensitive topics are excluded by default, but memory is enabled by default on general consumer plans, and users cannot prevent only one interface from accessing it.
