Microsoft’s Mage-VL replaces uniform video frame sampling with I/P frames, motion vectors, and residual energy, encoding only regions with significant changes. Its 4B model reportedly reduces visual tokens by more than 75% while preserving performance on static tasks, although speed and quality comparisons still come primarily from official tests.

Rather than feeding vector retrieval results directly to a language model, MemChain first plans, ranks, and compresses them into source-grounded active memory. The research reports state-of-the-art results on LoCoMo and LongMemEval-S, but full code and real-world latency costs have not yet been disclosed.

HiFi-UMI combines offline stereo-inertial SLAM, microsecond-level synchronization, and six-view bimanual capture in a portable data system, enabling human-only manipulation data to be used directly for robot post-training. Real-world success rates across three VLA/world-action models approached an in-situ teleoperation baseline, though the results remain limited to controlled tasks evaluated by a single team.

CAPA embeds implementation preferences that users repeatedly omit into 600 executable coding tasks, testing whether assistants can infer new requirements from past conversations. Across 12 models, adding same-user history increased final success rates by only 6.8 points on average, but raised first-try success by 15.6 points—suggesting that memory mainly reduces clarification rounds rather than eliminating failures.

Instead of using an LLM to judge travel plans, TREK verifies entities, budgets, opening hours, transportation, and implicit requirements individually. Even the best of 15 agents fully passed only 46.2% of solvable tasks, showing that locally correct answers remain difficult to assemble into executable itineraries.

SecRespond has security agents analyze read-only disk snapshots of compromised hosts instead of merely solving attack challenges in clean environments. Although 23 models could restate alerts, they commonly missed implants not disclosed by the alerts and failed to verify remediation.
新研究發現，on-policy 擴散蒸餾若只匹配 classifier-free guidance 合成結果，正、負分支的誤差可能互相抵銷。Positive-Direction Matching 將兩者拆開監督，在密集到稀疏的影片控制實驗中降低模型對推論 guidance scale 的敏感度。
AI 安全
MemTX no longer allows information written by agents to become immediately actionable facts. Instead, it adds evidence, authorization, provenance, snapshot isolation, and validated commits. The study reports zero downstream harm across five models, but the results still come from controlled evaluations and do not yet show that it can repair irreversible side effects in real-world external systems.

Baidu’s research team has released 100 long-horizon document, spreadsheet, and presentation tasks, along with human labor time, price proxies, and executable validators. The best model achieved an average score of 17.91, compared with the human baseline of 27.79, showing that cheap and fast inference does not necessarily produce deliverables that are ready to use.

BAAI reframes deep research as a recursive loop of “search—verify each constraint—conduct targeted follow-up searches,” while training the model to compress confirmed evidence and unresolved constraints on its own. The weights for a 4B dense model and a 122B-A10B MoE model have been released, but their advantages mainly come from automatically verifiable synthetic tasks and cannot yet be directly generalized to open-ended scientific research.

NVIDIA integrated Nemotron 3 Ultra into a “generate-test-reflect” RTL agent loop, achieving a 97.1% average pass rate across nine agentic task categories in CVDP. The results show that executable verification can significantly strengthen chip-design models, although data overlap, tool configurations, and vendor-run evaluations still limit generalizability.

Moonshot AI has officially released the Kimi K3 weights and technical report. The model features native vision, a one-million-token context window, and activates 16 of 896 experts for each token. The open weights finally make the company’s capability claims reproducible, but more than 1 TB of low-precision weights still put full deployment beyond ordinary workstations.
