CAPA Tests Cross-Session Memory in Coding Assistants: Same-User History Raises First-Try Success by 15.6 Points on Average

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.

TREK Validates Travel Agents With Executable Rules; the Best Model Achieves Just a 46.2% Task-Perfect Rate

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 Reconstructs Post-Intrusion Forensics, With None of 23 Models Fully Detecting and Remediating a Single Testbed

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.

CAM-DF Reframes Agent Tool Ranking as a Cost-Aware Stopping Decision, Reducing Tool Exposure by 37%

New research argues that relevance ranking can determine tool order but cannot answer how many tools an agent should load. CAM-DF directly learns the marginal utility of continuing to load tools, reducing tool exposure by 37% while maintaining a comparable task success rate.

擴散蒸餾只對齊最終 CFG 速度可能掩蓋分支錯誤，PDM 改為分別約束正向預測與條件方向

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。

MemTX Turns Shared Agent Memory into Transactional Commits; Exhaustive Search of 5.5 Million Protocol States Finds No Safety-Rule Violations

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.

OmegaUse-OfficeVal Adds Per-Task Cost Labels for Office Agents, but the Best Model Still Trails Humans by More Than One-Third in Quality

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.

AREX Enables Research Agents to Repeatedly Verify Unresolved Constraints, While a 4B Model Uses Compressed State for Long-Horizon Search

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.

ACE-RTL Has Nemotron Iteratively Compile and Fix Verilog, Achieving a 97.1% Average Pass Rate Across Nine Task Categories

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.

Kimi K3 Releases 2.8T MoE Weights, With 104B Active Parameters Raising the Self-Hosting Bar to Cluster Scale

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.

Poolside Releases Laguna S 2.1: 118B MoE Activates Just 8.5B Parameters per Token

Laguna S 2.1 uses sliding-window attention, attention gating, and an FP8 KV cache to reduce long-context costs, targeting self-hosted agentic coding. The model comes with weights at multiple precision levels and complete evaluation trajectories, but its million-token capability, performance comparisons, and single-machine feasibility still depend heavily on the quantization format and runtime environment.

Same Model Doubles as Tool-Call Predictor, Boosting Qwen 4B Next-Step Hit Rate by More Than 17 Points

Researchers enabled agents to predict and pre-execute their own next tool calls during inference, replacing an external draft model with shared weights and a shared KV cache. Joint reinforcement learning raised average Hit@1 to 61.2 and 66.3 for two Qwen 4B models, respectively, though the paper has yet to quantify end-to-end speedups in real-world parallel deployments.
