AI4AI-Bench evaluates hyperparameter tuning separately from genuine changes to learning methods, requiring coding agents to submit training code that can be rerun from scratch. Across 290 trials involving six systems, more than 40% underperformed the original algorithms, while increased reasoning effort mainly made agents more willing to modify core training mechanisms.

DSX MaxLPS uses real-time telemetry to reallocate unused power. NVIDIA found that the provisioned power for a GB200 NVL72 rack could be reduced from 125 kW to 90 kW while maintaining throughput. The solution also combines workload-specific power profiles with 45°C liquid cooling, but its core Dynamic Power Software remains in Developer Preview.

Brain Researcher constrains neuroimaging analysis agents with a knowledge graph, typed workflows, and review rules, while preserving hypotheses, evidence, and execution provenance. Tool routing improved substantially, but the rate of successfully grounding claims in verifiable evidence remained just 22.0%, and automated review also failed to catch a directional statistical error.

SafeBranch rolls back an agent’s hazardous trajectory to a critical decision point and compares safe and unsafe actions only within the same context. The trained model requires no external critic at deployment, but results are currently limited to simulated household environments, and data construction still relies on GPT-4o judgments.
最新模型
ConceptGuard no longer treats the forget and retain sets as unrelated facts. Instead, it requires models to suppress harmful uses of a technology while preserving legitimate ones. All four unlearning methods exhibit a trade-off between forgetting and utility, with highly inconsistent results across concepts.

FormalTCS extracts research-grade problems from top theoretical computer science papers published over the past two years, measuring models stage by stage as they turn natural-language claims into machine-verifiable proofs. The best model achieves a Pass@8 of 28.6 when proving already-formalized theorems, but translating natural language into correct Lean theorem statements remains the primary bottleneck.

The open-source agent runtime Forge can now isolate MCP connections and credentials by user while automatically performing OAuth 2.1 metadata discovery and dynamic client registration. The release also adds granular egress controls and approval auditing, although MCP support currently remains focused on HTTP transport.

The new release raises the minimum Python version to 3.10 and removes Text Completions, several sampling parameters, and the client-side compaction interface. Most standard API calls require no changes, but monitoring, testing, and custom transport layers that depend directly on httpx must be migrated.

Daedalus-150M is designed specifically for single-user, 4-bit CPU inference, allowing most network layers to avoid repeatedly reading an ever-growing KV cache. Preliminary results indicate that its speed advantage increases with context length, but the model is limited to 2K context, and its performance figures still await independent reproduction across different hardware.
AI 安全
The new benchmark deduplicates agent skills from 13 public sources and splits them by structural family, preventing near-duplicate samples from appearing in both the training and test sets. The best text classifier performed strongly on a random split, but misclassified 62.4% of benign skills as malicious when evaluated on unseen sources.

NVIDIA has updated its open-source agent execution stack, focusing on state drift across vLLM, llama.cpp, Ollama, and the model router. The new release also tightens sandbox lifecycle management, image provenance, and failure recovery, though it remains a patch release in a rapidly evolving project.

New research shows that even when models refuse to disclose secrets directly, statistical features such as response length, formatting, and word choice may still carry contextual information. An adaptive black-box attack can recover nearly all two-digit secrets, while achieving an 82% exact-match rate for four-digit secrets.
