Nvidia Groq Chip for OpenAI Inference
Nvidia is preparing a custom processor for OpenAI and others, integrating Groq's chip tech for faster AI inference. This business shift could redefine AI competition. Unveil at GTC conference next month in San Jose.
US Gov Flags Grok Risks, Pentagon Clears It
Multiple US federal agencies have raised concerns about xAI's Grok chatbot's safety and reliability. A GSA report states Grok-4 fails federal AI safety standards, yet the Pentagon has approved it for classified operations. Agencies apply varying risk tolerances based on missions.
US Gov Warns on xAI Grok Safety
US federal agencies have voiced concerns over xAI's Grok chatbot's safety and reliability in recent months. Officials highlighted ongoing government divisions on AI model deployments. The warnings stem from informed sources.
Global Carmakers Profits Halved in 2025
Major automakers like VW, Mercedes, Ford, GM saw profits drop 50%+ due to EV transition pains, tariffs, China competition. Tesla reports first revenue decline, halting models to focus on commercial and AI. Strategic resets underway across industry.
US Gov Blacklists Anthropic Partners
US Department of Defense reportedly prohibits contractors and partners from commercial dealings with Anthropic. This could sever Anthropic's cloud ties like AWS, pushing users toward local models. Speculation links it to OpenAI-US gov alliance against Anthropic.
LLM Decodes Sspai 2025 Top Content
Sspai's annual essay uses LLMs to analyze 2025 popular articles. High-engagement pieces prioritize authenticity over polish. Reveals LLM perspectives on quality content.
Qwen3.5 Transforms Local Coding Workflows
User reports Qwen 3.5 enables hands-off agentic coding loops on modest hardware, outperforming prior local models. Achieves 4-6 hours of unsupervised work despite benchmarks not indicating major leaps. Marks a personal tipping point for local LLM productivity.
VeRO: Harness for Agent Optimization
VeRO introduces a reproducible evaluation harness for agent optimization, featuring versioned agent snapshots, budget-controlled evaluations, and structured execution traces. It provides a benchmark suite of target agents and tasks with reference procedures. An empirical study compares optimizer configurations, revealing effective modifications for improving agent performance, and releases VeRO for community research.
SSR Boosts Math Reasoning via Strategy Gaps
Example-based guidance for math reasoning is unstable due to gaps between strategy usage and executability, differing systematically between humans and models. The paper proposes Selective Strategy Retrieval (SSR), a test-time framework that selectively retrieves and combines source-aware strategies using multi-route signals. SSR delivers consistent gains, up to +13 points on AIME25 and +5 on Apex for compact models.
SideQuest: Model-Driven KV Cache for Agents
SideQuest uses the Large Reasoning Model (LRM) itself to compress KV cache by reasoning about token usefulness in long-context agentic tasks. It runs compression as a parallel auxiliary task to avoid polluting the main reasoning context. Evaluations with a model trained on 215 samples show 65% peak token reduction with minimal accuracy loss, beating heuristics.
MBT Distills Metacognition into LLMs
Large Reasoning Models fail complex tasks due to poor self-regulation despite valid steps. Metacognitive Behavioral Tuning (MBT) injects metacognitive strategies via MBT-S (synthesizing traces) and MBT-R (rewriting traces). It boosts accuracy on multi-hop QA benchmarks with fewer tokens.
Math Theory Distinguishes AI Agency from Intelligence
Researchers define bipredictability (P), a measure of shared information between observations, actions, and outcomes, proving strict bounds: up to 1 in quantum, ≤0.5 in classical systems, lower with agency. Validated on double pendulums, RL agents, and LLM conversations, it separates agency (acting on predictions) from intelligence (learning, self-monitoring, adapting). Current AI achieves agency but lacks intelligence; a new feedback architecture monitors P for resilient systems.
LLMs Map AI Trends in LCA
This arXiv paper reviews AI integration in life cycle assessment (LCA) using large language models (LLMs) to uncover trends and themes. It highlights dramatic growth in AI adoption, especially LLMs, and correlations with LCA stages. The study introduces an LLM-based text-mining framework for scalable literature reviews.
Fixing Rater Bias in AI Evals with IRT
This paper integrates psychometric rater models into AI evaluations to correct systematic errors from human raters. It employs Item Response Theory, particularly the multi-faceted Rasch model, to disentangle true output quality from rater effects like severity and centrality. Applied to OpenAI's summarization dataset, it delivers adjusted quality scores and rater diagnostics for more reliable AI assessments.
CourtGuard: Zero-Shot LLM Safety Framework
CourtGuard is a retrieval-augmented multi-agent framework that treats LLM safety as an evidentiary debate using external policy documents. It achieves state-of-the-art results on 7 safety benchmarks without fine-tuning, outperforming policy-following baselines. It excels in zero-shot adaptability (90% accuracy on Wikipedia Vandalism) and automated curation of 9 adversarial datasets.
ConstraintBench: LLM Optimization Benchmark
ConstraintBench introduces a benchmark for LLMs to solve constrained optimization problems directly without solvers across 10 operations research domains. Evaluations of six frontier models on 200 tasks show feasibility as the key bottleneck, with the best achieving 65% constraint satisfaction but low joint optimality. The benchmark and evaluation tools will be publicly released.
Cognitive Models Template LLM Agent Design
This arXiv position paper argues cognitive models and AI algorithms offer blueprints for modular language agents combining multiple LLMs. It formalizes 'agent templates' defining LLM roles and compositions. Surveys existing agents to highlight their cognitive/AI inspirations for interpretable designs.
AHCE Boosts LLM Agents with Human Expertise
AHCE framework augments LLM agents in specialized domains by requesting structured expert reasoning via a learned Human Feedback Module (HFM). Experiments in Minecraft show 32% success rate gains on normal tasks and nearly 70% on hard tasks with minimal human input. It advances beyond basic help requests to treat humans as interactive tools.
Agentic AI Optimizes Cell-free O-RAN
This arXiv paper proposes an agentic AI framework using LLM-based agents for intent-driven optimization in cell-free O-RAN. A supervisor translates intents into objectives and rate requirements, while specialized agents handle weighting, O-RU management via DRL, and monitoring. PEFT enables LLM sharing, reducing active O-RUs by 41.93% and memory by 92%.
