"LLM-powered AI agents require high-frequency state exploration (e.g., test-time tree search and reinforcement learning), relying on rapid checkpoint and rollback (C/R) of the complete sandbox state, including files and process state (e.g., memory, contexts, etc.). Existing mechanisms duplicate the e..."

### Abstract

quantization-aware training (QAT) on the Huawei Ascend NPU platform. To address
two practical gaps for extreme low-bit LLMs—whethe..."
"The attack doesn’t come from your users.
It comes from your agent’s environment, the emails it reads, the webpages it visits, the documents it retrieves, the database rows it queries.
Every piece of external content your agent processes is a potential instruction source. And your agent has no way ..."

"Crescendo (Russinovich et al., USENIX Security 2025) is a multi-turn jailbreak designed specifically to evade output-based monitors. Each individual turn looks completely innocent. The attack only exists across turns.

It scores each prompt independently. It ha..."

"Background. Traditional safety benchmarks for language models evaluate generated text: whether a model outputs toxic language, reproduces bias, or follows harmful instructions. When models are deployed as agents, the safety-relevant object shifts from what the system says to what it does within an e..."

"Large language models (LLMs) exhibit systematic political bias across a variety of sensitive contexts. We find that LLMs handle counterpart topics from opposing political sides asymmetrically. We refer to this phenomenon as covert political bias and identify 7 categories of techniques through which..."
+++ One developer's PDF stress test reveals that "just upload it" vision models and boring old OCR have tradeoffs worth understanding, which is either obvious or news depending on your stack. +++
"I benchmarked vision-capable LLMs (the "just attach the PDF and let the model read it" pattern) against OCR-based pipelines on 30 long, image-heavy PDFs from MMLongBench-Doc (https://github.com/mayubo2333/MMLongBench-Doc). There were 171 questions in ..."

"Autonomous agentic systems are largely static after deployment: they do not learn from user interactions, and recurring failures persist until the next human-driven update ships a fix. Self-evolving agents have emerged in response, but all confine evolution to text-mutable artifacts -- skill files,..."
"After a few months running long projects with AI agents (some spanning weeks, with multiple specialist agents touching the same files), I kept hitting the same failure mode. The specialists were fine at their narrow task. What broke down was project memory. Decisions made in week 1 were lost by week..."
"Anthropic’s 31 small-business skills reportedly hit around 382,000 downloads on day one.
And now someone has mapped the whole thing into a setup workflow that can apparently be deployed in \~10 minutes.
This is actually a pretty interesting shift.

While most existing systems communicate through natural language, recent work shows that latent communication, particularly through transformer key-value (KV) caches, can..."
"Most road-damage models report frame-level mAP. Road authorities don’t buy mAP - they buy “which 100 m of asphalt is bad, how bad, where,” in a format their pavement-management system can ingest.

We ask whether the polarity of prior conversation history biases subsequent judgments, an effect we call the accumulated messa..."
