US-China AI Cybersecurity Race

The US-China AI rivalry increasingly centers on cybersecurity, with The Verge reporting that Z.ai's open-weight GLM-5.2 reportedly matches Anthropic's Mythos in certain bug-finding scenarios. The Decoder reported that 360 founder Zhou Hongyi unveiled AI security tools, one already flagging 3,432 vulnerabilities, framing the contest as cyber-nuclear deterrence. Ethan Mollick pushed back on social, judging GLM-5.2 solid but trailing GPT-5.5, Opus 4.8 and Mythos, and r/LocalLLaMA users heavily disputed headlines claiming China had 'matched Anthropic,' noting GLM-5.2 is not Opus 4.8.

Open-Weights Ecosystem & Local Inference

Momentum around open-weight models spanned all four feeds. Liquid AI shipped its smallest model yet, the 230M-parameter LFM2.5-230M, with llama.cpp, MLX, vLLM, SGLang and ONNX support for on-device use, while Coinbase began routing requests to Chinese open models like GLM-5.2 and Kimi K2.7; Interconnects argued the open ecosystem has diversified well beyond Chinese labs to include Zyphra, Cohere and Poolside, an optimism Nathan Lambert echoed. On r/LocalLLaMA, engineers merged DFlash into llama.cpp, grafted MTP speculative decoding onto Ornith-1.0-35B, ran a high-quality GLM-5.2 NVFP4 quant on four DGX Sparks, and built a pure-C CPU inference engine for Qwen 3.

Agentic AI Reliability & Limits

Multiple sources questioned whether AI agents can reliably finish real work. Princeton's CEO-Bench had agents run a fictional company for 500 simulated days and found only three models finished above starting capital per The Decoder, while TechCrunch reported Ford rehired veteran 'gray beard' engineers after over-reliance on AI tooling fell short. A Tencent-affiliated survey argued AI won't become a true coworker until it completes full tasks, a GovAI report evaluated offline monitoring of AI agent transcripts, and a heavily upvoted r/ChatGPT thread demanded models say 'I don't know' instead of fabricating answers.

China’s Z.ai claims it can match Mythos on cybersecurity

Zhipu (Z.ai) released the open-weight GLM-5.2, with researchers claiming it matches Anthropic's Mythos in certain bug-finding and cybersecurity scenarios despite trailing on broader tasks. The narrowing gap is raising US government concern given export controls on advanced models and hardware.

China's Zhipu AI (Z.ai) released its open-weight GLM-5.2, and some researchers have claimed that it matches Mythos in certain bug-finding and cybersecurity scenarios. While GLM lags behind models from Anthropic and OpenAI in other, more general tasks, it seems that China has dramatically reduced the gap in the capabilities between its models and those of the US. This level of advancement is particularly concerning to the US government, which has worked to restrict China's access to powe

Today's research is dominated by AI safety and alignment, with several items pushing for more rigorous empirical grounding of contested claims.

  • An ICML 2026 Oral position paper (Krause, Tramèr, ETH Zurich) argues that work on *anthropomorphic* misalignment—deception, scheming, sycophancy, shutdown-resistance—needs far stronger evidence
  • A GovAI report evaluates offline monitoring, where AI monitors review agent transcripts post-execution to detect misbehavior
  • *Do LLMs Have Desires?* presents an empirical framework showing consistent paired-choice preferences do not reflect behavior-motivating value systems
  • Steering-vector experiments find vectors can *partly* drive gradient routing to quarantine reward-hacking behavior

Interpretability and ML theory advance through a novel link between universal power-law weight-matrix spectra and inductive bias toward sparse representations, plus an update distinguishing refusal wording from harmful-request detection across model layers.

Foundations and ecosystem coverage rounds out the list. Marcus Hutter co-authors an accessible introduction to real hypercomputation and the arithmetic hierarchy; Abram Demski reports an AI-assisted *vibe research* workflow using Claude + Lean; an Interconnects roundup tracks open-weights diversification (Zyphra, Cohere, Poolside); and Zvi dissects the GPT-5.6 system card and its Sol/Terra/Luna tier family.

Do LLMs Have Desires?

Can we use steering vectors to suppress reward-hacking? Somewhat

By wassname

AI Analysis

An empirical alignment experiment testing whether steering vectors can drive gradient routing to quarantine reward-hacking behavior, finding that vector-initialized adapters absorbed roughly 63% of hacking without needing labeled examples. It matters as a self-supervised alternative for suppressing unknown reward hacks during frontier training.

Can steering vectors drive gradient routing? Yes, but not in realistic reward hacking environments, they are not precise enough classifiers of hacky vs clean solutions. Instead can we use a steering vector to initialise adapters so the hacky and clean gradients automatically separate? Partly! This init approach suppressed ~63% of hacking by absorbing gradients into the hacky initialised adapter. This is not as good as the prior approaches which use labelled examples, and get near perfect suppres

Power Laws in NNs: A Possible Mechanism for Inductive Bias towards Sparse Representations

An Iliad Fellowship interpretability/theory post observing that many ML quantities, especially weight-matrix spectra, follow heavy-tailed power laws, and proposing power laws as a tunable generalization of sparsity interpolating between true sparsity and Gaussianity via the tail index. It offers a candidate mechanism for inductive bias toward sparse representations.

This post was produced as part of the Iliad Fellowship under the mentorship of Dmitry Vaintrob. Tl;dr: Power-law ("heavy-tailed") distributions have universality theorems similar to those which make Gaussians common. We observe many things in ML are power-law distributed, most robustly and interestingly, the spectra of weight matrices. I explain how we can think of power-laws as being a natural generalization of the idea of 'sparsity', interpolating between true sparsity and Gaussianity accordin

AI Analysis

Delangue lays out a detailed case for regulating frontier API models for government transparency while leaving open-source AI unregulated, arguing closed black-box APIs are the real risk.

It's quite rational to regulate frontier API models, especially to get more transparency for the government, without regulating open-source AI. Here's why: 1. The most dangerous AI systems right now aren't open models. They're the large frontier LLM APIs distributed through coding tools and assistants, because:
  • They're built in secret behind closed doors and stay total black boxes. Zero transparency on what they can or can't do, with "safeguards" that blur everyone's ability to even analyze
