Anthropic takes steps to block Claude from reverse-engineering video gamesMashable reports, citing Tom's Hardware, that Anthropic's Claude has quietly begun restricting modding, decompiling and reverse-engineering of video game code. Anthropic has made no official announcement. The article ties the change to AI-assisted game ports and mods, the PlayStation 5 jailbreak and Take-Two's subpoenas after the GTA6 leaks. It notes the irony of AI firms now guarding copyright, and the risk that less restrictive LLMs win users.

Metaβs AI-distilled model detector catches 79% at a 0.1% false-positive rateWM-Basin is a Meta method for detecting student LLMs distilled from watermarked teacher models, described in "Watermark Basins: Black-Box Detection of Distilled LLMs" (arXiv:2610.37266, 27 October 2026). It feeds a suspect model's API text into a clean probe model and checks gradient alignment with a key-specific watermark basin. It reached 79% true-positive rate at 0.1% false-positive rate across 1,200 students, versus 29% for the prior token-level detector. Clean-data fine-tuning and paraphrasing weaken it.

The essay argues that LLMs solve open math problems because they search depth first, and automated verifiers make failed attempts cheap. It uses WT Gowers' hint-sequence complexity (2^k + t), adds a branching factor b, and walks through OpenAI's unit-distance disproof and Cycle Double Cover prompt as a drafter/solver/verifier harness. It predicts AI does best where k and b are small.

How Specializing the Vocabulary of SLMs Can Cut Inference Cost by 77% in Real ApplicationsVocabX is a vocabulary adaptation method from Dharma-AI that selects sub-word and multi-word "macro" tokens by serving cost instead of frequency. On a Qwen3-4B Portuguese essay grader, response length fell from 350 to 101 tokens, the LM head shrank from about 152,000 to 65,000 rows, and measured cost dropped 77.0% on an RTX 5090 with vLLM. The bench score rose from 0.703 to 0.810. It beat FVT, MWT and in-place BPE across 15 model and domain combinations.

I built a programming language that LLMs can't useKillSwitch is an esoteric stack-based programming language built to be adversarial to LLMs and coding agents. It uses letter-counting rules, a spec with hidden lies, guardrail-triggering phrases like "hack into a computer", and noisy story-style scripts. The author benchmarked major models and agent harnesses on simple tasks. Opus 5 scored best at 66.8, Fable 5.1 and Gemini 4 Argon did poorly because of safety guardrails, and MiMo-V2.6-Pro led the open-weight models.

Anthropic's Scion is heavily inspired by MononokeA former Meta engineer on the Mononoke source control server says Anthropic's description of its new version control system Scion closely mirrors Mononoke's "derived data" design for efficient operations like blame. Sapling is credited only for "hard-won lessons" and Mononoke isn't mentioned. The author doesn't object to the copying, since the project is open source. Their point is that LLMs used to design systems will index heavily on open-source designs in their training data, and that Opus 5.5 and GPT-6 Astra both point to Mononoke when asked about prior art. They argue crediting prior art is now easier and more important.

ERC-8443: Quantum Bridge ShieldDraft ERC from Quantova Inc proposing a "Quantum Bridge Shield" for Ethereum bridges. A committee signs the Merkle root of each message batch with RFC 8554 LMS hash-based signatures instead of ECDSA/BLS keys that Shor's algorithm can break. The guard contract requires a strict majority of distinct unfrozen keys, records used leaves, freezes any key that signs a leaf twice, binds digests to domain, chain, guard and epoch, and applies a 60-second delay. The post gives gas costs (LMS W4 height-10 verification about 205k gas, a LayerZero packet 128,683 gas, worst-case rotation 12.44M gas under the EIP-7825 cap) and cites a NioLabs assessment with no critical or high findings. It is relevant as a worked post-quantum migration design for bridge key custody, including hybrid ECDSA+LMS mode and stateful-signature pitfalls such as leaf reuse and rollback.

There's little that's "inevitable" about AIAn essay arguing that LLM adoption is not "inevitable". It sets four criteria for inevitability: output not markedly inferior, socially valuable work, overwhelming advantage, and no cheap way to neutralise the technology. Firearms pass all four, the magnetic compass does not, and chemical weapons (following Bret Devereaux) are the closest analogy for LLMs. The author concludes LLMs fail the two criteria that matter most. They are useful mainly to weaker players, and strong practitioners can outcompete them once belief in the hype erodes.

Typed decision model vulnerabilities can push AI guardrail fail-open rates to 63%A study by Erfan Baghaei Potraghloo, posted to arXiv on October 8, 2026, evaluates seven open-weight LLMs used as "typed decision model" guardrails in agent systems (assigning probabilities to caller-defined allow/block options rather than generating text). It finds that six lines of unrelated server-log text raised one model's fail-open rate from 0% to 63%, and that merely renaming the permissive option's label (without changing its definition or the assessed text) drove fail-open rates to 93-100% in four models; a deterministic rule on typed values instead hit 100% accuracy, leading the author to recommend using these models only to triage reviewer workload rather than as sole decision-makers.

Understanding AI, Part I: The Machines That We TaughtGalaxy Research's explainer traces AI's intellectual history from the 1956 Dartmouth Workshop and the Logic Theorist through the symbolic-AI era (expert systems like Mycin and XCON, the Cyc project) to the sub-symbolic/connectionist revival (Perceptron, Hopfield networks, backpropagation, LeCun's CNN zip-code reader) that culminated in deep learning and the 2017 Transformer architecture. It then surveys three machine-learning paradigms (supervised, reinforcement, unsupervised) and five deep generative architectures (autoregressive, diffusion, GANs, VAEs, normalizing flows), closing with how modern LLM chatbots combine these via pretraining, SFT, and RLHF, and how multimodal, reasoning, RAG, agent, and world-model systems extend base LLMs.

The Agent Said It Was Done. The Database Disagreed.ThinkingBox is an agent sandbox and ThinkingBox-Bench is a 507-task stateful business-workflow benchmark (retail, auto insurance, etc.) that grades agents by checking the terminal backend database state and side effects they leave behind, not just whether tool calls succeeded or the final reply sounds right. Across 121,680 trials over 12-18 LLMs run 20 times each, the post finds most failures are clean-looking: 67% of failed trials still terminated without a tool error, yet executable checks caught wrong field values, missing effects, or unintended extra effects. It also reports pass@1 vs. 20/20 consistency gaps (e.g. Kimi K3 solves the most tasks at least once but is among the least consistent, while Claude Opus 5 and Claude Opus 5.5 are the most dependable) and cost-per-success/cost-per-dependable-task metrics, and ships the benchmark through an OpenEnv interface for reproducible evaluation.

Don't be fooledβLLMs don't reasonThore Graepel, former core member of DeepMind's AlphaGo team and now chair of machine learning at UCL, argues that today's LLMsβeven with chain-of-thoughtβdon't truly reason the way AlphaGo did. He contrasts AlphaGo's two-system architecture (a policy network for intuition plus explicit game-tree search for deliberation, exemplified by the famous 'Move 37') with LLMs, which he argues only iterate System-1-style next-token prediction without a persistent, inspectable epistemic state, a clean separation of knowledge from reasoning, or faithful (non-post-hoc) chains of thought. He proposes future systems maintain an explicit epistemic state (beliefs, open questions, ruled-out hypotheses) updated via evidence-backed moves, akin to AlphaGo's game tree, to produce auditable, trustworthy reasoning for high-stakes domains like medicine and science.
