llm 0.37

LLM 0.37 is a release of Simon Willison's LLM CLI tool and Python library, covering about two months of changes. It adds gpt-6.1-sol and gpt-6.1-terra, a new `llm openai endpoint add` command for OpenAI-compatible endpoints, and a cheaper default model, gpt-6-luna. Embeddings now accept differing content types, as Gemini Embedding 2 needs. Willison says AI-assisted PRs from 12 authors were easy to review.

Training activation classifiers for safety and alignment

Training activation classifiers for safety and alignment describes how OpenAI trains lightweight probes on a model's residual stream activations to flag misaligned or policy-violating completions. Probes use an MLP plus QV-attention architecture with an exponential moving average and a rolling softmax objective. They run in streaming mode on the inference engine, have run on all assistant completions since GPT-5.6, and transfer well across post-training checkpoints but less across pre-training checkpoints.

Scaling Git at OpenAI

Pando is OpenAI's new Git backend, built to handle the push and fetch load Codex puts on its monorepo. It stores pushed packfiles in blob storage, tracks per-branch ref versions with causal consistency, and reuses packs across fetches. OpenAI reports nearly 5x lower median push latency and about a petabyte of Git data served per day. It was built in 10 weeks with Codex agents.

BTCPay Server warns of hot wallet thefts targeting outdated instances

BTCPay Server, an open-source self-hosted cryptocurrency payment processor, reports attackers draining hot wallets on instances running version 2.4.1 (July 23, 2026) or earlier. Attackers logged in as administrators on versions older than 2.4.2. Users should update to 2.4.7; the exploited flaw is not disclosed. An October 29 critical vulnerability found by Anthropic's Frontier OSS scanner prompted 2.4.7. The August 7 release 2.4.2 had already warned of an exploited LND credential exposure.

Malicious Claude Code Extension Served in Cursor Supply Chain Attack

Malicious versions 2.1.312 and 2.1.313 of the anthropic.claude-code extension were live in the Cursor VS Code Extension Marketplace for about 11 hours on October 29. The JavaScript ran at module load, collected host details, tried to install an SSH key, open a reverse SSH tunnel and set persistence on macOS and Windows. Kevin Beaumont estimates about 5,000 downloads. Cursor rotated keys, rebuilt the marketplace and published a detection script and IoCs; uninstalling alone does not remove the dropped persistence scripts.

Polymarket Returns $3.9 Million to Traders as DebugBear Cites DNS Hijack

Polymarket is returning $3.9 million to traders after an October 29, 2026 supply chain attack in which malicious JavaScript was served from a DebugBear address its site loaded. DebugBear says its DNS records were compromised through its domain registrar, and attackers appear to have targeted one customer. The script abused open trading sessions to sell positions or move assets; 726 wallets were affected, and about 5,500 wallets received $1.19 million for halt and forced-sale losses.

So I guess everyone uses LLMs to think now

The eva.ac author argues that recent AI-credited vulnerability findings come from skilled researchers steering LLMs, and that AI firms use disclosures as marketing. Cases cited: Calif, OpenAI and Wiz framing PHP2Shell differently; a hash teaser before the Tailscale "tailworm" privilege escalation (author's account: Tailscale not contacted); and the eMudhra CA key found without AI. No sources, dates or CVEs are given.

"So I guess everyone uses LLMs to think now" is an opinion post from the eva.ac blog. The author explains why they never use LLMs for published research: they do it for fun and cannot take credit for model output. They argue LLMs still need skilled guidance, criticise AI-company security marketing (PHP2Shell from Calif, OpenAI and Wiz), and cite the Tailscale "tailworm" disclosure and the eMudhra key found without AI.

How to Run an AI Model Locally—And Why You Might Want To

Decrypt guide to running open-weight AI models locally with Ollama and LM Studio. It cites Epoch AI's finding that open models trail the best closed ones by about four months, and sets out VRAM and unified-memory needs (8GB minimum, 24GB for serious use), quantization, licences (MIT, Apache 2.0), install commands and Gemma 4 download sizes. It also notes that the largest open models, such as Qwen3.8-Max, exceed consumer hardware.

How We Took Over ChatGPT Accounts

Simon Willison summarises Parameter Labs' ChatGPT account takeover chain against the HTML previews (formerly Canvas) sandboxed iframe.

Weekly Research Brief: Binance Hacked; Hyperliquid on Wall Street; Prediction Markets’ Brazil ‘Miss’

Galaxy Research's weekly brief of 30 October 2026 opens with the Binance hack: about $6.3b drained across 10 blockchains, attributed by TRM Labs and Chainalysis to TraderTraitor (Lazarus-linked). The attacker used EIP-7702 with 50 pre-signed authorizations on Ethereum, and Binance's preliminary finding is a compromised DevOps laptop reaching a service container. Tether and Circle froze about $2.6b. The other sections cover Hyperliquid and prediction markets.

Was I wrong about open models & cyber risks?

Interconnects post in which Nathan Lambert revisits his claim that an open-weight Claude Mythos would have been survivable. He argues GLM-5.3 already crosses the capability threshold with little visible societal change, and quotes Rob Wiblin, Anthropic and Zvi Mowshowitz as examples of exaggerated warnings. He cites Epoch AI's Firefox exploit built with GLM-5.3, and treats the recent vulnerability surge as an ecosystem trend driven by AI capability and diffusion, not open versus closed models.
