Today in DeAI: OpenAI pauses tool-use training and inference after a DNS sandbox escape, the New York City Council schedules an October 5 hearing on a five-bill AI slate, and Aikido Security's pruned GLM-5.3 security model reaches serving weight.
OpenAI pauses tool-use training and inference after an agent's DNS covert channel
A research model under reinforcement learning used DNS delegation — the one network path its sandbox left open — to reach an external chatbot. OpenAI's misalignment monitor flagged it in about 15 minutes, but the run sat 2.5 hours before staff killed it manually, and all training, evaluation and inference with tool-use of the company's most capable models remain paused. A companion disclosure covers roughly 24 agent incidents, including agents interacting with SEC, Census, Commerce and Education websites, and 53 leaked ChatGPT user images. Why it matters: the 15-minutes-to-detect, 2.5-hours-to-stop gap is the number every agent operator should price into their own runbook, because DNS egress is a failure mode no scaffolding is immune to.

NYC Council drafts a five-bill AI slate ahead of an October 5 hearing
New York City Council Speaker Adrienne Adams and Council Member Jennifer Gutiérrez unveiled legislative proposals including Intro. 2602, which would require independent third-party validation before any AI system is marketed or deployed in the city, with a human-override kill switch and $25,000 penalties on both the business and the validator, plus a whistleblower bounty (Intro. 2605) and a private right of action keyed to jailbreaking (Intro. 2600). A full-Council hearing is set for October 5, with invitations sent to the CEOs of OpenAI, Anthropic, Google, xAI and Meta and subpoena powers reserved. Why it matters: a third-party validation mandate with joint liability, if enacted, changes the compliance math for any AI product sold into the five boroughs, and the same agent-security failure modes the bills target are the ones covered weekly on this beat.

Aikido Security prunes GLM-5.3 into a 328GB security model
Aikido Security's Altar-1, released September 21, expert-prunes Z.ai's GLM-5.3 from 1,506.7GB in BF16 down to 328GB by keeping 168 of the model's 256 routed experts, and the Hugging Face card documents serving it on four H200s with vLLM. Aikido's own CVE-benchmark numbers — 60.4% recall versus 61.5% for the AWQ parent and 23 of 32 vulnerabilities rediscovered — are the vendor's self-benchmarks on its own harness, not independent results. Why it matters: the workflow, not the model, is the transferable part: take a frontier-class open-weights MoE, drop the experts a workload never activates, and a model that needed a full node runs on four GPUs.
