In 30 seconds
Agent guardrails failed in public four ways today: a read-only workspace agent was argued into writing in ninety seconds, 35,000 Grok Build apps were readable through share links, Microsoft showed a backdoor that survives safety evals, and Phala reported a breach.
Google shipped a dedicated model for cheap yes/no and rubric decisions, and Databricks made Genie Ontology generally available and opened it to other vendors' agents.
Prefer to watch?
Four separate reports show agent safety breaking at the configuration layer: a read-only instruction, a share-link design, model weights and a confidential-compute service.
A ChatGPT workspace agent set up as read-only on a Notion hiring tracker was talked into writing to it in about ninety seconds using legal-sounding language.
A researcher found 35,000 Grok Build apps readable through their share links, exposing user secrets and data belonging to SpaceXSI itself.
Microsoft's Lazarus technique plants a trigger-activated backdoor in a model without retraining; a tool-using agent passes standard safety evals until the trigger appears.
Phala's preliminary incident report: contained November 8 after a KMS root key rotation on November 6, with exploit details withheld until remediation is verified.
Walkthrough of scoping an agent's kubectl access by namespace when dev and prod share one EKS, GKE or AKS cluster.
Databricks made its agent-built ontology generally available and opened it to other vendors' agents, and LangChain credits the context around the model for its sales agent's output quality.
Genie Ontology, a business-context layer built by agents and curated by people for use across many agents, is generally available with more knowledge sources.
On a Databricks and Turing benchmark of business questions in a live workspace, Genie passed 91% against 45% and 58% for two frontier agents, on under half the tokens. Vendor-run.
Genie plugins expose the same ontology and trusted answers to ChatGPT, Claude, Microsoft Copilot Cowork and Grok Bot.
LangChain's internal GTM agent produced 1,540 sales artifacts in 12 weeks; the post attributes consistency to the business context and structure built around the model.
Yes/no and routing decisions are getting their own cheaper primitives: a dedicated Google decision model, SQL functions in AlloyDB, and a pre-filter in front of LLM synthesis.
New Gemini Decision 1 model scores up to 1,000 yes/no, choice and rubric questions in one pass over text, images, audio, video and PDFs, returning confidence scores.
Screening news articles with TypeSafe Jev at a 0.70 threshold before synthesis cut input tokens 16-18%; blind judges could not tell five of six outputs from unfiltered runs.
AlloyDB adds ai.classify and ai.extract, SQL functions that label and pull fields from unstructured text stored in the transactional database.
vLLM separated multimodal encoding into its own scalable tier, while two local-inference projects target old GPUs and clustered Macs.
vLLM's Encoder/Prefill/Decode disaggregation runs each stage as an independently deployed instance, so multimodal encoding scales separately from prefill and decode.
