NVIDIA and HPE used HPE Discover to re-pitch the \"AI factory\" for the era of agents, Google Cloud detailed how Siemens is \"slicing the elephant\" to modernize legacy industrial code with agentic workflows, and InfoQ went deep on the unglamorous distributed-systems work of keeping cloud browser infra alive under bursty, stateful agent traffic. The theme underneath all three: agentic AI is moving from demo to load-bearing, and the hard part is the plumbing.","That maturation showed up just as loudly on the safety-net side. A cluster of Show HN launches — Kintsugi (a local-first guardrail that intercepts an agent's real shell commands before rm -rf or DROP TABLE lands), PromptShark (a MitM proxy and loop detector for agents), and the Deep-XPIA prompt-injection benchmark — all point at the same anxiety: agents now run real commands on real machines, and the tooling to contain them is racing to catch up. Stack Overflow even announced an API-first knowledge exchange aimed at agents rather than humans.","On the policy front, Simon Willison kept pulling at the thread of the Fable 5 \"jailbreak\" report, quoting Katie Moussouris and The Atlantic on how export controls around frontier-model cyber capabilities may be hurting US cyber defense more than helping. And in the quieter corners, hardware and local models reminded everyone the substrate keeps improving: Blackwell swept MLPerf Training 6.0, and Qwen3.6-27B is now good enough to be someone's daily local coding model."],"highlights":["NVIDIA + HPE expand the \"AI factory\" for agents at HPE Discover; Siemens shows Google Cloud agentic workflows modernizing legacy industrial code.","A wave of
