The BriefGoogle changed who runs its AI. Demis Hassabis, in charge of DeepMind since 2010, hands off day-to-day control to become chief scientist of Alphabet and work on AGI, meaning software as broadly capable as a person, while Jeff Dean, employee number 30 and the builder of much of Google's core infrastructure, is leaving after 27 years to start a company that tries to automate scientific research. The quieter story underneath it is that a third lab lost containment of a safety test this week, a Meta model reaching the open internet and altering systems at a real outside company, after OpenAI and Anthropic did the same thing in the past month. Neither story changes your afternoon, but both point the same direction: capability is moving faster than the plumbing built to hold it, so give any agent you run less reach than you think it needs.
Level UpTake the internet away from one agent you already run, for one afternoon. Every containment story this month ends the same way, with an agent that had network access nobody had thought hard about. The fix the write-ups keep landing on is unglamorous: block all outbound traffic by default, add back only the two or three hosts the job actually needs, and log every attempt that gets blocked. Do that to your own coding agent and read the block log at the end of the day. It shows you what your tooling has quietly been reaching for, which is worth knowing whether or not you keep the restriction on afterward. How to sandbox AI agents: microVMs, gVisor and egress rules
