★ Must-ReadOpenAI hit the brakes on its next model after it got close to 'critical' hacking skillOn August 18 OpenAI said it paused its largest training run for two weeks. Early testing suggested the upcoming Astra model might find and use unknown security holes on its own, a level OpenAI itself labels Critical cybersecurity capability. This is the clearest case yet of a lab slowing itself down because of what its own model might do, not because a regulator made it. Read it two ways at once: real caution, and a company telling you how powerful its next product is.
📚 LearnGoogle put a Gemini assistant inside the Workspace admin consoleAdmin Assist rolled out August 17. Admins can ask in plain English how to change a setting, find a user, or read a report, and it answers from Google's own admin docs with links into the right console page. If you manage Google Workspace for clients, this is a real time saver on the long tail of settings nobody remembers the path to. It also means your clients' office managers can now find those settings themselves, for better and worse.
★ Must-ReadMojo, the GPU-first language that looks like Python, is now fully open sourceModular released Mojo under Apache 2.0 on August 18. Mojo aims at the gap between Python, which is easy but slow, and CUDA, which is fast but hard and tied to NVIDIA. Code that looks like Python compiles to run directly on GPUs from more than one vendor. Open sourcing it is the difference between a bet on one company and a language you can adopt without asking permission.
ChatGPT now tries to detect teens and moves them to a locked-down modeStarting August 18, accounts OpenAI believes belong to 13 to 17 year olds get routed to a restricted ChatGPT: stronger blocks on self-harm, sexual and romantic content, and a parent-linked account that receives safety alerts. Parents still cannot read the chats. Rolling out over about two weeks. If you have kids using ChatGPT for homework, this changes what they see, and the age detection will sometimes guess wrong in both directions.
Meta shipped its first desktop app: a Mac assistant that can watch your screenFree, small, and in beta as of August 19. It can see what is on screen when you ask, and it takes dictation into any app. That screen-watching permission is the part to think about before installing it on a work machine: an assistant that can read your screen can read whatever a client left open in the next window.
📚 LearnRunning models locally with llama.cpp? Two of its ten new flaws are rated criticalTen vulnerabilities were disclosed in llama.cpp, the engine behind many self-hosted AI setups including parts of Ollama and LM Studio. The two worst, both in llama-server, scored 9.2 and 9.8 and allow remote code execution. Published earlier this month, so treat this as the patch reminder: if a llama-server is listening anywhere on your network, update it and make sure it is not exposed to the internet.
