Good morning, Diego. Here’s your AI briefing for Tuesday, July twenty-eighth.

The strongest official signal today comes from OpenAI. It published new research on how people are using ChatGPT at work, and the headline is not simply “more productivity.” OpenAI says usage is increasingly crossing job boundaries: people are asking ChatGPT to help with tasks normally associated with other roles. That matters because it points to AI as a re-bundling tool inside companies, not just a faster autocomplete. The awkward management question is now: if everyone can borrow a little bit of everyone else’s workflow, who actually owns the process?

Anthropic had a less flattering day. TechCrunch and The Decoder reported that some shared Claude chats and Artifacts appeared in Google search results. The issue seems tied to public share links that were not kept out of search indexing. Anthropic reportedly disabled indexing after the reports. The takeaway is simple and boring, therefore important: “share” does not mean “private,” and teams should treat public AI-chat links like public documents, because the internet remains undefeated at finding things you hoped it would not find.

On the Google front, new data reported by TechCrunch says AI Overviews now appear in about forty-three percent of Google searches. That is a huge distribution shift. Even if publishers and SEOs are tired of hearing about answer engines, users are already being trained to accept AI summaries as the front door to the web. For companies, the practical question is moving from “how do we rank?” to “how do we become a cited source inside the answer?”

In broader AI infrastructure, Nvidia and Microsoft launched the Open Secure AI Alliance with partners including IBM and SpaceX, according to The Verge. Notably absent: OpenAI, Google, and Anthropic. The alliance is focused on open-source tools for securing AI systems, which is timely after recent agent-security drama. Translation: the AI stack is becoming critical infrastructure, and the security layer is still being invented in public.

Finally, keep an eye on China’s open-weight race. The Decoder reports Moonshot AI released Kimi K3 weights and parts of its infrastructure after strong frontier-model benchmark claims. Independent testing still shows gaps, especially in cyber and math, but the strategic point stands: open-weight models are becoming a geopolitical product strategy, not just a GitHub hobby.

Bottom line: today was less about shiny demos and more about deployment reality — work practices, privacy defaults, search distribution, security, and open-model competition. In other words, the plumbing is news now. Sorry, plumbing.
