💬 Summary
What started as a sharing feature turned into an unexpected SEO exposure. Over 100,000 ChatGPT chats were publicly accessible, some indexed, and many archived long before OpenAI responded. It all started with something simple: a “Share” button When OpenAI let people share ChatGPT conversations publicly, it probably felt like a helpful feature. You click, get a clean link, and show off a cool prompt or funny exchange. But tucked behind that button was a small checkbox. “Make this chat discoverable” And that changed everything. People clicked without fully thinking it through. And just like that, thousands of ChatGPT chats ended up in Google search results. These weren’t private links anymore. They were public pages, visible to anyone. Some were harmless....

💬 Summary
The ChatGPT sharing dialog demonstrates how difficult it is to design privacy preferences ChatGPT just removed their “make this chat discoverable” sharing feature, after it turned out a material volume of users had inadvertantly made their private chats available via Google search. Dane Stuckey, CISO for OpenAI, on Twitter: We just removed a feature from @ChatGPTapp that allowed users to make their conversations discoverable by search engines, such as Google. This was a short-lived experiment to help people discover useful conversations. [...] Ultimately we think this feature introduced too many opportunities for folks to accidentally share things they didn’t intend to, so we’re removing the option. There’s been some media coverage of this issue—here are examples from TechCrunch, TechRadar, and...

💬 Summary
Apple is hiring engineers for an "Answers, Knowledge, and Information" team that is working on improving Siri, Spotlight, Safari, and more. As of writing, Apple's careers website has more than a dozen job listings for the team across the U.S. and China. For example, Apple is looking to hire a Staff Machine Learning Engineer to help with "improving Siri's ability to answer personal domain questions." The job listing says the team develops large language models that are "responsible for answering users' questions using their personal documents with privacy at the forefront." That sounds a lot like Apple's personalized Siri features, which were delayed until 2026. However, Bloomberg's Mark Gurman says there is more at play here. In his Power On...
🗣️ Post 5: Interview with ChatGPT Agent Creators

💬 Summary
Contents Isa Fulford: I think this model is actually very good at multi-turn conversations, and it’s very nice to continue working on a task with it. I think that’s one of the deficiencies of Deep Research. A lot of people will do multiple Deep Research requests in a single conversation, but it doesn’t always work so well, so I think we’re really happy with this model’s multi-turnability, and we just want to improve even further. And then I also think personalization and memory for agents will also be very important, and right now every agent task is initiated by the user, but in future it should also be doing things for you without you having to even ask in the...
