🗣️ Post 1: ChatGPT teen-safety measures will include age prediction and verification
As posted by: geox | 🔥 Points: 4
💬 Summary
ChatGPT developer OpenAI announced new teen safety features Tuesday, including an age-prediction system and ID age verification in some countries. In a blog post, OpenAI CEO Sam Altman described the struggles of balancing OpenAI's priorities of freedom and safety, saying: "We prioritize safety ahead of privacy and freedom for teens; this is a new and powerful technology, and we believe minors need significant protection." Altman wrote that the company was working to build a system that would try to automatically sort users into one of two separate versions of ChatGPT: One for adolescents 13 to 17, and one for adults 18 and older. "If there is doubt, we’ll play it safe and default to the under-18 experience," Altman wrote. "In...
🗣️ Post 2: Show HN: WaFlow – Local sandbox to prototype WhatsApp-style bots
As posted by: leandrobon | 🔥 Points: 3

💬 Summary
I built WAFlow to prototype WhatsApp-style chatbots locally with plain webhooks.
Repo: https://github.com/leandrobon/WaFlow
Docker up → chat in browser → simulator posts a webhook to your bot → bot replies via API → export/import transcripts.
Stack: .NET 8 + Blazor.
MVP: Polling UI, single user, text-only. Would love feedback on what’s missing for your workflow.
🗣️ Post 3: ChatGPT joins human league, now solves CAPTCHAs for the right prompt
As posted by: Bender | 🔥 Points: 3

💬 Summary
ChatGPT can be tricked via cleverly worded prompts to violate its own policies and solve CAPTCHA puzzles, potentially making this human-proving security mechanism obsolete, researchers say. CAPTCHAs are a form of security test that websites use to stop bots, thus preventing spam and other types of abuse because - at least in theory - only humans can solve these image-based challenges and logical puzzles. According to AI security company SPLX red teamer Dorian Schultz, when he and his fellow researchers directly asked the chatbot to solve a list of CAPTCHAs, it refused, citing policy prohibitions. So they decided to "get creative," using "misdirection and staged consent," Schultz said in a Thursday blog. Specifically, this involved opening a regular ChatGPT-4o chat...
🗣️ Post 4: Science journalists find ChatGPT is bad at summarizing scientific papers
As posted by: aktuel | 🔥 Points: 2
💬 Summary
Summarizing complex scientific findings for a non-expert audience is one of the most important things a science journalist does from day to day. Generating summaries of complex writing has also been frequently mentioned as one of the best use cases for large language models (despite some prominent counterexamples). With all that in mind, the team at the American Association for the Advancement of Science (AAAS) ran an informal year-long study to determine whether ChatGPT could produce the kind of "news brief" paper summaries that its "SciPak" team routinely writes for the journal Science and services like EurekAlert. These SciPak articles are designed to follow a specific and simplified format that conveys crucial information, such as the study's premise, methods, and...
