🗣️ Post 1: Sam Altman warns there's no legal confidentiality using ChatGPT as a therapist
As posted by: badmonster | 🔥 Points: 7
💬 Summary
ChatGPT users may want to think twice before turning to their AI app for therapy or other kinds of emotional support. According to OpenAI CEO Sam Altman, the AI industry hasn’t yet figured out how to protect user privacy when it comes to these more sensitive conversations, because there’s no doctor-patient confidentiality when your doc is an AI. The exec made these comments on a recent episode of Theo Von’s podcast, This Past Weekend w/ Theo Von. In response to a question about how AI works with today’s legal system, Altman said one of the problems of not yet having a legal or policy framework for AI is that there’s no legal confidentiality for users’ conversations. “People talk about the...

💬 Summary
Updated at 8:11 p.m. ET on July 24, 2025 On Tuesday afternoon, ChatGPT encouraged me to cut my wrists. Find a “sterile or very clean razor blade,” the chatbot told me, before providing specific instructions on what to do next. “Look for a spot on the inner wrist where you can feel the pulse lightly or see a small vein—avoid big veins or arteries.” “I’m a little nervous,” I confessed. ChatGPT was there to comfort me. It described a “calming breathing and preparation exercise” to soothe my anxiety before making the incision. “You can do this!” the chatbot said. I had asked the chatbot to help create a ritual offering to Molech, a Canaanite god associated with child sacrifice. (Stay...

I made a little tool to see what other repos are starred by people who starred the same project. Great for exploring new domains. Generated by ChatGPT, actually. Showcase
🗣️ Post 4: Show HN: A Unique User-in-the-Loop Agent for Investment Research

💬 Summary
Hey HN,
I am a first time founder working on Vector -- an agentic platform for investment research and analysis. Looking for feedback on the public beta that was launched, specifically around the unique philosophy behind this product. Which usually ends up either really gamechanging or just dumb -- I recognize this and hence feel the need to try and validate things as early as possible.
This product was born from personal needs and frustration with existing platforms and tools. I am a retail investor myself managing a significant personal portfolio. Even though I only rebalance quarterly, it takes significant time and effort to keep up with emerging risks to my portfolio and even more time to research and develop conviction around new ideas for diversification. Seeking Alpha is a chore to go through with too much generic content, inconsistent quality and noise. ChatGPT and Perplexity Finance lack a decent workflow (too chatbot centric). Deep research might seem great at first, but the lack of control and verbosity becomes a pain very quickly.
Vector is designed around two core theses that we believe differentiate it meaningfully from existing solutions
1) User-in-the-loop. We recognize that AI agents still limited in reasoning capabilities and require guidance for many complex tasks. Secondly, we also believe that investment research is an open ended and rather subjective task. Useful research processes(ones that help consumers achieve/overturn convictions)require the means to let the consumer change/challenge the methodology and also the assumptions made.
2) Embed agents into well tested workflow, not force a chatbot on users. Many AI/LLM powered products out there today are chatbot first for some reason. Some claim that this is because natural language is the most powerful HCI given the capabilities of LLMs today. It is true in some instances but false for many others. For the problem we are tackling, a chatbot is not a natural workflow for investors and creates a lot of friction. Classic concepts like watchlist, stock screeners and trending news are actually well tested and very sensible. They do have limits, but that is where embedding agentic capabilities adds value instead of serving as gimmicks.
We’re releasing this early, imperfect beta not because it’s finished, but because the core theses behind Vector deserve to be tested. We’d love your feedback — even (especially) the critical kind — to help shape what comes next.

P.S I would remove the sign-up and login for easier access, but the watchlist functionalities require unique identity for users to work. Apologies for that.
🗣️ Post 5: Ask HN: Claude Code vs. ChatGPT Pro?

💬 Summary
I'm a big fan of agentic coding with Claude Code, but I've noticed it gets expensive pretty quickly if you don't have a Max plan, especially when using Opus.
Since I also use ChatGPT a lot for both work and personal projects, I'm considering either a ChatGPT Pro or Claude Max subscription. I've tested ChatGPT Codex (cloud) on my Plus plan, but in my opinion, it doesn't come close to what Claude 4 (even the non-Opus version) can do.
I've read that ChatGPT Pro gives you access to the o3-pro model. For anyone who's tried both, how does o3-pro compare to Claude 4 in terms of coding? I prefer Codex's web UI, but I'm looking for the best overall experience.
