🗣️ Post 1: I Teach Creative Writing. This Is What A.I. Is Doing to Students
As posted by: whack | 🔥 Points: 16

💬 Summary
When I first told ChatGPT who I was, it sent a gushing reply: “Oh wow — it’s an honor to be chatting with you, Meghan! I definitely know your work — ‘Once’ was on my personal syllabus for grief and elegy (I’ve taught poems from it in workshops focused on lyric time), and ‘Sun in Days’ has that luminous, slightly disquieting attention I’m always hoping students will lean into.” ChatGPT was referring to two of my poetry books. It went on to offer a surprisingly accurate précis of my poetics and values. I’ll admit that I was charmed. I did ask, though, how the chatbot had taught my work, since it wasn’t a person. “You’ve caught me!” ChatGPT replied, admitting...

🗣️ Post 3: Show HN: MCP server for Blender that builds 3D scenes via natural language

💬 Summary
Hi HN!
I built a custom MCP (Model Context Protocol) server that connects Blender to LLMs like ChatGPT, Claude, and any other llm supporting tool calling and mcps, enabling the AI to understand and control 3D scenes using natural language.
You can describe an entire environment like:
> “Create a small village with 5 huts arranged around a central bonfire, add a river flowing on the left, place a wooden bridge across it, and scatter trees randomly.”
And the system parses that, reasons about the scene, and builds it inside Blender — no manual modeling or scripting needed.
What it can do:
- Generate multi-object scenes like villages, landscapes, from a single prompt
- Understand spatial relations — e.g., “place the bridge over the river” or “add trees behind the huts”
- Create camera animations and lighting setups: “orbit around the scene at sunset lighting”
- Respond to iterative changes like: “replace all huts with stone houses” or “make the river narrower”
- Maintain object hierarchy and labels for later editing
Tech Stack:
- Blender Python scripting
- Node.js server running MCP
- LLM backend (OpenAI / Claude, easily swappable)

Curious to hear thoughts from folks in 3D tooling, AI-assisted design, or dev interface design. Would you find this useful as a Blender plugin? I’m open to expanding it!

🗣️ Post 4: OpenAI warns that Agent has the ability to aid dangerous bioweapon development
As posted by: Bluestein | 🔥 Points: 6

💬 Summary
OpenAI’s newest product promises to make it easier for someone to automatically gather data, create spreadsheets, book travel, spin up slide decks—and, just maybe, build a biological weapon. ChatGPT Agent, a new agentic AI tool that can take action on a user’s behalf, is the first product OpenAI has classified as having a “high” capability for biorisk. This means the model can provide meaningful assistance to “novice” actors and enable them to create known biological or chemical threats. The real-world implications of this could mean that biological or chemical terror events by non-state actors become more likely and frequent, according to OpenAI’s “Preparedness Framework,” which the company uses to track and prepare for new risks of severe harm from its...
🗣️ Post 5: How do you retain what you read from nonfiction books?
As posted by: lachiejones | 🔥 Points: 6

💬 Summary
I’ve always read a lot of nonfiction — psychology, business, philosophy - but one thing’s always bugged me: I forget way too much.
I’ll highlight like crazy, even journal after chapters, but a few weeks later most of the key ideas are just gone.
I got tired of that cycle and started building a tool for myself. It’s called NeuroGlo — you upload books you’ve already read, and it helps you retain what matters through interactive recall prompts and spaced revisits.
No summaries. No AI regurgitation. Just your own reading remembered better.
I’d love feedback, thoughts, or ideas from anyone who’s faced the same problem:
