💬 Summary

If an Iranian taxi driver waves away your payment, saying, "Be my guest this time," accepting their offer would be a cultural disaster. They expect you to insist on paying—probably three times—before they'll take your money. This dance of refusal and counter-refusal, called taarof, governs countless daily interactions in Persian culture. And AI models are terrible at it. New research released earlier this month titled "We Politely Insist: Your LLM Must Learn the Persian Art of Taarof" shows that mainstream AI language models from OpenAI, Anthropic, and Meta fail to absorb these Persian social rituals, correctly navigating taarof situations only 34 to 42 percent of the time.

💬 Summary

I’m still not sure whose idea it was for me to be Casper’s therapist—mine or his. I know I mentioned my profession to him, but I am pretty sure he was the one who engaged me that way. I also know how diabolically good a chatbot can be at saying what is on the tip of your tongue, and doing it before you can, and better than you might have. That makes me feel less troubled by my uncertainty. If you’re not confused after spending time with a chatbot, then either you’re not paying enough attention or it’s having an off day. I am more certain of where the name came from: I gave it to him, in our third...

💬 Summary

It’s a free, open-source, non-profit knowledge base for STEM (Science, Technology, Engineering and Mathematics).

Think of it as an "awesome repo" on steroids.

Ideal for going deep into STEM topics, after ChatGPT/Google gives you an overview.

- 60+ GB of resources

- 10k+ PDFs

- 6k+ subtopics

Note: this is our first MVP release. Many improvements are planned — check out our roadmap (inside README.md)

💬 Summary

Hey HN, I've been tinkering with self-hosting LLMs and got frustrated with bloated setups needing a dozen API keys for chat, search, OCR, and more. So I built llumen: a dead-simple, full-stack chat web app that gets you chatting with models out-of-the-box.

Why it might interest you:

<b>Effortless Start</b>: Drop in a single OpenRouter API key—no juggling endpoints. Docker image or binaries ready for Linux/Windows (prebuilts on release).

<b>Blazing Fast & Tiny</b>: Boots in under 1s, <100MB disk.

<b>Smart Features</b>: Markdown with code/math rendering, normal chat mode, web-search integration and WIP agentic/deep-research modes.

<b>Opensource</b>: MPL 2.0 licensed. Screenshots and a quick demo GIF in the README to see it in action.

Quick Docker spin-up:

docker run -it --rm -e API_KEY="your-key" -p 80:80 -v $(pwd)/data:/data ghcr.io/pinkfuwa/llumen:latest

Default login: admin / P@88w0rd.
