who's comin?
Excited to host a real-time voice AI hackathon at YC's office on 10/11 with @pipecat_ai @GoogleDeepMind @boundaryML @covaldev @langfuse @heytavus Sign up here: events.ycombinator.com/pipecat-gemini… We'll offer guaranteed YC interviews to the winners
These guys dropped an absolute masterclass on AI agents. No hype. No n8n spaghetti. Just practical agent building, explained in away that anyone can understand. Thanks @dexhorthy and @hellovai. AI That Works is quickly becoming the best AI content on the Internet.
Working at AI startups in 2025 is like: > Decides to write compiler from scratch in Rust 🤷🏻 > 3 lines of code reveal complicated edge case 🤔 > CEO @hellovai wakes up at 5 AM to talk about Leetcode ultra-hard graph algorithms for 2 hours 🕜 > Goes back to sleep 💤 😂

LinkedIn needs some BAML
It's delightful how easy it is to deploy working prompt injection attacks via LinkedIn
English is not and will never be a good programming language. Facts.
If LLMs are a new kind of compilers, will we get: 1. New high-level programming / spec languages? (sorry, English is not and will never be a good programming language), 2. New low-level target intermediate languages?
🎯 SUNDAY REMINDER: 3 days until Coding Agents meetup! Here's what happens Tuesday 6 PM at GitHub HQ: → Container-use demo (safe agent development) @sam_alba → BAML intro (typed prompts!) @hellovai → Real experimental projects @grahammcbain → Panel + deep networking Recent…

me and @hellovai dropped some tips on context engineering when using coding agents - this is super dense but a great watch
OpenAI need some BAML .... 🤔🤔
why does openai serialize types wrong in their models? you write integer, but they put in number. clearly float vs numbers matter... and then its any other times?? I guess its good they opensourced their serializer, but wild that they use jinja to serialize types.
