Ask HN: What AI agents have you built?
Just curious about how people are using AI agents for their personal (or commercial) use. And which models you are using. I made this agent to tutor physics with diagrams! It's basic and my first agent and actually only has a single tool to call, but I really enjoyed building the agent loop from scratch rather than using a framework. Uses 4.1 for fast but reasonably intelligent, then o3 I think for diagram generation. A smart RSS reader that filters 110 feeds down to what I can handle. A whatsapp responder
