Show HN: Lunon – Instant model switching across LLMs https://ift.tt/b89BAdw

Show HN: Lunon – Instant model switching across LLMs Hey HN! We built Lunon to make LLM development way less of a headache. Ever wanted to see how different models handle the same prompt without all the setup hassle? That's what we fixed. Our API lets you compare Claude, GPT, Mistral and others in real-time with just a few lines of code. No more complex infrastructure or managing multiple API connections - we handle all that boring stuff behind the scenes. Plus, you can cut costs by intelligently routing requests to the right model for each task. Use the powerful (expensive) models only when you really need them. If you're building with LLMs and tired of the integration headaches, would love to hear feedback! https://lunon.com/ April 11, 2025 at 11:46PM

Show HN: I built a tool to manage and compare credit card rewards https://ift.tt/mVTsP9Y

Show HN: I built a tool to manage and compare credit card rewards This is a free tool that helps you manage and visualize your credit card rewards across different categories. You can input the cards in your wallet and see how they complement each other, spot gaps in your setup, and also see the best card to use for a given merchant. I’m also a founder at OneCard, where we’re building a smart card that’ll eventually handle all of this automatically, routing each purchase to the best card in real-time. Would love feedback from the HN community! https://ift.tt/wZkp8d1 April 11, 2025 at 02:54AM
