CardQuest

What it does

CardQuest turns your credit card portfolio into an RPG. Add your cards, level up your player, and unlock combo bonuses when you build legendary setups like the Chase Holy Trinity or Amex Trifecta. Instead of staring at a spreadsheet, you get a visual way to see what you have, what you're missing, and what to pick up next. Built by a churner, for churners.

  I built a tool to manage and compare credit card rewards2025 · rewards.getonecard.io · ▲87

  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!

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
