Spar — Train your thinking with AI

What it does

Most AI is trained to agree with you. Spar is the opposite — an adversarial debate partner that pushes back, questions your sources, and finds the holes in your thinking. Pick from 6 archetypes (Cross-Examiner, Socratic, Journalist, Executive, Ideologue, Friendly Saboteur), argue any topic across 5 rounds, and get a coaching report on where your thinking held and where it broke. For debaters, writers, founders, and anyone who needs to defend their thinking. Built to make you sharper, not happier

State a position you believe. Get attacked by AI opponents trained to destroy weak arguments. Get a coaching report showing exactly where you lost.

AI opponents built to expose weak arguments, test your logic, and make you unstoppable. You're performing well. Keep defending your position with stronger evidence. This app destroyed my ego in the best way possible. I think sharper now in every part of myfrom sparwithai.com

  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…
