hackernews🔗 Show HN: Needle: We Distilled Gemini Tool Calling into a 26M Model 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.<p>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-assem 👍 768 💬 210 🔗 https://github.com/cactus-compute/needle
