What it does
CH3 music editor is a text-driven music language designed to let you compose entirely by musical intuition. Describe complex patterns, transpositions, and timing in highly readable plain text. To remove text abstraction, the editor offers smart assistance: Circle of Fifths highlighting for harmonic relations, temporal sync highlighting to align multi-part symbols, and instant cursor audio feedback. With an in-browser engine, it’s an intuitive workflow for all music creators.
Start writing music in the browser, then go deeper with interactive playback and analysis. Create, explore, and understand musical content with ch3.

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…
