Right, here's the thing: If you are using AirPods(or any Bluetooth headphones with a mic in fact) on Mac and something activates the mic(i.e. you Shazam a song), the sound will be interrupted momentarily and will return in very low quality. This is happening because Bluetooth can't handle both way high quality streaming and the bandwidth is decreased to make it work.

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…
