CircadiaOS

What it does

CircadiaOS is software-only sleep optimization. No mattress pod, no proprietary sensor, no new hardware. It connects the wearable and smart thermostat you already own, builds a personalized overnight temperature schedule from your biometrics, and runs your thermostat through it automatically every night. Most premium sleep tech in this category has been hardware-first: thousand-dollar mattress pods, dedicated sensors, custom firmware. We took the opposite bet.

CircadiaOS is an iOS app that connects sleep trackers (Oura, Whoop, Apple Watch, Garmin, Fitbit) to smart thermostats and automatically adjusts your bedroom to a personalized nightly temperature curve to improve sleep quality.

  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…
