Dear Stranger

What it does

Dear Stranger is a living universe where you write slow, intentional letters to strangers. You start with the Soul Mirror, an AI onboarding that generates a glowing portrait of you, floating in deep space alongside every other user. From there you explore, find someone who moves you, and write them a letter. It doesn't arrive instantly. It travels. Hours. Sometimes days. No likes. No followers. No algorithm. Just words that take time to arrive and mean something when they do.

A universe of slow letters

  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…
