A public journal for builders to think out loud.

a small, honest place for builders to post WIPs, half-baked ideas, and the chaos between it all. like texting a friend at 11:58pm. there's no threads. no metrics. no corporate voices... just the the parts of building that don't make it into the launch post. a post composer designed for train-of-thoughts, not threads. lowercase by default. no drafts queue, no scheduling, no thought-leadership prompts. hit Ship and move on. replies are soft lavender bubbles... closer to iMessage than to a threads of strangers beefing on the internet. people stick around for a project; not a performance. following someone on Serendipity is following their builds: the bug at 2am, the thing that worked, the…from joinserendipity.co

  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…
