Revievv

What it does

Most CAD review tools either cost $200+/month or are just viewers with no collaboration. Revievv does both - 3D STEP/STL viewer with design review built in. Pin comments directly on 3D model surfaces, not on screenshots. Share a link - reviewers don't need CAD software, an account, or any installation. Unlimited free reviewers on every plan, including the free tier. Everything runs in the browser. Upload a file, collect feedback, export annotated PDF. Takes 30 seconds to start.

  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…
