🪦 Needle 2: A 14MB Tool-Calling LLM That Solves a Problem You Don't Have

Let me write this review. Needle 2 is Cactus Compute’s answer to the question “what if we crammed a language model so small it fits in a smartwatch, but gave it laser focus on doing one thing: calling the right function with the right arguments?” Forty-five million parameters, compressed to 2 bits, baked into a single 14MB binary that runs a full inference session in 28MB of RAM. It’s trending because it genuinely is impressive—the engineering is tight, the benchmarks against other small models (FunctionGemma, LFM2.5, Apple FM) show it trades wins at 5x to 70x smaller, and the whole thing runs locally with zero cloud dependency. That’s the technical win. That’s also where I stop being excited. ...
