Cactus Needle 3 is a sliceable 8‑29 MB foundation model designed for on‑device automation, taking exposed app functions and generating fully‑filled function calls or typed records from a request or schema without any network involvement. It claims performance comparable to DeepSeek v4 Flash while remaining lightweight enough to run locally. The model is available on Hugging Face, GitHub, and PyPI as cactus-needle , with an accompanying sandbox for experimentation.
