Needle 3 fits an AI agent into 8 MB
Cactus just rolled out Needle 3, a tiny foundation model packed into a single 8–29 MB binary for smartwatches and microcontrollers. It trades general chat capacity to excel at offline tool calls and data extraction, scaling from 2 to 20 layers based on hardware limits. Why it matters: developers can now build instant, fully offline actions directly on tiny edge devices without relying on the cloud.
