Cactus released Needle2, a 14MB agentic language model designed to run on phones, wearables, smart home devices, and robots. The model executes full sessions in 28MB of RAM with 45 million parameters compressed at 2-bit.

Needle2 builds on the original Cactus Needle, incorporating community feedback from its Hacker News debut. The model achieves 500 tokens per second decode speed on a Raspberry Pi 5, making it practical for real-time applications on resource-constrained hardware. The single 14MB binary handles tool calling, device control, and structured data extraction—core capabilities for agentic workflows. Its small footprint enables deployment across diverse edge environments without requiring cloud connectivity. The compressed architecture addresses a critical gap in on-device AI, where existing language models typically demand gigabytes of storage and memory. Needle2's efficiency opens possibilities for autonomous agents running directly on consumer hardware, from household IoT devices to small robots, without relying on external servers.
