aiqbench analysis
This release marks a significant step in edge AI by demonstrating that specialized tool-calling tasks can be executed on constrained hardware like Raspberry Pis and smartphones without GPUs or NPUs. The model's efficiency, achieved through quantization to CQ2-bit and a custom Simple Attention Network architecture, enables fully offline sessions within 28MB of RAM for specific device control and data extraction workflows.
Meet Needle 2: An Open 45M-Parameter Tool-Calling Model That Ships as a 14MB Binary and Runs a Full Session in 28MB of RAM

Cactus Compute released Needle 2, an open 45M-parameter model for tool calling, device use, and structured extraction. The full model is a single 14MB binary that runs a session in about 28MB of RAM. It leads both Seal-Tools splits while targeting hardware with no GPU and no NPU.

Cactus Compute has released Needle 2, an open 45M-parameter model for tool calling, device use, and structured extraction. The entire model ships as a single 14MB binary that runs a full session in about 28MB of RAM. Weights are trained and deployed at CQ2-bit using Cactus Quants, and the model is sealed inside the company’s own C++ engine, so there is no runtime to install and no download at inference time. Reported decode throughput is 500 tokens/sec on a Raspberry Pi…
