🛠️ Technical Deep Dive
- •Architecture: Longxia utilizes a distilled MoE (Mixture of Experts) architecture designed for mobile NPU acceleration.
- •Quantization: Employs 4-bit integer quantization to fit within the memory constraints of mid-range mobile devices.
- •OpenClaw Integration: Acts as a dynamic routing layer that intercepts user queries and determines if processing occurs locally (Longxia) or via cloud-based models based on complexity.
