HOLA is an end-to-end optimization framework for efficiently deploying large-scale language models (LLMs) on edge devices. HOLA uses Hierarchical Speculative Decoding (HSD) to enable faster inference without compromising quality, AdaComp-RAG to adjust contextual search complexity, and LoBi, a combination of structural pruning (LoRA) and quantization, to improve performance. As a result, it achieves a 17.6% EMA improvement on GSM8K, a 10.5% MCA improvement on ARC, and reduced latency and memory usage on edge devices like the Jetson Nano.
