Low-Bit Quantization for LLMs on Edge Devices
Low-bit quantization is enabling large language models (LLMs) to run efficiently on everyday devices like smartphones and IoT gadgets. By reducing the precision of model weights and activations to formats like INT8 or INT4, it drastically cuts memory usage, improves speed, and lowers energy consumption - all critical for devices with limited resources. Key takeaways: Recent advancements, such as lookup table (LUT)-based computation and tools like T-MAC and Ladder , are further improving efficiency. Challenges remain in balancing accuracy with extreme compression, but ongoing developments in hardware and algorithms are addressing these hurdles.
