// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Quantization
Quantization is a model compression technique that reduces the precision of numbers used in an AI model, for example, by storing them with fewer bits, which makes the model smaller and faster.
TECHNICAL DEFINITION
Quantization is a model compression technique that reduces the numerical precision of model parameters (weights) and activations, typically from floating-point (e.g., FP32) to lower-bit integer formats (e.g., INT8), thereby decreasing memory footprint, accelerating inference, and improving energy efficiency, often with minimal accuracy loss.
BACKGROUND
A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation. LLMs can typically generate, summarize, translate and analyze text in many contexts, and are a foundational technology behind modern chatbots. Biased or inaccurate training data can make an LLM's output less reliable.
