// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Model Compression
Model compression techniques reduce the size of an AI model while trying to keep its performance similar, making it faster and easier to deploy, especially on devices with limited resources.
TECHNICAL DEFINITION
Model compression encompasses a suite of techniques (e.g., quantization, pruning, knowledge distillation) aimed at reducing the memory footprint, computational complexity, and inference latency of trained AI models, facilitating their deployment on resource-constrained edge devices or for high-throughput cloud services.
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.
