Generative Large Language Models (LLMs) have shown outstanding performance in various tasks. An effective LLM inference system, PowerInfer, designed for local deployments using a single consumer-grade GPU, significantly boosts LLM inference speed, achieving up to 11.69 times faster performance than the current system. This introduces a potential solution for advanced language model execution on desktop PCs with constrained GPU capabilities.

Meet PowerInfer: A Fast Large Language Model (LLM) on a Single Consumer-Grade GPU that Speeds up Machine Learning Model Inference By 11 Times
Generative Large Language Models (LLMs) have shown remarkable performance in tasks like Natural Language Processing (NLP), creative writing, question answering, and code generation. Now, these models can be run on home PCs with consumer-grade GPUs, offering improved data privacy, customizable models, and lower inference costs.
Challenges and Solutions
Local installations prioritize low latency, but implementing LLMs on consumer-grade GPUs can be challenging due to high memory requirements. To address this, strategies like offloading and model compression are being used.
In a recent study, researchers introduced PowerInfer, an effective LLM inference system designed for local deployments using a single consumer-grade GPU. PowerInfer reduces the need for expensive data transfers and optimizes performance by preloading hot-activated neurons onto the GPU for instant access.
Key Features of PowerInfer
- Utilizes high locality in LLM inference to reduce GPU memory requirements
- Integrates neuron-aware sparse operators and adaptive predictors for further optimization
- Delivers impressive token creation rates and peak performance using mainstream hardware
