HeadInfer

HeadInfer: Memory-Efficient LLM Inference

HeadInfer is an innovative framework designed to optimize memory usage for large language model (LLM) inference. By utilizing a unique head-wise offloading strategy, it enables significantly reduced GPU memory consumption, allowing for efficient processing even on consumer-grade GPUs.

Key Features:

• Memory Optimization: Implements head-wise KV cache offloading, fine-tuning memory usage for long-context inference.
• High Token Processing: Capable of processing up to 4 million tokens on consumer GPUs, making it ideal for extensive contexts.
• Asynchronous Data Transfer: Uses overlapping computation with offloading to minimize any performance bottlenecks.
• Compatibility: Works seamlessly with major LLMs such as LLaMA, Mistral, Qwen, and more.
• Easy Integration: Requires minimal changes to existing inference frameworks, facilitating simple integration with Hugging Face models.

Benefits:

• Cost-Effective: Significantly reduces the cost of running large models on standard hardware by minimizing memory requirements.
• Research Ready: A valuable tool for researchers in AI and machine learning, enhancing efficiency in model inference scenarios.

HeadInfer is perfect for developers and researchers looking to leverage large language models without the substantial hardware demands typically associated with them.
