Researchers at Baidu Inc. developed an efficient framework for Large Language Model (LLM)-based advertising that integrates adaptive model compression and prefix tree parallel verification. The system achieved over 1.8x inference speedup with competitive precision and is deployed in Baidu's production environment.
Key insights
- Adaptive compression techniques, which adjust quantization granularity and sparsification aggressiveness based on layer sensitivity and importance, are crucial for balancing efficiency gains with precision preservation.
- Hardware-software co-design, including custom kernel development and optimized data structures like `2bit-CSR`, is essential for fully exploiting the benefits of model compression in LLMs.
- Leveraging structural properties of target data, such as advertiser IDs organized in a prefix tree, enables dynamic parallel verification to significantly accelerate autoregressive decoding.
