The Mamba in the Llama: Accelerating Inference with Speculative Decoding

Practical Solutions for Efficient Language Models

Challenges in Language Models

Large Language Models (LLMs) face challenges in handling very long sequences due to their quadratic complexity relative to sequence length and substantial key-value (KV) cache requirements. This impacts efficiency during inference, hindering the development of applications that require reasoning over multiple long documents, processing large codebases, or modeling complex environments.

Efficient Architectures and Techniques

Researchers have explored various approaches to address the efficiency challenges in LLMs, including attention-free models, distillation techniques, and speculative decoding. These approaches aim to reduce computational demands while maintaining or surpassing the performance of Transformers.

Unique Approach for Efficient LLMs

Researchers propose a unique approach to mitigate the efficiency challenges of LLM models by distilling a pre-trained Transformer into a linear RNN. This method aims to preserve generation quality while significantly improving inference speed. The proposed technique involves mapping Transformer weights to a modified Mamba architecture, introducing a multistage distillation pipeline, and developing a hardware-aware speculative sampling algorithm for efficient inference.

Performance and Efficiency of Hybrid Models

The distilled hybrid Mamba models demonstrate competitive performance on various benchmarks, offering a good balance between efficiency and performance. They achieve comparable or better performance than their teacher models on chat tasks and general language understanding, while also showcasing promising results in speculative decoding experiments.
