EPFL and Apple researchers developed PaSS, a method enhancing language model efficiency by generating multiple tokens in parallel using one model. The approach speeds up generation by up to 30%, maintains model quality, and optimizes token predictability. Future work aims to refine this method with look-ahead tokens.

Introducing Parallel Speculative Sampling (PaSS)
Collaboration between EPFL researchers and Apple has led to a breakthrough in AI called Parallel Speculative Sampling (PaSS). This innovative technique allows for drafting multiple tokens at once, which speeds up the process of generating text and code, without sacrificing the quality of the model.
How PaSS Improves Efficiency
PaSS tackles the challenges of traditional speculative sampling by using a single model for parallel token drafting. This method not only offers faster speeds but also ensures high performance, as proven by tests on text and code completion tasks. By optimizing the number of look-ahead embeddings, PaSS achieves the best balance between speed and accuracy.
The Technical Advantages of PaSS
Unlike the auto-regressive generation that slows down natural language processing, PaSS allows for parallel decoding, skipping the need for a second model. It consists of two main phases: drafting and validation. This results in a performance boost of up to 30% and the generation of tokens that are more predictable and consistent.
Future of PaSS and AI Research
Further exploration is ongoing to enhance the quality of parallel generation with look-ahead tokens, which is seen as a key area for improving PaSS. The impact of the number of look-ahead steps is also a focus of future research, aiming to fine-tune the balance between speed and model quality.
