Researchers have developed a new method for controlling language generation in multilingual large language models using sparse autoencoders (SAEs). This approach improves cross-lingual representation and offers more reliable language control compared to existing methods that often rely on English-only data and heuristic layer selection. The new technique introduces a principled rule for selecting intervention layers based on multilingual alignment and language separability, which was tested on LLaMA-3.1-8B and Gemma-2-9B models for tasks like machine translation and cross-lingual summarization.
