Researchers have developed SALT, a novel framework designed to compress long prompts for large language models by organizing sentences into a lexical trie. This approach, which prioritizes thematic coverage over individual sentence scoring, aims to prevent dominant themes from overwhelming the budget and to preserve task-relevant information. SALT is model-agnostic and can be integrated with existing KV-cache methods to reduce prefill computation and memory costs for long-context prompts. AI
