Evolutionary thought caching for multi-stage language model systems

Abstract

A system and method for efficient natural language processing combines large and small language models with a reasoning cache architecture. Input data is processed by a first large language model to generate structured thoughts with associated latent representations, which are cached for future use. Specialized agents perform domain-specific operations on cached thoughts and collaboratively evolve them using genetic algorithms. When new input is received, similar cached or evolved thoughts are retrieved based on latent representation similarity. The input and retrieved thoughts are then routed to a second, smaller language model to generate a response. This architecture reduces computational overhead while preserving response quality, enables reuse of reasoning across sessions and devices, and extends effective context beyond traditional sequence limits. By leveraging prior reasoning, the system minimizes redundant computation and supports scalable deployment across diverse hardware environments.
