The Takeaway

Current agent memory is usually tied to a specific model's style; this work allows heterogeneous agent swarms (e.g., GPT-4 and Claude) to utilize a shared pool of past experiences, improving efficiency and collective performance.

From the abstract

Large language model (LLM)-based agents rely on memory mechanisms to reuse knowledge from past problem-solving experiences. Existing approaches typically construct memory in a per-agent manner, tightly coupling stored knowledge to a single model's reasoning style. In modern deployments with heterogeneous agents, a natural question arises: can a single memory system be shared across different models? We found that naively transferring memory between agents often degrades performance, as such memo
