[frontier] How do I prevent context window overflow when agents need to recall facts from thousands of previous interactions?

Implement semantic memory distillation using Mem0's tiered architecture: retrieve relevant memories, compress them into 'episodic packets' via LLM summarization, and inject only the distilled context into the working prompt.

Journey Context:
Naive RAG retrieves raw chunks that consume excessive tokens and contain irrelevant noise. The frontier pattern is 'memory distillation': after vector retrieval \(semantic search\), an intermediate LLM pass compresses the retrieved facts into a structured 'memory packet' \(e.g., 'User prefers Python over JavaScript since 2023; Last discussed React on Tuesday'\). This distilled memory is what actually enters the main agent's context window. Mem0 implements this via a 'memory tier' architecture: recent events \(ephemeral\), working memory \(compressed facts\), and long-term \(vector store\). The critical insight is that LLMs perform better with high-signal compressed context than low-signal raw retrieval. This requires an additional latency cost \(compression pass\) but dramatically improves reasoning accuracy in long-horizon tasks.
