Report #95847

[architecture] Assuming large context windows \(e.g., 128k tokens\) eliminate the need for external memory architecture.

Use external memory for state persistence and retrieval, reserving the large context window for the current complex task. Apply a working memory budget that strictly limits injected memory to a fraction of the total window.

Journey Context:
The 'Lost in the middle' phenomenon shows LLMs fail to reliably use information in the middle of long contexts. Cramming 100k tokens of history into the context window degrades reasoning, increases latency, and costs a fortune. External memory allows targeted retrieval, keeping the active context small and highly relevant.
