Report #43103

[synthesis] Chat interfaces degrade in quality over long sessions because older, relevant context is truncated or pushed out of the context window by newer turns

Run an asynchronous background model on past conversation turns to extract structured key-value memories or summaries, injecting them into the system prompt of future turns instead of keeping the raw history.

Journey Context:
The naive approach to long context is just filling up the 200k window. However, attention mechanisms degrade with dense, irrelevant context \(needle-in-haystack problem\). ChatGPT's Memory feature and Claude's architecture handle this by running a cheap, fast model asynchronously on previous turns. It extracts facts into a structured list. The main model then receives this compressed, high-signal summary in its system prompt, while the raw old turns are dropped. This optimizes cost and maximizes attention density.
