The key innovation is the ARCHIVAL system that actively prunes memories without deleting them - they can be recovered later.

Benchmark results:\n- LongMemEval EM 54.2% / judge 83.3%\n- 16KB budget +8.3pp improvement\n- Tool compression -95.5%

I'm curious about others' experiences with:\n1. Memory consolidation approaches (episodic→semantic→core)\n2. Spaced repetition for AI agents\n3. Active forgetting/pruning strategies

Perhaps for high-token tasks, first an automated search of prior work within the firm, parsing what's already done or not done, and only prompting AI for the new components, then assembling the components before serving to the user.

If lengthy components were already done. the overall output might be faster.

I wonder how much of that is moving over to things like cowork or codex type apps.
