The Agent Summarizes Its Memory One Slot at a Time—Together
SpecCompact drafts structured context slots in parallel, then has the target model verify and repair each proposed line.
Summary
SpecCompact drafts structured context slots in parallel, then has the target model verify and repair each proposed line.
A small tuned drafter generates independent summary slots while the target model accepts or repairs lines and feeds the updated prefix into later work. Across AppWorld and tau-cubed with two target models, the system reports 2.04 to 5.63 times faster compaction than Hermes-style summarization. A Hermes user study records an 8.68 times median speedup. Downstream quality varies by model and task, so the result is a latency technique with measured tradeoffs, not lossless memory compression.
