DeepSeek: More memory is not always better for agents: evaluation of eight models shows dosage should be calibrated by capability

Agent memory is not a feature to switch on casually; its dose must be calibrated to model capability. Strong models are better suited to injecting a full set of guides, with DeepSeek-V3.2 (671B MoE) improving task completion by +9.5 percentage points. Weaker models perform best with curated retrieval, with gpt-oss-120b (117B MoE) improving by +16.1pp while adding only +5% tokens. This method requires no weight updates or manual annotation; it works by distilling guides from an agent’s past trajectories and injecting them at inference time.
