Published at ICLR 2025.\nPaper: \"Benchmarking Chat Assistants on Long-Term Interactive Memory.\"\n\nVolt's LCM (Lossless Context Management) is specifically designed to preserve and\nretrieve context across long conversations — summaries, large file storage,\nconversation ancestry. This benchmark is a natural fit for measuring how well\nLCM actually performs at long-term recall.\n\n## Required work\n\n1. Read the LongMemEval repo and understand the evaluation protocol, task categories,\n   and metrics.\n2. Determine what adapter/harness is needed to run Volt against the benchmark.\n3. Implement the adapter.\n4. Run the eval and report results.\n\n## Open questions\n\n- What conversation lengths does the benchmark test? Does it exceed Volt's\n  compaction thresholds?\n- Does the benchmark require multi-session memory or single-session only?\n- What are baseline scores for comparable systems?\n\n## Reference\n\n- Repo: https://github.com/xiaowu0162/LongMemEval\n- Paper venue: ICLR 2025","priority":"4","title":"Run LongMemEval benchmark against Volt's LCM","type":"task"}}
