LCM: Deterministic Memory Architecture Outperforms Claude Code on Long-Context Tasks

arXiv·high signal

Lossless Context Management (LCM) shifts memory burden from the model to a deterministic engine using recursive context compression (hierarchical summary DAG) and recursive task partitioning (engine-managed parallel primitives). The LCM-augmented coding agent Volt scores higher than Claude Code on the OOLONG long-context eval at every context length from 32K to 1M tokens using Opus 4.6. Accepted at ICLR 2026.
