DeltaStore + TSC

Persistent state, replayable memory, and temporal compression for enterprise AI systems.

DeltaStore is the temporal memory fabric: store changes instead of full state, reconstruct any prior point, and make system history auditable by default. TSC is the model-memory codec layer inside that stack, with strong offline KV compression results and an emerging live-cache frontier.

The approach

Systems Over Models

Architecture makes lightweight models perform like frontier ones. Tool orchestration, structured reasoning, and persistent memory — no fine-tuning, no expensive inference.

The model is a component. The system is the product.
