Multi-tier semantic cache
Why it wins
Compared with no-cache or string-only reuse, TokensChain layers semantic matching on top of multi-tier storage.
How it works
- Semantic match — recognizes intent-equivalent requests via embeddings, not string comparison.
- Three tiers — in-memory, on-disk and clustered, balancing latency with capacity.
- On high-frequency Q&A and scripted flows, hit rate can reach roughly 45%, reducing duplicated compute.
