Tree-Memory architecture
A memory that reads the past in logarithmic time. Instead of rereading everything on every token, the model walks a hierarchical tree and opens only the branches that can change the answer — with the same answers as full attention.
- Reads grow like log n, with no fixed context window
- Certified exact recall — identical to full attention in every test
- Learns new facts during use, without retraining
