How much of the past do we read?

Each numbered tile is a token position. Move the query earlier: later positions must become unavailable in every mode.

Solid border: read. Dashed border: not read (outside the local window or not selected). Crossed out: future. A joined tile represents one compressed entry.

16context entries retained

16entries read by this query

What this small model leaves out

In the compression modes, each pair becomes one placeholder for a learned summary vector. We do not compute that vector. The supplied shortlist selects the group containing position 3 and the newest distinct group. A real indexer must find useful groups from data, which costs computation and can miss useful information.

These counts describe one query’s context entries. They exclude index scoring, projections, local branches, vector widths, caching overhead, and all other layers. They are neither total FLOPs nor predicted speedups for DeepSeek.
