01 — THE QUESTION

Do different agent memory systems actually change what an agent does?

world events→ memory system→ what memory surfaces→ LLM planner→ action→ did the right thing?
02 — THE FINDINGS

EIGHT CHALLENGES × FOUR MEMORY SYSTEMS × TEN IDENTICAL RUNS EACH

1

The long-memory cliff

0 / 10 VECTOR · 4 & 8 SESSIONS 10 / 10 MEM0 & LETTA

2

Having the fact ≠ using it

Watch a stale-memory failure ↓
3

Different memory systems break at different points

THE FULL MATRIX · DID THE RIGHT THING, OUT OF 10 IDENTICAL RUNS

03 — THE PROOF

MEMORY RACE · SAME WORLD, SAME SEED, SAME CHALLENGE

Four memory systems run the identical episode. When does behavior diverge?
