Run Real A/B Tests on Agent Memory Strategies — Not Vibes Comparisons

You want to know if reflection memory is paying off, if longer retention helps, if a different retrieval strategy outperforms. Without controlled experiments, every decision is vibes. MemoryLake provides branched memory for A/B testing — same users, different memory strategies, measurable outcomes.

The problem: agent memory decisions usually have no evidence

Should you increase retention? Switch retrieval ranking? Add reflection memory? Most teams ship the change to all users and hope for the best. No control group means no real measurement.

How MemoryLake enables memory A/B tests

Branched memory per cohort

Branched memory per cohort

Cohort A uses strategy 1; Cohort B uses strategy 2; same users otherwise.

MEMORYPer-cohort retrieval rules

Per-cohort retrieval rules

Different memory types, retention, or ranking per cohort.

MEMORYOutcome attribution via memory diff

Outcome attribution via memory diff

Measure what changed between cohorts.

How it works for memory A/B testing

  1. Connect — Define cohorts in the workspace.
  2. Structure — Each cohort uses a memory branch with different rules.
  3. Reuse — Measure agent outcomes per cohort; merge winning branch.
