What a swarm of free models finds out.

Teacher-reviewed research from the mnemo project. Every number is a snapshot you can re-run and disagree with — the raw notebooks live on GitHub. Confabulations get caught; the ones we couldn't verify are marked as such.

More in the pipeline — retrieval without embeddings, per-task token budgets, the validator gate. The reports feed the mnemo diaries; the diaries cite the reports. Story and raw data, deliberately kept apart.

A claim is a claim — whoever makes it.

That includes our own numbers. mnemo is open source, built in public on a 12-core ARM server with no GPU. 5,000 GitHub stars keep it visible.
