Ars Notoria, an open-weight fiction lab with a ledger

Field notes

The project says its corpus begins with thousands of roleplay turns, then removes identifying details and manually rewrites promising scenes before training. Its hardware strategy is unusually concrete: it rents GPUs by the hour, tests on the same card, and returns it. Vex is presented as a 14B model, while 24B The Rubric and 70B The Greater are marked sealed or forthcoming; the site also describes a ledger for donations, compute, and runs.
