Amos 1 MediumFreescira/amos-1-medium · Free ($0). 9B, 128K context. Fast and accurate.
Amos 1 SmallFreescira/amos-1-small · Free ($0). 2B, 256K context. Sleeps when idle; first call can take ~2 min.
Amos 1 MiniFreescira/amos-1-mini · Free ($0). 0.5B encoder, 9K context. The fastest.

Amos 1 is a family of open-weight (Apache 2.0) decision models from Scira. They write no text: send state and typed questions (noul / choice / score) to POST /api/v1/decisions and get a probability for each answer in one pass. Large leads Decision Bench at 94.9%.

All four are **free**: no BYOK key needed, $0 per request. English only. Amos keeps every request to train future models, so do not send data you may not share. Because of that, **Always enforce ZDR** (Dashboard → Privacy) excludes them: with it on, the API answers 403 zdr_required; with it off (the default) they route normally, signed out too.
