AFM-D decision models - Aria Compute

AFM-D is Aria Compute’s dual-track System 1 decision product. Both tracks take a text or JSON state plus typed questions and return a distribution over the answers you supply. They do not run autoregressive chat.

Track	Model id	Architecture
Encoder	`afm-de`	Non-autoregressive ModernBERT + MASK option head
Decoder	`afm-dd`	SemIf direct option-letter logits on MiniCPM5-2B (optional LoRA)

Typed primitives

Primitive	Answer space
Choice	1–255 options (Decoder System One typically 2–16)
Score	2–10 ordered levels
Noul	`false` / `true`

Hubs

Hub	Encoder	Decoder
Hugging Face	`ariacompute/afm-de`	`ariacompute/afm-dd`
ModelScope	`AriaCompute/afm-de`	`AriaCompute/afm-dd`

How to run

Aria Engine — official System One HTTP (POST /v1/systemone); default binds encoder :8010, decoder :8011.
Ollaya — local decision-model daemon; ollaya pull afm-de / afm-dd.
ROUTER afm-d layer — gold entrypoint ariacompute/afm-d-auto (needs engine at AFM_ENGINE_URL).
