# Models

The models mivia ships: small single-purpose artifacts behind strict
JSON APIs. One model ships today.

## mivia-small-json

Any text in, strictly valid JSON out. Give it a raw string - a log
dump, a ticket in German, a chat message - plus an output schema, and
it returns a complete, valid record or a typed clarification, never a
refusal and never invalid JSON.

- Twelve built-in schema classes plus your own, selected zero-shot
- Nine languages served end to end
- ~650 MB of int8 artifacts, CPU only, under 2 GB of RAM
- REST API and MCP server in one non-root container
- No request logs, no retention: nothing you send is kept
