The official TypeSafe SDK can target this local server, but inference uses GLiFormer and its own probability and confidence calculations.

Getting started

Use Python 3.12 and uv, download the checkpoint, set JEFF_API_KEYS and point the client at localhost:8000.

Scope and limits

Choice and Score questions can affect one another unless isolation is enabled. Reported token counts are not comparable to Jev billing.
