ej

ej is an 11 MB decision model that answers routing and triage questions about text with probabilities on CPU.

ej is a small decision model designed for routing, triage, yes/no checks, and priority questions about text. It runs entirely on CPU from a single 11.4 MB file, working offline without any external API or GPU requirement. The software uses open weights and Apache-2.0 licensed code, distributed via pip install ejai. Users describe a decision, provide records, and receive a probability score for every option to set thresholds for automation. It suits teams making repetitive text decisions who want local execution and probabilities instead of unstructured text generation.
