d1a-client (Python)

A dependency-free client for D1A, a small decision model on Gemma 4, or any other server that speaks the System One API (POST /v1/systemone). The model itself, its trainer and server are in the D1A repository, which is built on Kev by Jared Palmer.

The default model name is d1a-latest, the only name a D1A server lists; it answers any model name a request sends.

pip install d1a-client

from d1a_client import Client

client = Client("http://127.0.0.1:8009")          # api_key="..." if the server sets D1A_API_KEY
answer = client.decide("Shoes arrived late and I was charged twice.",
                       {"team": {"type": "choice", "instructions": "Which team should handle this?",
                                 "criteria": {"returns": None, "shipping": None, "billing": None}}})
print(answer["answers"]["team"]["probabilities"])

client.decide(state, questions, use_case="routing") names the request's use case: a D1A checkpoint with a temperature for it (its use_case_temperatures in GET /v1/models) reads the answers at that temperature; otherwise the checkpoint's own applies. Without use_case the request is sent exactly as before.
