Serve a registered MLflow model locally as a REST API with mlflow models serve
domain: mlflow.org · 5 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Reference the model with a URI such as models:/<name>/<version>, models:/<name>@<alias>, or runs:/<run_id>/model
Run mlflow models serve -m <model-uri> -p <port> --env-manager local|virtualenv|conda to start a FastAPI/uvicorn server
Optionally pass --enable-mlserver to serve via MLServer instead of the default server (requires the mlserver extras)
POST inference requests to the /invocations endpoint with a JSON body using the dataframe_split or instances/inputs keys
Check server health via /ping or /health, and confirm the served model version via /version
Known gotchas
Avoid the dataframe_records payload format; MLflow's docs warn it can silently reorder columns
--env-manager virtualenv/conda rebuilds the model's captured environment and can be slow on first run; local reuses your current environment but skips dependency isolation
Without a logged model signature, JSON payloads lose type information and can cause type mismatches at inference time
