LUML Flow

Purpose: Flow is a live experiment tracker for predictive machine learning and generative AI.
Tracking: It captures training parameters, step metrics, model artifacts, generative AI traces, evaluation samples, and human annotations.
Local use: Flow runs locally with a dashboard launched by `lumlflow ui` that reads a local SQLite store.
Account requirement: Flow can be used indefinitely without signing up; a LUML account is needed to upload experiments to a shared workspace.
Data handling: The page says there is no account or telemetry required for local use and experiments remain in the local SQLite store until uploaded.
Integrations: The page lists PyTorch, LangGraph, XGBoost, scikit-learn, LlamaIndex, TensorFlow, Anthropic, LightGBM, DSPy, JAX, LangChain, and Keras.
LLM tracing: Flow routes OpenTelemetry spans into experiment storage and describes instrumentors for OpenAI clients, LangChain, and LangGraph.
Storage and upload: Experiments are stored locally in SQLite, and uploaded models and experiment context become versioned artifacts in the LUML registry.
Open source: The Flow SDK and UI are in LUML’s public GitHub repository.
Intended users: The page presents Flow for people tracking predictive ML training and generative AI experiments, including teams that want to share runs through LUML.
Maker identity: LUML’s legal notice identifies the company as DataForce Solutions GmbH, headquartered in Linz, Austria.
Support: The LUML pricing page lists community support for its free Light plan and standard support for its paid Plus and Pro plans.
Experiment logging: Flow logs parameters, step metrics, model artifacts, traces, evaluation samples, and human annotations.
Local storage: The local dashboard reads experiment data from a SQLite store on your machine.
