What is MLflow?
MLflow is an open‑source AI engineering platform that supports agents, large language models (LLMs), and traditional machine learning models. It provides end‑to‑end observability by capturing full traces of LLM and agent execution using OpenTelemetry, enabling users to monitor performance, cost, and safety in production.
MLflow offers systematic evaluation tools that track quality metrics over time, allowing teams to detect regressions and improve model reliability. The platform includes a prompt registry with versioning, lineage tracking, and automated prompt optimization, helping developers manage and refine prompts efficiently.
An AI Gateway offers a unified OpenAI‑compatible interface to route requests, control rate limits, and manage fallbacks across multiple LLM providers. For model development, MLflow supports experiment tracking, hyperparameter tuning, model evaluation, and a production model registry for deployment.
It integrates natively with over 100 AI tools and languages such as Python, Java, TypeScript/JavaScript, and R, and can run in any cloud or on-premises environment. MLflow’s Agent Server delivers FastAPI‑based hosting for agents, simplifying the transition from prototype to production endpoints.
