An open source AI engineering platform built for teams developing agents, LLMs, and machine learning models, providing experiment tracking, LLM evaluation with 50 plus built-in metrics, trace-based observability built on OpenTelemetry, a production model registry, and prompt optimization tools.
Expert Video Review by SEOGANT · March 2026
MLflow is the largest open source AI engineering platform for developing, evaluating, and deploying agents, large language models, and machine learning models.
Originally created by Databricks in 2018 as an experiment tracking tool for machine learning, MLflow has expanded into a comprehensive AI engineering platform covering the full lifecycle from development through production monitoring.
The platform is free, open source, and backed by Databricks, with a community of contributors across the AI and ML ecosystem.
The platform's LLM and agent capabilities address the observability and evaluation challenges that teams face when building production AI applications.
MLflow captures complete traces of LLM applications and agent workflows using OpenTelemetry standards, providing deep visibility into how AI systems behave across complex multi-step interactions.
The tracing capability is built on the OpenTelemetry GenAI semantic convention, ensuring compatibility with the broader observability ecosystem.
MLflow includes over 50 built-in evaluation metrics and LLM judges for assessing model quality, with the option to define custom metrics for domain-specific evaluation criteria.
The evaluation framework allows teams to systematically compare model versions, prompt variations, and configuration changes against measurable quality criteria rather than relying on manual review.
