Summary

MLflow 3.9.0rc0 is a pre-release introducing significant GenAI features like the MLflow Assistant, Trace Overview Dashboard, integrated AI Gateway, and LLM Judge capabilities.

Migration Steps

  1. To use the new AI Gateway features, note that the server is now located directly in the tracking server process.

✨ New Features

  • Introduction of MLflow Assistant, an in-product chatbot backed by Claude Code to help diagnose and fix issues in the MLflow UI.
  • New Trace Overview Dashboard in GenAI experiments providing pre-built statistics like latency, request count, quality metrics, and tool call summaries.
  • Revamped AI Gateway feature: the Gateway server is now integrated directly into the tracking server, eliminating the need for a separate process. Includes passthrough endpoints, traffic splits, and fallback models.
  • Support for Online Monitoring with LLM Judges, allowing automatic evaluation of traces using pre-defined or custom judges without writing code.
  • New Judge Builder UI within the GenAI Experiment UI to define, iterate, and test custom LLM judge prompts.
  • Implementation of Distributed Tracing, enabling context propagation across different services and processes for end-to-end request lifecycle tracking.
  • Introduction of MemAlignOptimizer, a new judge optimization algorithm that learns from past feedback and retrieves relevant examples for more accurate evaluations.
