We are excited to announce the release of MLflow 2.20.0! This release includes a number of significant features, enhancements, and bug fixes.

Major New Features

• 💡Type Hint-Based Model Signature: Define your model's signature in the most Pythonic way. MLflow now supports defining a model signature based on the type hints in your PythonModel's predict function, and validating input data payloads against it. (#​14182, #​14168, #​14130, #​14100, #​14099, @​serena-ruan)

• 🧠 Bedrock / Groq Tracing Support: MLflow Tracing now offers a one-line auto-tracing experience for Amazon Bedrock and Groq LLMs. Track LLM invocation within your model by simply adding mlflow.bedrock.tracing or mlflow.groq.tracing call to the code. (#​14018, @​B-Step62, #​14006, @​anumita0203)

• 🗒️ Inline Trace Rendering in Jupyter Notebook: MLflow now supports rendering a trace UI within the notebook where you are running models. This eliminates the need to frequently switch between the notebook and browser, creating a seamless local model debugging experience. (#​13955, @​daniellok-db)

• ⚡️Faster Model Validation with uv Package Manager: MLflow has adopted uv, a new Rust-based, super-fast Python package manager. This release adds support for the new package manager in the mlflow.models.predict API, enabling faster model environment validation. Stay tuned for more updates! (#​13824, @​serena-ruan)

• 🖥️ New Chat Panel in Trace UI: THe MLflow Trace UI now shows a unified chat panel for LLM invocations. The update allows you to view chat messages and function calls in a rich and consistent UI across LLM providers, as well as inspect the raw input and output payloads. (#​14211, @​TomuHirata)

Other Features:

• Introduced ChatAgent base class for defining custom python agent (#​13797, @​bbqiu)
• Supported Tool Calling in DSPy Tracing (#​14196, @​B-Step62)
• Applied timeout override to within-request local scoring server for Spark UDF inference (#​14202, @​BenWilson2)
• Supported dictionary type for inference params (#​14091, @​serena-ruan)
• Make context parameter optional for calling PythonModel instance (#​14059, @​serena-ruan)
• Set default task for ChatModel (#​14068, @​stevenchen-db)

Bug fixes:

• [Tracking] Fix filename encoding issue in log_image (#​14281, @​TomeHirata)
• [Models] Fix the faithfulness metric for custom override parameters supplied to the callable metric implementation (#​14220, @​BenWilson2)
• [Artifacts] Update presigned URL list_artifacts to return an empty list instead of an exception (#​14203, @​arpitjasa-db)
• [Tracking] Fix rename permission model registry (#​14139, @​MohamedKHALILRouissi)
• [Tracking] Fix hard-dependency to langchain package in autologging (#​14125, @​B-Step62)
• [Tracking] Fix constraint name for MSSQL in migration 0584bdc (#​14146, @​daniellok-db)
• [Scoring] Fix uninitialized loaded_model variable (#​14109, @​yang-chengg)
• [Model Registry] Return empty array when DatabricksSDKModelsArtifactRepository.list_artifacts is called on a file (#​14027, @​shichengzhou-db)

Documentation updates:

• [Docs] Add a quick guide for how to host MLflow on various platforms (#​14289, @​B-Step62)
• [Docs] Improve documentation for 'artifact_uri' in 'download_artifacts' (#​14225, @​vinayakkgarg)
• [Docs] Add a page for search_traces (#​14033, @​TomeHirata)
