Guild AI
Guild AI is an experiment tracking tool for machine learning projects.
What Guild AI is
Guild AI is an experiment tracking tool for machine learning projects. It can run unmodified training scripts and save each run as a distinct experiment, recording details such as flags, results, metadata, and source snapshots. Its batch operations support grid search, random search, and sequential Bayesian optimization. Guild View is a browser-based interface for browsing runs, files, and metadata and comparing results; Guild Compare presents runs in spreadsheet form and can export data as CSV. Guild also integrates with TensorBoard and supports TensorFlow and Keras. Remote operation and synchronization are available for several listed systems, including SSH, EC2, S3, Azure VM, Azure Blob Storage, and GitHub Gists, with capabilities varying by type. It can operate without a database or external system and is open source. Installation options documented include pip, conda, Docker, and source code. Precompiled packages are listed for Linux, macOS 10.14 and 10.15, and Windows 10.
Good
- Tracks flags, results, metadata, and source snapshots
- Offers grid, random, and Bayesian optimization
- Compares runs and exports data as CSV
- Runs without databases or external systems
Watch out
- GitHub Gist runs are public by default
- Random search defaults to 20 trials
- Summary files outside a run directory are not shown
Who it suits
Guild AI suits machine-learning practitioners who want to track experiment runs, compare results, or search hyperparameters. It may also fit users who need TensorBoard integration or remote run workflows.
Verdict
Guild AI combines experiment records, parameter search, and run comparison in an open-source tool. Users should pay attention to Gist visibility and the documented limits on trial defaults and summary-file display.
