Databricks' managed foundation-model fine-tuning service, driven by the databricks_genai SDK, which customized a base model on your own data and registered the result to Unity Catalog.
- It reached end of life while still officially in Public Preview - the Azure copy of its own docs carries a Public Preview region list directly beneath the end-of-life warning.
- The whole service was a Python import away, and the thing that no longer works is precisely that import - the databricks_genai package and its UI both went dark together.
- It outlived several of the models it existed to tune, retiring DBRX, Mistral and Mixtral from its own supported list in April 2025.
Limitations: While it ran, datasets beyond roughly 10B tokens were unsupported, continued pre-training expected 60-256MB files with anything over 1GB slowing sharply, and older base models could be dropped from the API without notice.
