The system now automates 63% of documentation workflows, cut documentation time to under five minutes, freed up 1.5 developers, and is estimated to add 1 billion BRL in productivity.","company":"Orizon","industry":"Healthcare","country":"Brazil","aiCapabilities":["Large Language Models","Document Intelligence","Fraud & Anomaly Detection"],"technology":["Delta Lake","MLflow","Databricks Model Serving","Unity Catalog","Databricks SQL","Llama2-code","DBRX","Agent Bricks"],"deployment":"Public Cloud","problemStatement":"Orizon had around 40,000 medical rules with about 1,500 new rules added each month, each requiring a developer to look at legacy C#/C++ code, document it and create a flowchart, a manual and error-prone process that consumed considerable IT resources and created bottlenecks between business analysts and developers.","solutionApproach":"Orizon adopted a data lakehouse architecture on the Databricks Data + AI Platform with Delta Lake for reliable ACID data storage, used MLflow to manage the machine learning lifecycle, fine-tuned the Llama2-code and DBRX GenAI models with its own data and business rules, deployed them through Databricks Model Serving, embedded them into Microsoft Teams, and secured proprietary business rules with Unity Catalog's granular permissions.","businessValue":"Orizon now processes 63% of tasks automatically, documentation that used to take days now takes under five minutes, the change freed up one and a half developers for higher-value work, saved approximately $30K per month in better-used resources, and is projected to add 1 billion Brazilian reals in productivity by scaling new-rule creation from 1,500 to 40,000 per month.","evidence":{"band":"high"},"sourceUrl":"https://www.databricks.com/customers/orizon","dates":{"publishedAt":"2026-09-16T09:05:21.687Z","publishedAtSource":"pipeline","updatedAt":"2026-09-16T09:05:21.687Z"},"license":"Open for reading and citing with a link to https://findausecase.com/use-cases/orizon-fine-tunes-genai-models-on-databricks-to-automate-63-of-healthcare-fraud-detection-code-documentation.
