LLM extraction retries must use stable keys to prevent duplicate healthtech records

This article discusses how to handle retries and prevent duplicate records in healthtech data extraction pipelines that use LLMs. It emphasizes the importance of using stable document hashes or external record IDs as unique keys to ensure idempotency. The author suggests a state machine approach where submissions are made once, and then polled for completion, with database writes being upserts keyed by the source document. This method aims to maintain data quality and prevent duplicate patient-facing records, even when dealing with webhook delivery failures or model inference issues. AI
