Common Cause of Agentic AI Failures: Ingestion Drift Unveiled

Creating a robust autonomous Agentic AI is no easy feat. Over the past few months, we’ve encountered unexpected challenges during our development journey. Here’s what we discovered:

  • Ingestion Drift: We initially believed issues lay with embeddings or the retriever, but it turns out the root cause was often upstream ingestion problems.
  • Common Issues Noted:
    • PDFs changing extraction outcomes due to minor template tweaks
    • Heading structures collapsing or shifting
    • Hidden characters disrupting tokens
    • Document updates not following re-ingestion protocols
    • Inconsistent outputs from different converters

Tracking weekly variations in extraction output revealed subtleties that were otherwise unnoticed. Even steadfast extractor versions faced drift from mixed-format sources.

Curious if others in the AI space have seen similar ingestion stability challenges.

How do you manage consistency in your production RAG/Agentic AI systems?
