  TruEra was an AI quality, observability, and governance platform that was acquired by Snowflake in
  May 2024. The standalone TruEra product is being absorbed into Snowflake's Cortex/AI platform. The
  open-source TruLens evaluation library (originally from TruEra) remains active as a standalone
  Python project for LLM and RAG evaluation.

      TruEra's hosted AI quality platform offered REST APIs for ingesting models, predictions, and
