Buyers also underestimate how labeling discipline affects custom models. Amazon Comprehend and Expert.ai Platform both require labeling guidelines and evaluation loops, while Luminoso and Kapiche depend on consistent dataset curation discipline across repeated runs.

  • Assuming structured outputs will be usable without offset and confidence metadata

    If indexing and span alignment are required, validate that outputs include offsets and confidence metadata in the payload. Google Cloud Natural Language AI is built around structured JSON with offsets and confidence metadata for direct downstream indexing.

  • Choosing custom training without a plan for labeling, evaluation cycles, and governance

    Amazon Comprehend custom models demand labeling discipline and evaluation cycles, which can slow releases if annotation capacity is not planned. Expert.ai Platform requires careful annotation guidelines and evaluation loops to support advanced tuning.

  • Expecting advanced relation extraction to work as a turnkey workflow

    Amazon Comprehend can require custom orchestration for some advanced relationship tasks, which means extra workflow components may be needed beyond the managed endpoints.
