model_card:
  best_for:
  - Fast first-pass grouping of text notes, captions, and metadata.
  - Semantic search over medium and large text projects on laptops.
  - A compact starter model for EIDORA text embedding workflows.
  not_ideal_for:
  - Long-document reasoning or generation.
  - Fine-grained domain retrieval where a larger text embedding model is acceptable.
  - Image, video, or audio inputs.
  limitations: E5 embeddings can reflect the biases and language coverage of the upstream
    training data. The upstream recipe recommends query and passage prefixes; quality
    may drop if text is passed without the expected prefix style.
