  summary: "Lightweight open text embedder for A/B with BGE-M3 and long-context retrieval experiments."
  original_source: https://huggingface.co/nomic-ai/nomic-embed-text-v1.5
  use_cases:
    - "Secondary / A/B embedding path vs BGE-M3"
    - "English-heavy RAG with low resource cost"
    - "Long-context embedding experiments (per card capabilities)"
    - "Portable laptop offline search indexes"
  sweet_spots:
    - "Small footprint Apache embed"
    - "Fast iteration when re-embedding corpora often"
    - "Nomic tooling and Matryoshka-style dimension flexibility (per card)"
  not_ideal_for:
    - "Sole multilingual production embed without A/B (prefer BGE-M3 default)"
    - "Generation tasks"
    - "Code-only retrieval (prefer code embed if held)"
  capability_notes: >
    Compact Nomic text embedding model. Held as runnable dual-path to avoid
    single-vendor embed lock-in and to re-eval retrieval quality cheaply.
    Prefer current v2 text card at pull if clearly better.
swot:
  strengths:
    - "Tiny, Apache-2.0, easy to re-run indexes"
    - "Diversifies embed dependency next to BGE-M3"
  weaknesses:
    - "May lose multilingual or domain A/B vs BGE-M3"
    - "Version churn (v1.5 vs v2) needs careful pin"
  opportunities:
    - "Dimension-reduced storage for large corpora"
    - "Hybrid ensembles (BGE + nomic signals)"
  threats:
    - "Becomes redundant if one embed wins all lab evals"
    - "Upstream rename/deprecation of v1.5"
