ML model configuration.

Fields

embedding_model: String

Embedding model name (default: “all-MiniLM-L6-v2”).

ner_model: String

NER model name (default: “gliner-multi-v2.1”).

llm_model: String

LLM model for relation extraction (default: “Qwen3-4B-GGUF”).

llm_backend: String

LLM backend: “candle” or “llama_cpp” (default: “candle”).

clip_model: String

CLIP model name for image embedding (default: “clip-vit-base-patch32”).

models_dir: String

Directory for storing model files.

enable_ocr: bool

Enable document OCR pipeline (default: true).

ocr_language: String

Language for Tesseract OCR (default: “eng”).

tesseract_path: String

Path to the tesseract binary (default: “tesseract”, relies on PATH).

fine_tuned_re_model: String

Fine-tuned relation extraction model name on Fireworks (e.g., “accounts/ucotron/models/re-qwen2-5-7b”). When set and non-empty, the extraction pipeline will use this model via Fireworks API instead of co-occurrence. Falls back to co-occurrence on API errors.

fine_tuned_re_endpoint: String

Fireworks inference API endpoint (default: “https://api.fireworks.ai/inference/v1”).

fine_tuned_re_api_key_env: String

Name of the environment variable holding the Fireworks API key (default: “FIREWORKS_API_KEY”). The actual key is read from this env var at runtime — never stored in config files.
