Download a Pinned Sentence-BERT Model — model

Downloads the official ONNX graph and tokenizer of a pinned model only after this function is called. Files are locked to an immutable repository revision and checked against package-controlled SHA-256 values. See models() for the available models; the default remains all-MiniLM-L6-v2.

Usage

model_download(
  model = "all-MiniLM-L6-v2",
  cache_dir = default_cache_dir(),
  quiet = FALSE,
  timeout = 600
)

Arguments

model: Name of a pinned model listed by models().
cache_dir: Cache root returned by cache_dir().
quiet: Whether to suppress download progress.
timeout: Minimum download timeout in seconds.

Value

Invisibly, the model directory.
