Backend preset for a local TEI server serving the merged SPECTER2 proximity model — backend_specter2

Convenience wrapper around backend_config() for a SPECTER2 setup served by a local TEI (text-embeddings-inference) server. The model itself must be prepared and started externally (see inst/scripts/prepare_specter2_merged.py and inst/scripts/start_tei_specter2.sh, and the specter2-setup vignette).

Usage

backend_specter2_tei(
  port = 8080L,
  host = "localhost",
  model = "allenai/specter2_proximity_merged"
)

Arguments

port: Port that TEI is listening on. Defaults to 8080.
host: Host for TEI. Defaults to "localhost".
model: Provenance label for the served model. Defaults to "allenai/specter2_proximity_merged".

Value

A backend configuration list compatible with backend_config().

Details

The model argument is metadata only and is recorded in embed_model.yaml and parquet partition paths; TEI itself loads whichever model it was started with.
