What bm25 is

Usage Note: This model is supposed to be used with Qdrant. Vectors have to be configured with Modifier.IDF. Here's an example of BM25 with FastEmbed.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys bm25 for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (bm25 below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"bm25","input":"text to embed"}'
