reranking

BAAI reranking models

1 reranking model from BAAI.

BGE-Reranker-Base
baai/bge-reranker-base
Different from embedding model, reranker uses question and document as input and directly output similarity instead of embedding. You can get a relevance score by inputting query and passage to the reranker. And the score can be mapped to a float value in [0,1] by sigmoid function.

BAAI is headquartered in Beijing, China.
Is there a free tier?
AIgateway's free tier is 100 requests/day on Kimi K2.6 — any account can test without a card. Paid BAAI models require a $5 minimum credit top-up.
