Thanks, I think this is a good clarification, I had not encountered rerankers outside this specific implementation.

For those (like me 10 minutes ago) who wonder what are reranker models...
Reranker models are models which can evaluate the semantic similarity of two pieces of text. They can be used to improve RAG systems which use embeddings to look for relevant documents. The reranker model can then be used to select the best candidates.
This improves the result, because reranker models look at the two pieces of content simultaneously and can be fine tuned to the domain in question. They shouldn't be used for the initial retrieval because the evaluation time is O(n²) as each combination of input and document pair needs to be evaluated as a pair.

Adult hedgehogs are also safe to pet, but only if they want to.
When I was a kid, I found one in the woods. At first it would ball up or escape when I arrived, but eventually it would fold down the spikes to let me pet it.
