Currently, Cohere is available and can be configured, but you need to install llama-index-postprocessor-colbert-rerank first.

engine = SimpleEngine.from_docs(input_files=input_files, ranker_configs=[CohereRerankConfig(api_key="YOUR_API_KEY")])

Others can also be customized, such as voyage.

from llama_index.postprocessor.voyageai_rerank import VoyageAIRerank

engine = SimpleEngine.from_docs(input_files=input_files)
engine._node_postprocessors = [VoyageAIRerank(api_key="YOUR_API_KEY")]
