Or, you can set your JinaAI API key in the config.yaml file directly.

- module_type: jina_reranker
  api_key: your_jina_api_key

batch : The size of a batch. It sends the batch size of passages to jina API at once. If it is too large, it can cause some error. (default: 8) You can increase when you have higher ‘rpm’ and ‘tpm’ limit from Jina AI.
model : The type of model you want to use for reranking. Default is “jina-reranker-v1-base-en” and you can change it to “jina-reranker-v1-base-en” or “jina-colbert-v1-en”
api_key : The cohere api key.

- module_type: jina_reranker
  api_key: your_jina_api_key
  batch: 16
  model: jina-colbert-v1-en
