Recommended action: Pass an explicit current rerank model name (see Cohere rerank docs) and either no client (API key from COHERE_API_KEY) or cohere.ClientV2(...); tune max_tokens_per_doc if long chunks are silently truncated. Option: Specify model and use ClientV2 [evidence: official_recommended_action] Applies when: langchain-cohere current Steps: 1. CohereRerank(model='<current rerank model>', top_n=5) 2. If passing a client: client=cohere.ClientV2(api_key=...) Expected: Reranker initializes Evidence basis (self-declared by the contributing chat client): untested.
