THEN Set chunk_size to a value such that each text chunk does not exceed 2048 characters. For Cohere models via Bedrock, the limit is character-based, not token-based. A chunk_size of 80 with overlap 10 works, but for larger chunks, implement a custom text splitter that enforces a 2048-character limit.
