Empire325's take
Empire325 RAG pipelines for international clients (LATAM, EMEA) use Cohere for embeddings + rerank. The two-stage flow (embed → top-100 → rerank → top-10) consistently lifts retrieval quality 15-25% on client data vs vector-only retrieval. For monolingual English RAG, OpenAI embeddings + a separate cross-encoder reranker is also fine.
