+#### Reranking Endpoint (`plugins/reranking-endpoint/`)
+
+A FastAPI service that provides document reranking using cross-encoder models (BGE-reranker, Qwen3-Reranker, etc.) via Ollama.
+
+**⚠️ Limitation:** This is a workaround that uses embedding magnitudes instead of the proper classification head. Ollama doesn't expose the `/api/rerank` endpoint or classification layer that cross-encoder models are designed to use. Less accurate than sentence-transformers but integrated with Ollama's GPU scheduling. See [plugins/reranking-endpoint/README.md](plugins/reranking-endpoint/README.md) for detailed limitations.
