# Marlowe memory rerankers

> **Not intended for individual download.** These files are fetched automatically by the

Fine-tuned MS MARCO MiniLM cross-encoders (ONNX) that marlowe-cowork uses to rerank recalled memories.

| Folder | Use |
|---|---|
| `ms-marco-MiniLM-L-2-v2-ft-session-j` | the shipped reranker (CPU) |
| `ms-marco-MiniLM-L-6-v2-ft-session-j`, `ms-marco-MiniLM-L-{2,4,6,12}-v2-ft-w1` | the GPU rerank cascade (CUDA builds) |

Each folder holds `model.onnx` and the shared `tokenizer.json`. The embedder is the upstream
`jinaai/jina-embeddings-v2-small-en`.
