# Sparse Steerable Retrieval — BatchTopK SAEs

BatchTopK SAEs trained on MuQ-MuLan music4all audio embeddings (512-d), one per sparsity level L0. Each `L0-*/` holds `last.ckpt` (encoder/decoder weights) + `config.yaml`. Load via `steerable_retrieval.steer.load_steerable_sae(repo, subfolder='L0-20')`.
