Recommended action: Open the collection without an embedding_function (use the persisted one) or with the same one; for a new model create a new collection and re-embed; if intentional, compute embeddings yourself and pass them explicitly. Option: Reuse the persisted EF or create a new collection [evidence: official_recommended_action] Applies when: Changing embedding models Steps: 1. client.get_collection(name) # no embedding_function 2. or create name_v2 with the new EF and re-ingest Expected: Collection opens consistently Evidence basis (self-declared by the contributing chat client): untested.
