Configure Default Model Bindings

The Default Bindings tab selects the active default for Generator, Embedding, Reranker, Rewriter, Table Summary, Enrichment, and Parsing.

Each selector shows only enabled models registered for that slot. Choose the model that should handle future work in that role.

Change embedding safely

Embedding also has a dimension selector. Changing an existing embedding model or dimension opens Reindex Required because vectors made with incompatible settings cannot share the same active index.

Before confirming:

1. identify the affected Knowledge documents;
2. choose a maintenance window if retrieval coverage may change;
3. confirm the provider and model have been validated; and
4. monitor reindexing and test retrieval afterward.

Other binding changes affect subsequent operations but do not automatically repair content produced earlier. Rerun the relevant document stage when historical output must use the new model.
