Embedding model
The model that turns each passage into a vector for meaning-based search. Frozen after creation — vectors from two models are not comparable, so changing the model means a new knowledge base and a re-upload. The default comes from Models.
If the dropdown is empty and a No embedding model configured warning shows, the workspace has no usable embedding model — see Models.
Chunking method
How Ragenta splits a document into passages. General suits ordinary prose; the others are for FAQs, tables, legal text, books, papers… Pick from the table in Chunking methods. Can be overridden per file at upload.
Chunk size (tokens) and Overlap (%)
- Chunk size: 64–2048, default 512. Short chunks match more precisely but carry less context; long ones the reverse.
- Overlap: 0–50 %, default 15. The part shared by two neighbouring chunks so a sentence is not cut in half and lose its meaning.
The Q&A, Table, One and Presentation methods ignore both, because their unit is already given (a Q&A pair, a row, the whole file, a slide).
Indexing extras
| Option | Effect | Cost |
|---|---|---|
| Keywords per passage (0–10) | A model writes keywords for each passage, improving keyword search. | One extra model call per passage at indexing time. |
| Questions per passage (0–5) | A model writes the questions the passage answers. Useful when people ask in different words than the document uses. | Same. |
| Summary tree (RAPTOR) | Builds additional summary passages in layers, so a broad question can find an answer spanning the whole document. | Noticeable on long documents. |
All three are charged as ingestion credits. Leave them off to start.
