Qwen Rerank
The reranking tier of the Qwen family selects the genuinely pertinent passages from the candidates of a file search before the language model gets to see them, and stays small enough to run alongside language model and embedding on the same graphics card. Under professional-secrecy law the route decides: in dedicated operation on reserved hardware in a German data centre the chain is closed - open weights, no model vendor anything is transmitted to, and the data centre operator bound via the chain obligation under section 203(4) of the German Criminal Code. Via IONOS, by contrast, the product-specific confirmation of the section 203 clause is still outstanding, even though the reranking has file extracts before it in plain text.
Everything section 203 requires is settled, including the provider's confidentiality undertaking. You do not have to clarify anything further.
What it is good for
- Lifts the hit quality of a file search clearly above pure embedding search
- 0.6 billion parameters in BF16, around 4 GB - fits alongside generator and embedding on one card
- Apache 2.0, available from German data centres or on the dedicated instance
Where it stops
- A side role in the search pipeline - without embedding and a language model it has no function
- It is given file extracts in plain text; contractually it has to be treated like a language model
- The product-specific confirmation of the section 203 clause for the AI Model Hub is still outstanding
Routes examined
The same model, procured differently, is a different legal position. What is examined per route is the contract chain, not the model.
| Route | Section 203 status | Version on this route |
|---|---|---|
| Dedicated instance in Germany, operated by Gosign | covered | - |
| IONOS AI Model Hub (German data centres) | conditional | - |
The conditions behind a conditional status - which piece is open on which route and who closes it - are set out in the full matrix in the German catalogue, and we go through them in the conversation. The German page for Qwen Rerank carries the sources with their retrieval dates.
