Amazon Rerank
The second stage of hit selection: from the candidates of the embedding search this model scores every passage against the question asked and sorts the genuinely pertinent ones to the top - without a search before it and a language model after it no usable result emerges. Via Amazon Bedrock the call runs region-bound in Frankfurt, without operator access and without storage in the delivered state. The chain is not closed by that: no signable standard document for the confidentiality undertaking under section 203 of the German Criminal Code could be found for this route. That weighs heavily, because the reordering has file extracts in plain text before it, not anonymous reference numbers.
You can work with it - but part of the safeguard is open: either the provider does not commit to confidentiality itself, or it depends on an agreement you still have to conclude. Which of the two applies to which route is set out in the full matrix.
What it is good for
- Evidenced region-bound in Frankfurt - processing in Germany without an inference profile
- Lifts the hit quality of a file search noticeably above pure embedding search
- No operator access and no storage in the delivered state
Where it stops
- A side role in the search pipeline - without embedding and a language model it has no function
- Sees file extracts in plain text and therefore has to be treated contractually like a language model
- A US group remains in the chain, even with processing in Germany
Status through us
The same model, procured differently, is a different legal position. The status above refers to procurement through us; processing takes place in a third country.
Which route carries it, with which instrument and under which condition, we set out in full to the firm before it commissions us - section 203(4) requires that the chain can be checked, not that it is published. The full matrix, with the sources behind every route, can be requested in the German catalogue after confirming your e-mail address, and we go through it in the conversation.
