This partial overview contains the full profiles from NOLO GmbH to Zweitag GmbH. You will find further suitable providers in the topic overview. The classification determines the position of the profile, not an exclusive specialisation.
Distinguish answer search from RAG
A maintained answer search finds approved entries and reproduces their wording. Retrieval-Augmented Generation, RAG for short, combines the search for suitable content with a language model that formulates an answer from it. For the selection it matters which of these scopes a provider actually describes.
RAG needs suitable search results and a controlled passing on of content. Technical integration alone does not yet decide whether the answer is usable for your specialist area. Check the result and its source location together.
