## About this market
Generative AI at program scale looks different from a single assistant. Netcompany's TopGPT for Topdanmark masks personal data on locally hosted models before a retrieval step reads the customer's own policy documents; it has been live around the clock since April 2024 and passed 80,000 conversations by that November. Babel's quality-monitoring platform for WiZink reviews 100 percent of customer interactions in Spain and Portugal and cut a campaign review from several days to hours (January 2026). Merantix Momentum's LLMoin text assistant came out of Hamburg's governed use-case portfolio, while its Federal Chancellery work ended as a proof of concept on a locally hosted Mixtral 8x7B. Vstorm's agents run inside products: Mixam's order advisor serves 10,000-plus daily users, and the Schmitt-Thompson clinical triage system scores 93 percent disposition accuracy across 591 nurse-validated scenarios, with the write-up naming what still fails.

The sorting question is how output is controlled once the system faces users. TopGPT's local masking, the Chancellery's locally hosted model, the syntax validator that rejects illegal code in Vstorm's Synera agent and the nurse-validated scenarios behind Schmitt-Thompson are documented control layers; ask each candidate for the equivalent in its own work. Then ask for usage a year in. Topdanmark and Mixam publish figures; Kruso's IKEA chatbot and Billund search do not, and the curator notes the model work in each sits with Microsoft Bot Framework and Raffle.ai. The curator notes Merantix Momentum's generative record is shorter than its machine-learning record; ask for one in production today with usage figures.
