By a knowledgeable/skilled person who listens to the call. (Which the AI solution provides).

Can you point me to the information you evidently have about which models Kaiser is using? All I can find is that they're using innovaccer, which can use any of anthropic, openai, and meta models on AWS or azure. Even their published papers don't seem to specify a particular model or capability level, just "AI". For all we know it's a gpt mini or similarly cost-effective model that has the context awareness of a Labrador hearing the word "walk".
