Where it fits
Nova Pro across support workflows
How well the model suits each job – grounded in what it can really do, not hype.
Why this matters
What breaks when you run Nova Pro raw
But in production, how the AI retrieves answers from your content and hands off to humans matters more than raw intelligence.
Wrong answers. It confidently makes up details your product doesn’t have.
Stale info. It can’t update answers when policies or features change.
No context. It doesn’t see the customer’s account or order details.
Inconsistent. It gives different answers to the same question.
Off-topic. It drifts from your brand voice in long chats.
No handoff. It can’t pass the chat to a human when needed.
The Chatref way
The model is one layer. Grounding is the rest.
The AI is just one layer – grounding, retrieval, and escalation decide if it works for your business.
