Where it fits
Nova 2 Lite 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 2 Lite raw
Real-world support needs precise retrieval from your docs, not just raw model smarts.
Hallucinated answers. It confidently gives wrong details about your product or policies.
Stale information. It repeats outdated instructions even after your docs are updated.
No customer context. It can't see the user's account details to personalize help.
Inconsistent retrieval. It might miss key info in your docs or repeat the same answer.
Policy drift. It starts suggesting things your team wouldn't approve of after long chats.
No human handoff. It can't flag urgent issues or pass chats to your team.
The Chatref way
