Where it fits
GPT-4 Turbo 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 GPT-4 Turbo raw
Raw model intelligence matters less in production than retrieval, grounding and workflow orchestration.
Hallucinates wrong answers. It confidently gives incorrect details about your product or policies.
Stale answers. It repeats outdated info even after your guides or policies change.
No account context. It can’t access the customer’s order or account details to help.
Inconsistent retrieval. It misses key info in your docs or links to unrelated content.
Policy drift. It strays from your brand voice or rules over long chats.
No human handoff. It can’t escalate to a real person when needed.
The Chatref way
The model is one layer. Grounding is the rest.
The model is one layer – grounding, retrieval, and escalation decide production success.
