Choosing the Right AI Model for Your Store's Chat Widget

Why bring-your-own-key matters

When you connect your own key, you pay the AI provider's actual rate for usage — not a markup baked into a subscription tier. It also means your conversation data flows through your own account under your own provider agreement, which matters if your store has specific data-handling requirements.

Picking a starting point

There isn't a single "best" model for every store — the right pick depends on what you're optimizing for.

• Starting out or want zero setup: use MerchantDesk's built-in default and switch later without losing any configuration
• Optimizing for nuanced, on-brand responses at a moderate catalog size: a Claude model is a strong default
• Running a very high message volume and watching per-conversation cost closely: a faster, lower-cost tier from any provider keeps margins predictable
• Already standardized on a provider elsewhere in your stack: use that same provider's key so billing and usage stay in one place

Switching is safe to experiment with

Because the model choice is just a connected key, not a structural decision, switching providers doesn't mean rebuilding your setup. Your catalog training, widget configuration, and conversation history all stay put — only which model answers changes. That makes it low-risk to test a different provider for a week and compare resolution quality before committing.
