How to Switch AI Models Without Rebuilding Your App

Switching AI models on the platform is a configuration change, not a code change. Your chatbot, workflow, or custom app keeps working exactly the same way, just with a different model generating the responses. You can switch in seconds from the admin panel and the change takes effect immediately for new conversations.

How Model Switching Works

The platform abstracts the AI model behind a standard interface. Your chatbot's system prompt, knowledge base, conversation format, and all other settings remain unchanged when you switch models. The only thing that changes is which model processes the request and generates the response. This means you can freely experiment with different models without any risk to your existing setup.

Switching a Chatbot's Model

Step 1: Go to your chatbot settings.
Open the AI Chatbot app in the admin panel and select the chatbot you want to modify.

Step 2: Change the model selection.
Find the AI model field and select a different model from the dropdown. Choose from GPT-4.1-mini, GPT-4.1-nano, Claude Sonnet, Claude Opus, GPT o3-mini, or any other available model.

Step 3: Save and test.
Save the chatbot configuration. The new model takes effect immediately for all new conversations. Existing conversations in progress will use the new model for their next message. Send a few test questions to verify the output quality meets your expectations.

Switching Models in Workflows

In workflow automations and chain commands, each step can use a different model. Change the model for any individual step without affecting other steps. This lets you optimize one step at a time, testing each change independently.

Switching Models in Custom Apps

For custom apps, the model is specified in the app code. Use the AI builder to update the model parameter in your app's AI function calls. If your app uses multiple AI calls, you can change each one independently.

What to Watch For When Switching

System Prompt Compatibility

Different models interpret system prompts slightly differently. A system prompt that works perfectly with GPT-4.1-mini might need minor adjustments for Claude Sonnet, especially for formatting instructions or specific behavioral rules. After switching, test your most important use cases and adjust the system prompt if needed.

Response Length Changes

Models have different default verbosity. Claude tends to write longer, more detailed responses. GPT-4.1-mini tends to be more concise. If response length matters for your use case (SMS character limits, chatbot widget display), test the new model and add length constraints to your system prompt if needed.

Cost Changes

Different models have different per-request costs. Switching from GPT-4.1-mini to Claude Opus increases costs significantly. Switching from Claude Opus to GPT-4.1-mini saves money but might reduce quality. Check the pricing comparison before switching and monitor your credit usage after.

Active Conversations

When you switch a chatbot's model, existing conversations continue with the new model. The model switch is transparent to the customer. However, if the new model has a noticeably different personality or writing style, customers in active conversations might notice a change in tone. For critical applications, consider timing model switches during low-traffic periods.

Rollback

If the new model is not working well, switch back to the previous model. The change is instant and requires no downtime. Nothing is lost when you switch models. Your knowledge base, conversation history, and all settings remain intact.

Try different models risk-free. Switch in seconds and see the results immediately.
