How to switch between models
You can change model used by your chatbot in by going to the Dashboard, then Settings and using the dropdown to choose a different AI model.
Changing models is possible only on our Hobby, Standard and Business plans.
How to use own OpenAI or OpenRouter API key
You can optionally use your own OpenAI or OpenRouter API key to bill your chatbot messages to. This helps with cost management.
If you provide your own API key, all messages will be sent using it (not our key). You’ll need to ensure that you have access to the chosen model and you’ll manage the API limits and billing yourself.
In other words: we are unable to guarantee 100% chatbot availability and performance if the provided key does not work (eg. is disabled by OpenAI).
