Does Calculus AI use external GPT models?

Calculus AI  can be configured to use a specific Large Language Model such as Open AI’s GPT3.5 or Google Bard for the generative AI features.
CRM Administrators can choose the model from the Calculus AI GPT Configuration page. 

Calculus AI also supports fine-tuned models that are trained on your data. Vtiger offers professional services to help build fine-tuned models based on your Knowledge Base.
By default, it uses Open AI’s GPT3.5, which is an LLM trained on public data available before June 2021.
