What model should be used for creating email templates online in Google AI Studio?

For creating email templates online, GPT-3.5 Turbo is the recommended model. It provides an excellent balance of cost and performance, making it ideal for automating email responses. After selecting this model in Google AI Studio, users need to add a prompt in the messages field - something like 'Write a short response to this email.' This creates a starting point for email automation, after which the specific email content can be mapped to be included in the prompt.
