Gemini AI Chat NPC

For a recent commission, I successfully created a working Gemini AI Chat NPC that lets users choose the Character Instruction.

I opted for Gemini AI over alternatives like ChatGPT because Gemini offers a free tier that doesn’t require payment info—a big plus for me since I’m working on a budget (and I mean that literally; I don’t have more than a penny to spare).

That said, Gemini doesn’t provide OpenCloud API endpoints, which made this project challenging. My goal was to achieve this without spending any money, so I had to get creative.

To make it work, I hosted a Node.js backend server on Glitch, where I created the API endpoints needed to connect with HTTPService in the game and aswell followed the Gemini AI documentation to have the model working properly. While Gemini isn’t entirely free, its free tier has reasonable rate limits and, in my opinion, is a solid option for small-scale developers.

I’m always open to feedback or corrections, so feel free to drop a comment! :smile:

The free tier does have a decent rate limits, so basically you will need to get one of the paid plans to possibly not run into a rate limit fallback message

Thanks! To get it working on Roblox (researching and get the api endpoint working) took around 30 to 40 minutes. The rest like UI and NPC Customization was almost 2 days
