Reducing Costs with local hosting and small AI

Moved my side project to a local host. Am using ChatGPT plus to work with VS Code and Powershell on my home computer. Open Code with big pickle was added for a small AI. I am wondering if this is the best most affordable setup. The goal is to reduce my costs by hosting locally and using small AI to keep costs down. Wondering if this is the best way to do this. My computer uses an NVIDIA RTX 5060 so I can do the smallest of desktop AI. Will eventually migrate it back to a regular host like Railway. Trying to get the process right and keep the costs down as part of the process. Any suggestions on small AI or what to do as part of the process.
