Open Source AI Free Real World Example

Description

Want to get your own local version of ChatGPT up and running but not sure where to start? Checkout HostedGPT and get it running on your own computer or any server that supports Ruby on Rails, just bring your own OpenAI API key. All the core functionality of ChatGPT is already working (e.g. GPT-3.5 and GPT-4, starting new converstions, streaming responses, asking about attached images, etc). It uses Rails 7, Hotwire, Tailwind, SolidQueue and importmap. The main thing missing is the mobile app but that's coming soon.
