AI-Powered-App

This is a project that demonstrates how to use several AI technologies:

• OpenAI chat completion API
• Deepgram speech-to-text API
• Replicate API to run the miniGPT vision encoder model
• gpt-3-encoder package to tokenize strings into tokens (which are used to set limits on the length of prompts sent to OpenAI)
• Langchain model, chain, and memory interfaces
