About

This is a Bank ChatGPT AI Plugin POC to observe how ChatGPT will perform with additional banking transaction skills.

This repo uses Semantic Kernel with two ChatGPT Plugins. It is inially created using code taken from the following:

Demo Script

Setup

  1. Run all 3 plugins with start.bat
  2. Run the Semantic Kernel Chat Copilot Locally with ~\scripts\start.ps1
  3. Go to http://localhost:3000/, and login using the proper Entra ID credentials (if applicable)
  4. Go to Plugins, and add all 3 plugins as Custom Plugins: http://localhost:7071, http://localhost:7072, and http://localhost:7073
  5. Enable all 3 added plugins
  6. Go to Persona, and add a persona metaprompt (see sample below). Don't forget to Save.
  7. Start chatting.

Chat Messages

  1. List available accounts
List all my accounts.
  1. Transfer funds
Transfer $1000 from my savings account to my current account.
  • If this throws an error, check the input JSON of the Transfer API. It should be something like this { "sourceAccountNumber": "$SAVINGS_ACCOUNT_NUMBER", "destinationAccountNumber": "$CURRENT_ACCOUNT_NUMBER", "amount": 1000, "remarks": "Transfer initiated by user" }
  1. Update billing address
Update my address, I now live in 123 Margrave Road, USA

Learning Notes

These are the learnings from my experimentation so far...

  1. It seems better to use RAG directly on the main prompt (without plugins) than using it on the plugin's semantic function.
  • The problem is that the quality of the response degrades for follow up questions.
  • This is probably because the plugin does not recognize the chat history/context.
  • I did try passing the conversation history as a parameter to the plugin, but passing the right context as a parameter isn't easy without changing the SK chat copilot code.
  1. Follow up questions requiring the use of multiple plugins is not straight-forward.
  • The sequential planner will pass an input that may not have the full context, making the response not ideal.
  • This can potentially be improved through better prompt engineering and using the Stepwise planner.
  1. Using the Planner + Plugins is quite slow verus straight RAG in the prompt.
  • This is expected, but it is still worth noting.
  • This can be improved using predefined plans, but the chat copilot app does not support this yet for me to test further.
