Description:
An application to hold conversations using the OpenAI API to access the GPT-3.5-Turbo model and the GPT-4 model.
Very versatile and lets you edit the conversation's past to change the future responses.
Let's you save/load/delete conversations and agents using JSON flatfiles.
Programmed using PHP 8. Uses jQuery CDN for jQuery. PHP Curl required to connect to API with class.phpopenaichat.php.
I found ChatGPT to be lacking, so I made my own.
Messages in conversation only show an excerpt. Click on them to see the full message.
*/
/*
Features:
- uses class class.phpopenaichat.php to drive the application's API request.
- Persistent conversation using $_SESSION
- Persistent controls that dynamically update on the server side whenever they are changed client side
- Using jQuery to dynamically update the page without reloading it
- Ability to save/load/delete conversations in a JSON file in the _saved directory (create in this program's root, and set as read/writeable
- Ability to edit previous conversation messages by clicking on them in the window (Both agent and user messages can be edited)
- Ability to save/load/delete agent into a JSON file in the _saved_agents directory (create in this program's root, and set as read/writeable
- Minimal CSS styling for better code clarity
- Ability to change the model, temperature, frequency penalty, presence penalty, and max tokens, previous conversation, and agent between prompts
- frequency penalty, presence penalty let the AI know to not repeat itself or to not repeat the user's input
- temperature is how random the AI's response is. 0.0 is the most predictable, 1.0+ is the most random
- agents help the model align to a specific style of conversation. (ie. a doctor, a lawyer, a child, a teenager, a parent, etc.)
- multiuser - Can run multiple instances at same time, but just use different browsers or a private window so that each instance has its own session.
- GPT 4 is in beta at the moment, so you have to request access.
- API access costs money, so be aware of that. (gpt 3.5 turbo is dirt cheap at the moment)
- This is not secured for production use. It is just a proof of concept, and made for closed/private access from trusted individuals.
- Using a command processor on the return from the server let's the server dynamically redefine the controls on the client side.
- server has a copy of the clients data, so client's side is more of an indicator than a director.
- API can take a few seconds to return a response, so be patient when it seems nothing is working after sending a prompt.
devnotes: june 2023
- added to example:
- added support for gpt-3.5-turbo-16k (16k token model of gpt-3.5-turbo)
- added support for gpt-4-32k (32k token model of gpt-4)
