ChatGPT basic setup

• You will need OpenAI account, sign up at https://platform.openai.com/.
  To obtain API key go to https://platform.openai.com/account/api-keys, click on Create new secret key, copy and save in a safe place generated API key.
  Open AI key starts with sk- and look something like this sk-rb5yW9j6Nm2kP3Fhe7CPzT1QczwDZ5LvnlBfYU2EoqyX1dWs.

• Create new board user who will act as AI bot, for our example we will use user ChatGPT.
  Make sure this user account is activated and fully functional.

• Got to ACP > Extensions > AI Labs > Settings and add new configuration, select chatgpt from AI dropdown:

  • Use Load default configuration/template to get defaults.
    Replace Configuration JSON api-key with your Open AI key.
  • Select forums where you want ChatGPT AI user to reply to new posts and/or to quoted and @mention (if you are using Simple mentions extension) posts.

• Save changes, navigate to forum configured above and create new post (if you configured Reply on a post) or quote/@mention ChatGPT user:

• Fine-tuning can be done by adjusting following OpenAI API chat parameters https://platform.openai.com/docs/api-reference/chat

  • model, default gpt-3.5-turbo, full list of models available at https://platform.openai.com/docs/models
  • temperature, top_p, frequency_penalty and presence_penalty - see https://platform.openai.com/docs/api-reference/chat/create

• Additional setting used by ChatGPT AI

  • message_tokens, default 4096, limit maximum size of the entire conversation thread
  • max_tokens, default 1024, define size reserved for AI reply when quoted
  • prefix, default empty, can be used to prompt model
  • prefix_tokens, default 0, copy above prefix to https://platform.openai.com/tokenizer to get size of your prefix in tokens and update prefix_tokens with number returned by tokenizer

ChatGPT advanced setup

You can setup ChatGPT to pretend it is somebody else.
Let's create new board user Bender and configure as shown below:

Notice we used prefix and prefix_tokens to fine-tune ChatGPT AI behaviour.
Our AI bot Bender will provide responses like this, mostly staying in a character.

DALL-E setup

Setup mostly the same as for ChatGPT above:

Refer to https://platform.openai.com/docs/api-reference/images/create to learn more about n and size parameters.
Examples

DALL-E advanced features

• To generate an image of the desired size, you can specify one of the following sizes anywhere within the prompt, example:

  • 1024x1024
  • 512x512
  • 256x256

• To create variations of the image simply post image url to the prompt, example

Stable Diffusion setup

• You will need Stability AI account, follow official instructions https://platform.stability.ai/docs/getting-started/authentication to create account and obtain API key.

• Create new board user, let's say Stable Diffusion and create configuration:
