    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.

    Attachment settings

    • 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.

    Attachment settings

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

  • 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:
Attachment settings
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:
Attachment settings

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

Troubleshooting

AI Labs extension maintains internal logs, you should have admin or moderator rights to see log icon:
Attachment settings

You can see entire AI communication history in the log:
Attachment settings
If Log entry is empty it ususally means that /ailabs/* routes blocked by one of phpBB extensions (eg Login Required) and you will need to add /ailabs/* to extension whitelist.
You can examine Log response (JSON) to see details for AI response.
Please feel free to post your quesions or concerns at https://github.com/privet-fun/phpbb_ailabs/issues.
