OpenAI's fine-tuning model can be used on TypingMind. Here are 3 simple steps to set it up:
First, log into your OpenAI API account at https://platform.openai.com and go to “Fine-tuning”

Click “Create new” and select the GPT-3.5-turbo as the base model (TypingMind doesn’t support other base models now)
Upload the .jsonl file to use for training, please follow the OpenAI instructions to create the file.

Once you're done with all of that, you'll get the model ID.

Head over to typingmind.com, click "Models" on the left side panel. Then, select “Add Custom Model”.
