Hey, congrats on all the work you’ve put into your mental health chatbot—sounds like you’ve created something truly unique! Now that you’re ready to take it further, exploring Hugging Face for fine-tuning and machine learning could be a great next step, especially with the strong foundation you’ve built in prompt engineering.
To get started with fine-tuning, you could try 365 Data Science, which is offering free access for 21 days. They have courses on NLP, ML, and working with APIs that could help you bridge the gap between prompt engineering and building a full, custom model. Since you’re familiar with linguistics, I think you’ll pick up the ML and NLP basics quickly, and 365’s courses can walk you through fine-tuning and model integration.
Good luck!
