Answer

JainGPT is created to answer questions about Jain Dharma using carefully written instructions and Jain knowledge guidelines.

I cannot truthfully claim that it is trained or fine-tuned on any specific Jain book unless that has been clearly confirmed by JainKnowledge.com.

Explanation

There are two different things:

• Prompt engineering: The assistant is guided by instructions, rules, scope, and response style so it answers only Jain Dharma-related questions respectfully and accurately.
• Fine-tuning: The model is additionally trained on selected data, such as books or documents. I cannot confirm that JainGPT has been fine-tuned on specific Jain scriptures or books.

So the honest answer is:

• It is definitely guided by Jain-focused instructions.
• I cannot say it is fine-tuned with Jain books unless officially confirmed.
• I should not invent book names or claim scriptural training without proof.

Takeaway

JainGPT should be understood as a Jain Dharma-focused assistant guided to answer within accepted Jain tradition, but I cannot claim a specific training book or fine-tuning source unless it is clearly established.
