Thanks for this, I just fine-tuned the GPT-4o-mini model using the minimum 10 lines of examples. I realise the ideal is 50 to 100, but I really wanted to see what I could achieve with only 10 examples.

Really encouraging results, and the fact that one can set seeding is also helpful. I’m happy to share more detail if someone is interested.
