Your question is Fine-Tuning an Open-Source Model. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Walk me through your process for fine-tuning an open-source model for a highly specific domain task.
Explain how you would select the base model, prepare and validate domain data, choose full fine-tuning versus parameter-efficient methods, tune hyperparameters, evaluate domain performance, and deploy the result. Include production considerations such as reproducibility, data leakage, monitoring, rollback, and licensing.
