Fine-Tune a Large Language Model

Assess ML engineers on real LLM fine-tuning — not just Hugging Face tutorials.

Fine-tune a transformer-based LLM on the CNN/DailyMail dataset for text summarization. Preprocess data, configure training, evaluate using ROUGE and BLEU metrics, and generate high-quality abstractive summaries.

Common Questions

Frequently Asked Questions

What model can I use for this fine-tuning lab?
You can use any pretrained transformer model compatible with the Hugging Face Transformers library, such as BART or T5. Choose a model suitable for abstractive summarization and the available compute resources.
How long does the LLM fine-tuning lab take?
The lab is designed for 90 minutes. This covers data exploration, preprocessing, tokenization, model fine-tuning, evaluation with ROUGE and BLEU metrics, and generating test set summaries.
What evaluation metrics are used?
Your submission is evaluated using ROUGE-1 (≥0.30), ROUGE-L (≥0.25), and BLEU (≥15.0) scores, measuring content coverage, structural quality, and summary fluency respectively.
What dataset is used in this lab?
The lab uses the CNN/DailyMail dataset provided as train_df.csv and test_df.csv. Each entry contains an article, its highlights (summary), and a unique ID for alignment.
What format should the output file be in?
You must generate a submission.csv file with two columns: 'highlights' containing your generated summaries and 'id' matching the test set entries.
Is this lab suitable for hiring ML engineers?
This lab is specifically designed for evaluating ML engineers, MLOps engineers, and AI developers on their ability to fine-tune LLMs, handle training pipelines, and produce quantitative evaluation results.
