Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

Tune a 'Helpful Assistant' Model

Beginner

Fine-tune a base model like Mistral-7B or Llama-3-8B on a curated dataset of general helpful instructions (e.g., Alpaca, OpenAssistant). Focus on SFT and basic evaluation.

Build a Domain-Specific Expert

Intermediate

Tune a model to excel in a specific vertical, like legal document Q&A or medical query parsing. This involves sourcing or creating a specialized instruction dataset and evaluating against domain-specific metrics.

Domain Data CollectionSpecialized Evaluation DesignParameter-Efficient Fine-Tuning (LoRA)

Implement a Full RLHF/DPO Pipeline

Advanced

Take a base SFT model and align it using either RLHF or DPO. This requires creating a preference dataset (e.g., by rating model outputs), training a reward model (if using RLHF), and running the alignment training loop.

Develop a 'Model Self-Improvement' Engine

Advanced

Create a pipeline where the model generates its own instruction/response pairs, a judge (human or LLM) filters them, and the high-quality synthetic data is fed back into the next tuning cycle. Focus on avoiding feedback loops that degrade quality.
