  3. Safety, Red-Teaming, and Adversarial Testing

    4 weeks
    Goals
    • Learn red-teaming methodologies for LLMs: prompt injection, jailbreaking, data extraction attacks
    • Study AI safety taxonomies and content policy frameworks (OpenAI usage policies, Anthropic's constitutional AI principles)

Practice Projects

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

LLM Hallucination Detector

Beginner

Build a pipeline that takes a question, a retrieved context, and an LLM answer, then scores the answer for factual grounding and hallucination using both rule-based and LLM-as-judge approaches. Test against TruthfulQA and custom medical/legal datasets.

~25h
Python evaluation scriptingLLM-as-judge prompt designRAG evaluation metrics

Multi-Model Benchmark Comparison Dashboard

Beginner

Create an interactive dashboard that evaluates 3-5 LLMs (GPT-4, Claude, Llama, Gemini) on a standardized set of test cases across dimensions like accuracy, safety, and instruction-following. Visualize comparative strengths and weaknesses.
