  1. Foundations & Core Concepts

    6 weeks
    Goals
    • Understand LLM fundamentals (tokenization, embeddings, temperature).
    • Learn core Python programming and text processing (regex, string manipulation).
    • Grasp the landscape of AI risks: bias, toxicity, hallucination, copyright.
    • Familiarize with the OpenAI API and basic prompt engineering.
    Resources
    • Fast.ai Practical Deep Learning course
    • OpenAI API documentation & tutorials
    • Google's Responsible AI Practices
    • Python Regex HOWTO
    Milestone

    You can explain LLM risks and use the OpenAI API to generate and manually review content, identifying clear safety issues.

  2. Filtering Tools & Pipeline Construction

    8 weeks
    Goals
    • Master Python for building data processing pipelines (Pandas, requests).
    • Learn to use the OpenAI Moderation endpoint and Hugging Face safety models.
    • Build your first end-to-end filtering service using Flask or FastAPI.
    • Implement basic logging, monitoring, and configuration management.
    Resources
    • Hugging Face Transformers documentation
    • FastAPI tutorial
    • Introduction to Microservices with Docker
    • Prometheus & Grafana getting started guides
    Milestone

    You can build a containerized, API-driven service that takes AI output, passes it through multiple filtering layers (API calls, regex, model), and logs results.

  3. Advanced Systems & Specialization

    10 weeks
    Goals
    • Learn advanced frameworks like LangChain for guardrails and chain-of-verification.
    • Implement dynamic, context-aware filtering using retrieval-augmented generation (RAG) for policy lookup.
    • Design adversarial testing suites and red-teaming exercises.
    • Study specific industry regulations (e.g., GDPR, HIPAA, COPPA) and how they map to filters.
    Resources
    • LangChain documentation (Guardrails, Output Parsers)
    • OWASP Top 10 for LLM Applications
    • Research papers on AI safety (e.g., Constitutional AI)
    • Industry-specific compliance guides
    Milestone

    You can architect a scalable, context-aware filtering system for a complex use case (e.g., a healthcare chatbot), including its monitoring, testing, and compliance documentation.

Practice Projects

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

Real-Time Toxicity & Spam Filter for a Chatbot

Beginner

Build a Python API service that wraps OpenAI's chat completion. Before returning the response, it should pass it through the OpenAI Moderation endpoint and a set of regex rules for spam. Log all requests and filter decisions to a SQLite database.

PII Redaction Pipeline for Healthcare Data

Intermediate

Create a system that ingests text containing fake medical records. Use a pre-trained NER model from Hugging Face to identify and redact personal names, addresses, and medical record numbers. Implement a dashboard (using Streamlit) to visualize redaction accuracy and patterns.

Adversarial Jailbreak Tester & Filter

Advanced

Develop a framework that uses a language model to generate a corpus of potential jailbreak prompts (e.g., 'DAN' prompts, prompt injections). Use these to test and stress-test a target filtering system. Then, build a classifier to detect these jailbreak attempts in real-time based on the prompt structure and style.
