  3. RAG Pipelines, Fine-Tuning, and Clinical Knowledge Grounding

    6 weeks
    Goals
    • Build end-to-end RAG pipelines using LangChain + vector databases for clinical content retrieval
    • Fine-tune open-source LLMs (Llama, Mistral) on mental health conversation datasets using LoRA/QLoRA
    • Implement evaluation frameworks using DeepEval and Ragas for safety and relevance scoring
    • Design clinician review workflows and feedback loops for continuous improvement

    • Paper: 'Pi: A Clinically-Inspired Conversational AI' (Inflection AI)
    Milestone

    You can build a RAG-powered therapy chatbot that retrieves clinically grounded responses and pass automated safety evaluations

  4. Safety Engineering, Crisis Detection, and Guardrails

    5 weeks
    Goals
    • Implement multi-layer crisis detection: keyword, sentiment, intent classification, and LLM-as-judge
    • Build human-in-the-loop escalation pipelines connecting chatbot to live crisis counselors
    • Conduct adversarial red-teaming on your chatbot using curated attack prompt libraries
