  1. Foundations of Conversational AI

    4 weeks
    Goals
    • Understand core concepts of dialogue systems: intents, entities, dialogue acts, and conversation states
    • Learn Python basics and API consumption patterns for calling LLM endpoints
    • Study conversation design principles including turn-taking, repair strategies, and escalation flows
    Resources
    • Google's 'Conversation Design' guidelines
    • OpenAI API documentation and quickstart guides
    • Coursera: Building AI-Powered Chatbots Without Programming (IBM)
    • Book: 'Designing Bots' by Amir Shevat
    Milestone

    You can design a simple multi-turn chatbot using the OpenAI API with a structured system prompt and basic error handling.

  2. Prompt Engineering and LLM Orchestration

    6 weeks
    Goals
    • Master prompt engineering patterns: few-shot, chain-of-thought, role-based, and structured output
    • Learn LangChain fundamentals including chains, memory modules, and output parsers
    • Implement a basic RAG pipeline using a vector database and document loader
    Resources
    • LangChain documentation and Harrison Chase's tutorials
    • OpenAI Cookbook (advanced prompt patterns)
    • DeepLearning.AI short courses: LangChain for LLM Application Development
    • HuggingFace NLP Course (selected modules)
    Milestone

    You can build a RAG-powered chatbot that answers questions from a document store with proper source attribution using LangChain and Pinecone.

  3. Agentic Dialogue and Tool Integration

    6 weeks
    Goals
    • Implement function calling and tool-use patterns for action-oriented dialogue
    • Build multi-agent or graph-based dialogue orchestration with LangGraph
    • Integrate dialogue systems with external APIs (CRM, booking, payment) via structured tool schemas
    Resources
    • LangGraph documentation and example notebooks
    • OpenAI function calling and Assistants API guides
    • Anthropic tool-use documentation
    • GitHub repos: real-world agentic chatbot examples
    Milestone

    You can build an agentic chatbot that performs multi-step tasks - like booking appointments or retrieving account information - through orchestrated tool calls.

  4. Evaluation, Safety, and Production Hardening

    5 weeks
    Goals
    • Design and implement dialogue evaluation frameworks combining automated metrics and human review
    • Build guardrails for hallucination detection, PII redaction, and content policy enforcement
    • Learn production deployment patterns: logging, monitoring, observability, and rollback strategies
    Resources
    • LangSmith documentation for tracing and evaluation
    • NeMo Guardrails by NVIDIA
    • AWS Well-Architected ML Lens (operational best practices)
    • PromptLayer observability tutorials
    Milestone

    You can deploy a production-grade dialogue system with evaluation pipelines, guardrails, monitoring dashboards, and a documented escalation path.

  5. Voice, Multimodal, and Enterprise Scale

    4 weeks
    Goals
    • Integrate speech-to-text and text-to-speech pipelines for voice-enabled dialogue systems
    • Design dialogue systems that handle multimodal inputs (text, image, structured data)
    • Architect multi-tenant or multi-locale dialogue platforms with compliance awareness
    Resources
    • OpenAI Realtime API and Whisper documentation
    • Amazon Polly and Google Cloud Speech API guides
    • Enterprise CX platform documentation (Genesys, NICE, Five9)
    • Case studies: large-scale conversational AI deployments
    Milestone

    You can architect and pitch an enterprise-scale conversational AI solution spanning voice and text channels with compliance and multi-language support.
