From Zero to ChatGPT: The Complete Journey of Building Your Own AI Chatbot (VOL-2)

Master Production-Ready AI Chatbots, Large Language Models, Cloud Deployment, RLHF, and the Future of Conversational AI

Author: Anshuman Mishra

Artificial Intelligence is rapidly transforming how people communicate with technology. Modern conversational AI systems are no longer limited to answering simple questions—they can understand complex instructions, assist with business operations, automate workflows, generate content, provide customer support, analyze documents, write software, and power intelligent digital assistants used by millions worldwide.

While Volume I introduced the foundations of conversational AI, chatbot architecture, Natural Language Processing (NLP), Deep Learning, and Large Language Models (LLMs), Volume II takes readers into the professional world of designing, deploying, optimizing, scaling, and managing production-grade AI chatbot systems.

This volume focuses on the engineering practices required to build enterprise-level conversational AI applications. Readers learn how to prepare high-quality datasets, choose the right chatbot frameworks, deploy scalable cloud-based systems, integrate APIs, optimize chatbot performance, evaluate responses, implement Reinforcement Learning from Human Feedback (RLHF), understand AI ethics, and explore the future of next-generation conversational intelligence.

Designed with both academic depth and practical relevance, this book combines modern AI theory with real-world engineering practices used by leading technology companies and AI startups.
