AI Popular Systems: Architecture, Capabilities, and Comparative Analysis

AI Popular Systems: Architecture, Capabilities, and Comparative Analysis provides a comprehensive and objective examination of today's leading artificial intelligence platforms, including ChatGPT, Claude, Gemini, Microsoft Copilot, Meta Llama, Mistral, Gemma, Hugging Chat, Zapier AI, and other emerging systems. Using a consistent analytical framework, the book explores each platform's architecture, capabilities, integration options, scalability, customization, ethics, transparency, cost, community support, and practical applications. Rather than focusing on marketing claims, it presents a balanced technical assessment that enables meaningful comparison across AI ecosystems. Designed for researchers, graduate students, AI engineers, software architects, educators, and technology leaders, the book serves as both a reference and a practical guide for understanding the rapidly evolving landscape of modern artificial intelligence. A companion volume, Practical Benchmarking and Hands-On Evaluation of AI Popular Systems, complements this work through experimental studies and comparative performance evaluation.
