Creating Custom GPT with OpenAI GPT Builder: Create, Deploy, and Ethically Scale Production-Ready Conversational AI Agents at an Enterprise Level

Building a custom GPT that works well in the real world takes more than a clever prompt. It calls for clear goals, thoughtful interaction design, careful testing, and a plan for safety and ongoing maintenance. Creating Custom GPT with OpenAI GPT Builder brings those concerns together in a practical guide to creating conversational AI for organizational and business settings.

Noelle Russell, Padmini Soni, and Uvika Sharma take readers from the fundamentals of GPT Builder to the broader work of evaluating, securing, integrating, and scaling AI assistants. The result is a useful perspective for teams that want to build with both capability and responsibility in mind.

Start with the builder, then think beyond the prompt

The early chapters introduce conversational AI, the GPT Builder environment, and the core features behind conversational systems. Examples such as a community concierge give the concepts a hands-on starting point, while discussions of architecture and model selection help place individual design choices in a wider technical context.

Design interactions people can trust

Human-centered design and responsible AI are woven into the book’s practical approach. Readers encounter safety-oriented system prompts, transparency, empathy and accessibility, prompt-injection risks, bias, privacy, and data protection. Case studies—including healthcare scheduling, nutrition advice, and retail customer support—illustrate how these questions arise in different kinds of user experiences.

Test, connect, and maintain your assistant

Creating an assistant is only part of the work. The book also addresses performance testing, debugging, AI red teaming, data handling, and integration with existing systems. Later chapters turn to monitoring, maintenance, scaling, and agentic systems, offering a broader view of what it takes to keep conversational tools useful as needs and environments change.

For builders working across roles

The material speaks to people involved in shaping and evaluating AI systems, including product managers, solution architects, developers, quality and assurance teams, and AI governance or risk professionals. Its emphasis on practical examples alongside questions of oversight makes it relevant to teams considering not only how to build a custom GPT, but also how to make it reliable and responsible for its intended users.

For readers exploring OpenAI GPT Builder in an enterprise context, this book offers a grounded route from first prototype to the wider demands of deployment and continued care.
