Transform your JavaScript expertise through the power of Open AI API models using “Creating ChatGPT Apps with JavaScript.” This book will guide JavaScript developers to build smart applications while providing tangible knowledge of OpenAI’s API for text summarization, creating transcripts from audio files, generating images, and running models locally on your machine.

Through hands-on projects and code examples, readers will discover how to build AI-powered apps from scratch, such as using embeddings to train a Discord bot to answer customers’ questions in multiple languages. Readers will also learn to dictate text for writing articles or blogs with a localized integration of Whisper and generate hero images with Dall-E. What’s more, in the final chapter of this book, you’ll be able to maximize productivity by creating a Smart Assistant like Alexa or Siri with JavaScript and the new Raspberry Pi 5.

From seasoned developers to newcomers, this book offers something for everyone. Not only will readers learn to build apps with ChatGPT and JavaScript, but they will also learn best practices for prompt engineering. They’ll understand how AI models can enhance workplace efficiency and utilize natural language processing (NLP) to make interactions with applications feel…well, natural. The end result is expert knowledge in leveraging ChatGPT programmatically and incorporating the technology into diverse applications.
