How Using Fetch with the Streams API Gets You Faster UX with GenAI Apps

This text discusses the use of Generative AI and large language model (LLM) APIs for building innovative interfaces. It highlights that waiting for full LLM responses can slow down user interface updates, but most LLM APIs provide streaming endpoints to stream responses as they are generated. The text then demonstrates how JavaScript fetch can be used to update front-end applications in real time while an LLM generates output, improving the user experience. It also covers server-sent events and their use with a POST request for sending structured data. Finally, it mentions that understanding how to stream responses from a web server is crucial for creating great user experiences when working with LLMs.
