From Lisp Generators to AI Streaming: Build Real-Time AI Pipelines with NexaAPI

From Lisp Generators to AI Streaming: Build a Real-Time AI Pipeline with Python Generators & NexaAPI The functional programmer's guide to streaming AI outputs — images, audio, and text, one result at a time. Why Generators Are the Perfect AI Pattern The Lone Lisp generators article trending on HackerNews makes a profound point: generators are semicoroutines that yield control back to their callers. They're lazy. They produce values on demand. This is not just an academic curiosity. It's the exact pattern you need for modern AI APIs. Think about it: Text generation : tokens arrive one at a time → generator yields each token Image generation : batch of prompts → generator yields each image as it completes TTS audio : sentences → generator yields each audio chunk Video frames : generator yields each frame as it renders Every AI streaming use case maps naturally to the generator pattern. If you've been writing Lisp (or Haskell, or Clojure), you already have the mental model. You just need
