OpenAI just released GPT-5.3-Codex-Spark, a Cerebras-powered real-time coding model that’s built for speed over deep reasoning — and it’s already live. This “Spark” version of Codex isn’t trying to be the smartest model ever — it’s trying to keep up with your thinking as you code. It's available now for ChatGPT Pro users. Another reason to subscribe to Pro! In this video I’ll show you: • What the 1,000+ tokens/second speed claim actually means in a real workflow.  • A live demo of fast coding iteration in a real macOS app environment.
