🔥OpenAI launches GPT-5.3-Codex-Spark in research preview OpenAI has released GPT-5.3-Codex-Spark, a lightweight, ultra-fast variant of GPT-5.3-Codex built for real-time coding workflows. It’s designed to feel nearly instant when editing and iterating code, complementing the original Codex which focuses on deeper, longer-running tasks. GPT-5.3-Codex-Spark might quietly be the most important AI release of the year so far. 1000+ tokens per second isn’t just faster… it changes how humans and machines build together. Real-time creation is no longer a concept, it’s here. https://openai.com/index/introducing-gpt-5-3-codex-spark/ @aipost 🏴
