GPT-5.3 Codex Spark Just Changed Coding Forever! ⚡ #ainews #ai #openai
OpenAI just dropped GPT-5.3-Codex-Spark, and it’s built for pure speed.
Released on February 12, 2026, this new research preview is a high-speed coding model powered by the Cerebras Wafer-Scale Engine 3 — delivering over 1,000 tokens per second.
That means near-instant code edits, real-time logic restructuring, and lightning-fast interface updates.
Unlike the full GPT-5.3-Codex, this version is optimized for low-latency, interactive development instead of long reasoning tasks.
It features a 128k context window and is currently available to ChatGPT Pro users via the Codex app, CLI, and VS Code extension.
Is this the future of live AI coding? 👀
