Is The New OpenAI Model Actually THAT Fast?

Matt Wolfe



OpenAI just dropped GPT-5.3-Codex-Spark that's supposed to be just as good as Codex but faster.

Thanks to a partnership with Cerebras (the chip makers), this model is optimized to build quickly.

I tested it live with a “Vampire Survivors” style prompt and in under a minute, I had a playable game called “Nocturne Survivors” with functioning XP, leveling, and upgrade systems.

But right now it's only on the $200/mo Pro plan.
