Zach Moskow(@zachmoskow):This is INSANE. A year ago, GPT-5 was one of the best coding models in the world. 1 billion coding tokens would've been $975. Today, 1 billion tokens on GLM-5.3-Flash costs ~$35. 26x cheaper. This includes avg cache hits on both. And on Arena’s coding leaderboard: - GLM-5.3-Flash: 1531 - GPT-5 High: 1469 I can only image what it will be like this time next year.
