GLM 5.3 Flash just dropped on OpenRouter.
This is Ox Alpha. The mystery model that went viral last week. Now you can run it under its real name.
$0.075 input. $0.25 output per million tokens. That is cheaper than DeepSeek V4 Flash. 1M context. Multimodal. Open weights coming.
A Chinese lab just dropped a frontier coding model for half the price of the cheapest model in AI.
The price war is over. Open source won.
