GLM-5.3-FlashX
Break down what GLM-5.3-FlashX really changes: how throughput reaches 200 tokens per second without moving the capability positioning, what it means to price low latency as its own tier, and the inference work behind it.
GLM-5.3-FlashX is a production-grade performance tier built on GLM-5.3-Flash: the same capability positioning, but output throughput raised to 200 tokens per second, roughly five times faster than the previous version at 2.5 times the price, with the API open at launch. It prices low latency as a tier so coding agents, realtime chat and tool calls wait less, running on a cluster of more than a hundred thousand Chinese-made AI accelerators.
