Z.ai revealed that Ox Alpha is actually GLM-5.3-Flash, powered by tens of thousands of domestic Chinese accelerators rather than NVIDIA GPUs. The model uses a MoE architecture with 320B total params but only 18B active during inference. It achieves a 10x cost reduction and significant benchmark improvements (DeepSWE 46.2->63.4) over GLM-5.2, utilizing linear attention to cut compute and KV cache size.
