Chinese startup Z.ai made its GLM-5.3 model callable through its programming interface at the same rates as the previous version, $1.40 per million words in and $4.40 per million out. Independent testing by Artificial Analysis scored it level with Moonshot's Kimi K3 as the strongest openly available model. The model is more talkative than its predecessor, so cost per completed task rose even though per-token prices did not, and the promised open weights have no release date.
