AILabox's 2026-08-25 crawl found GLM-5.3 listed on Zhipu's open platform at ~$1.19/1M input and ~$4.15/1M output, matching GLM-5.2.
On August 25, 2026, AILabox's crawl of Zhipu AI's open platform (open.bigmodel.cn/pricing) found GLM-5.3 officially listed, with a matching ZHIPU/GLM-5.3 entry appearing on OpenRouter at the same time.
GLM-5.3 is priced the same as GLM-5.2: approximately $1.19 per million input tokens and $4.15 per million output tokens (converted at the 2026-08-25 FX rate). Compared with GLM-5.1, input pricing is slightly higher while output pricing is roughly unchanged.
The same crawl confirmed the availability and prices of GLM-5.2, GLM-5.1, GLM-5-Turbo and other models, all updated to the 2026-08-25 check date in AILabox data.
The GLM family is widely used across Chinese developer toolchains. Launching a new version at the same price makes it a low-cost upgrade path for existing GLM-5.2 users.
