The Z.AI GLM Coding Plan is a fixed-quota coding subscription from Zhipu / Z.AI for AI IDEs and coding agents. All plans support GLM-5.3 and GLM-5.3-Flash; requests for GLM-5.2/GLM-5.1 route to GLM-5.3, and GLM-4.7 routes to GLM-5.3-Flash (vendor documentation, docs.z.ai). It is not a Kimi plan and is not powered by Kimi K2.5.
Plans start from $18/mo (Lite). Each tier has both a 5-hour credit cap and a weekly credit cap (Lite 2,000 / 10,000; Pro 12,000 / 60,000; Max 28,000 / 140,000). Exact Pro and Max list prices in USD should be confirmed on https://z.ai/subscribe at checkout. Supported coding tools in vendor docs include Claude Code, Cline, and OpenCode (plus listed tools). Vision Understanding, Web Search MCP, Web Reader MCP, and Zread MCP are included on plans per the overview.
Metered GLM-5.3 family API pricing is separate via Z.AI / BigModel pay-as-you-go and should not be conflated with Coding Plan subscription tiers. This listing summarizes vendor-documented product and pricing surfaces only; it does not invent aicoolies Score numbers or a hands-on re-test.
