The Z.ai Coding Plan (also known as the GLM Coding Plan) is a subscription service from Chinese AI startup Z.ai that provides developers with flat-rate access to the GLM model family for AI-powered coding tasks, supporting models including GLM-5, GLM-5-Turbo, GLM-4.7, GLM-4.6, and GLM-4.5. Starting at just $10/month for the standard Lite plan and $30/month for the Pro plan, with promotional first-month pricing of $3 and $15 respectively, the plan is positioned as one of the most affordable pathways to high-quality AI coding assistance. Z.ai's aggressive pricing strategy has made it a popular choice among developers using bring-your-own-key coding tools.
The Z.ai Coding Plan Lite tier provides approximately 120 prompts within a 5-hour rolling cycle, while the Pro plan offers 600 prompts per 5-hour cycle, with a rate-limiting approach that ensures sustained availability rather than hard monthly caps. All plans include Vision Understanding, Web Search MCP, Web Reader MCP, and Zread MCP capabilities that extend the coding assistant's abilities beyond pure code generation. The plans are compatible with popular AI coding tools including Claude Code, Cline, OpenCode, and Kilo Code, allowing developers to use Z.ai's models as drop-in replacements for more expensive providers.
The Z.ai Coding Plan targets budget-conscious developers, indie hackers, and startup teams who want functional AI coding assistance without the $20-200/month price tags of Western alternatives. It is particularly popular among developers experimenting with vibe coding workflows and those who use high volumes of AI interactions during development sprints. Z.ai competes in the same affordable AI coding plan segment as Alibaba Cloud, Kimi, and MiniMax, with its partnership with Cline being a notable distribution channel that has driven adoption among the open-source AI coding community.
