I went with the second one to try it out, feels pretty okay (with OpenCode, though Claude Code would also work), however it feels like I reach the weekly limits somewhat fast with their 65 USD Pro subscription. They also have that whole peak times thing going on and apparently it will get worse after September:
> Supported models and Visual Understanding MCP share the same usage quota. GLM-5.2 and GLM-5-Turbo consume quota at 3x during peak hours and 2x during off-peak hours. Limited-time benefit: off-peak usage is currently charged at only 1x quota through the end of September. Peak hours: 14:00–18:00 daily (UTC+8).
The simplest would be either OpenRouter: https://openrouter.ai/z-ai/glm-5.2
Or grabbing their GLM Coding Plan directly: https://z.ai/subscribe

OpenRouter, Z.ai coding plan, OpenCode Go, OpenCode Zen .. and probably more.
