GLM-5.1 works with all the major coding agents - Claude Code, OpenCode, Kilo Code, Roo Code, Cline, and Droid. This guide covers setup for each, plus tips for getting the most out of GLM-5.1's long-horizon capabilities in agentic workflows.

1GLM Coding Plan Setup

First, subscribe to the GLM Coding Plan at z.ai/subscribe. This gives you API access to GLM-5.1 across all supported coding agents. Pricing uses a quota system: 3× during peak hours (14:00–18:00 UTC+8), 2× off-peak, with a promotional 1× off-peak rate through April 2026.

2Claude Code Configuration

Update your Claude Code settings to use GLM-5.1:

Claude Code's think mode works well with GLM-5.1 for complex reasoning tasks. The model's long-horizon capabilities shine when given extended tool-call budgets.

3OpenCode Setup

OpenCode supports GLM-5.1 through the Z.ai API endpoint. Configure your provider settings to point to the Z.ai API with your Coding Plan credentials.

4Kilo Code & Roo Code

Both Kilo Code and Roo Code support custom model endpoints. Add the Z.ai API as a custom provider with the model name GLM-5.1 and your API key from the Coding Plan dashboard.

5Cline & Droid

Cline and Droid both support OpenAI-compatible API endpoints. Configure the base URL to https://api.z.ai/v1 and select GLM-5.1 as your model.

6Z Code: Multi-Agent GUI

Zhipu AI offers Z Code - a GUI that supports multiple agents working together. Key features:

• Develop on remote machines over SSH
• Kick off tasks from your phone and check back later
• Multiple agents collaborating on the same codebase
• Built-in support for GLM-5.1's long-horizon capabilities

7Optimizing for Long-Horizon Tasks

To get the most out of GLM-5.1's sustained optimization capabilities:

• Use extended tool-call budgets - GLM-5.1 improves over hundreds of iterations
• Set temperature=1.0, top_p=0.95 to match benchmark configurations
• Use 200K context windows for complex multi-file tasks
• Let the model self-review and iterate rather than interrupting with new prompts

8Lushbinary Agentic Workflows

At Lushbinary, we build custom agentic workflows powered by frontier models like GLM-5.1. From coding agent configuration to production pipeline automation, we help teams get the most out of AI-assisted development.
