Response Format

GLM 5.2 returns OpenAI-compatible completion responses. With stream: true, the response is Server-Sent Events; with stream: false, the response is a single JSON object.

Best Practices

• GLM 5.2 currently supports text-only input through this route.
• Use top_p and top_k together when you need tighter control over output diversity.
• Keep prompts structured when generating long-form content or code.
