GLM 5.3 Derisked API: a 5-minute quickstart

AI-generated illustration

GLM 5.3 Derisked is on the Vani API with the same interface as OpenAI's. If your code or tool can talk to OpenAI, it can talk to GLM 5.3 Derisked. Here's how to make your first call.

1. Get an API key

Create a key on the Vani API Platform. Keep it secret: it works like a password.

2. Point your client at Vani

3. Make a request

curl

curl https://api.vani.ai/v1/chat/completions \
  -H "Authorization: Bearer $VANI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "zhipu/glm-5.3-derisked", "messages": [{"role": "user", "content": "Hello!"}]}'

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(base_url="https://api.vani.ai/v1", api_key="YOUR_VANI_API_KEY")
reply = client.chat.completions.create(
    model="zhipu/glm-5.3-derisked",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(reply.choices[0].message.content)

JavaScript or TypeScript (OpenAI SDK)

import OpenAI from "openai";

const client = new OpenAI({ baseURL: "https://api.vani.ai/v1", apiKey: process.env.VANI_API_KEY });
const reply = await client.chat.completions.create({
  model: "zhipu/glm-5.3-derisked",
  messages: [{ role: "user", content: "Hello!" }],
});
console.log(reply.choices[0].message.content);

Streaming works the usual way: set stream: true. System prompts work too. Vani also has an Anthropic-compatible /v1/messages endpoint, so tools built for that format can use GLM 5.3 Derisked as well.
