GLM-5.3 is Z.AI's open-weight, text-only reasoning model for complex coding, long-horizon agentic work, tool use, and multilingual chat. It uses the same base model as GLM-5.2, with its gains coming from post-training.
Use GLM 5.3 with a simple API call. OpenAI-compatible endpoint, EU data residency guaranteed.
const response = await fetch("https://api.eurouter.pro/api/v1/chat/completions", {
method: "POST",
headers: {
"Content-Type": "application/json",
"Authorization": `Bearer ${process.env.EUROUTER_API_KEY}`,
},
body: JSON.stringify({
model: "zhipu/glm-5.3",
messages: [
{ role: "user", content: "Hello!" }
],
}),
});
const data = await response.json();
console.log(data.choices[0].message.content);You need AI that won’t create compliance headaches. Your data stays in the EU, GDPR is enforced by default, and every request is routed for the best balance of cost, latency, and uptime, reducing risk while improving performance.
