GLM-5.3 is Z.ai's flagship coding and agentic-engineering model. It shares the GLM-5.2 base model, with all gains delivered through post-training, and always operates with reasoning enabled across three effort levels.
Use GLM 5.3 with a simple API call. OpenAI-compatible endpoint, EU data residency guaranteed.
const response = await fetch("https://api.eurouter.ai/api/v1/chat/completions", {
method: "POST",
headers: {
"Content-Type": "application/json",
"Authorization": `Bearer ${process.env.EUROUTER_API_KEY}`,
},
body: JSON.stringify({
model: "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.
