Released 8 days after GLM-5.3 · All Z.ai releases
GLM-5.3-Flash is a natively multimodal model from Z.ai with 320B total / 18B active parameters. Its hybrid sparse-and-linear attention architecture keeps long-context behaviour accurate while cutting compute overhead, and it targets efficient coding and long-horizon agent tasks.
GLM-5.3-Flash runs on 9 different routes through the qynio gateway. Compare residency, zero retention, and training posture at a glance — full data-handling detail per route below.

GLM-5.3-Flash runs on 3 independently monitored routes through the qynio gateway. A direct integration leaves you on one of them, the gateway serves whichever is healthy.
Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. 6 further routes for this model are not on the board yet and are not counted above. See uptime for every provider qynio monitors.
Each route hosting GLM-5.3-Flash has its own privacy posture, residency, and no-KYC terms. Postures are maintained by qynio with a last-verification timestamp.

Call GLM-5.3-Flash through the qynio gateway with one API key. Let your coding agent set it up, or call it directly — qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.
Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.
import OpenAI from "openai";const client = new OpenAI({apiKey: process.env.QYN_API_KEY,baseURL: "https://api.qyn.io/v3/compat",});const completion = await client.chat.completions.create({model: "berget/zai-org/GLM-5.3-Flash",messages: [{ role: "user", content: "Hello" }],});console.log(completion.choices[0].message.content);
