GLM 4.7 Flash
VerifiedFast proprietary LLM built for long-context text tasks.
About GLM 4.7 Flash
GLM 4.7 Flash uses a transformer-based design optimized for speed while supporting an unusually large text context. As a proprietary offering from Z.AI, it remains unavailable for local weight inspection or modification. The flash variant emphasizes low-latency inference on text-only workloads.
Its primary strengths lie in managing lengthy documents, multi-turn dialogues, and detailed content synthesis without truncation. Typical usage includes enterprise chat systems, automated summarization pipelines, and any workflow that benefits from a 200k-token window under a hosted API.

Quick start
OpenRouter's API is OpenAI-compatible — most SDKs work by just swapping the base URL. Only the model slug changes between models.
import OpenAI from "openai";
const client = new OpenAI({
baseURL: "https://openrouter.ai/api/v1",
apiKey: process.env.OPENROUTER_API_KEY,
});
const completion = await client.chat.completions.create({
model: "z-ai/glm-4.7-flash",
messages: [{ role: "user", content: "Hello!" }],
});
console.log(completion.choices[0].message.content);Model slug: z-ai/glm-4.7-flash
