What is GLM 4.7 Flash?
GLM 4.7 Flash (model name: glm-4-flash) is Zhipu AI's speed-optimized language model designed for applications where response time is critical. It's part of the GLM-4 family but uses distillation and quantization techniques to deliver 3-5x faster inference while maintaining impressive quality.
Key Highlights
- Ultra-Fast Inference: Average response time under 1 second for typical queries
- Completely Free: No cost on official Zhipu AI platform (with rate limits)
- High Quality: 85-90% of GLM-4-Plus quality at 5x the speed
- 128K Context: Same long-context capability as other GLM-4 models
- Multilingual: Strong Chinese and English support
The GLM 4.7 Flash API is ideal for chatbots, real-time assistants, customer service automation, and any application where users expect instant responses.

How to Use GLM 4.7 Flash API
Using the GLM-4-Flash API is identical to other GLM models - just specify the model name:
import requests
API_URL = "https://open.bigmodel.cn/api/paas/v4/chat/completions"
API_KEY = "your-api-key"
def chat_with_flash(user_message):
headers = {
"Authorization": f"Bearer {API_KEY}",
"Content-Type": "application/json"
}
data = {
"model": "glm-4-flash", # The key difference!
"messages": [
{"role": "user", "content": user_message}
],
"temperature": 0.7,
"max_tokens": 1000
}
response = requests.post(API_URL, headers=headers, json=data)
return response.json()['choices'][0]['message']['content']
answer = chat_with_flash("What is machine learning?")
print(answer)
