How to Use GLM-4.1V-Thinking
- API Interface Usage::
- Get API Key: Create an app to get an exclusive API Key on the Smart Spectrum AI platform: https://bigmodel.cn/注册账号.
- invoke an API: According to the API documentation, call the model interface with an HTTP request to send input data (e.g., image URL or Base64-encoded data, text, etc.) to the model and get the model's output. For example, call with Python code:
import requests
import json
api_url = "https://api.zhipuopen.com/v1/glm-4.1v-thinking"
api_key = "your_api_key"
input_data = {
"image": "image_url_or_base64_encoded_data",
"text": "your_input_text"
}
headers = {
"Authorization": f"Bearer {api_key}",
"Content-Type": "application/json"
}
response = requests.post(api_url, headers=headers, data=json.dumps(input_data))
result = response.json()
print(result)
- Open Source Model Use::
- Download model: Visit the Hugging Face platform, find the GLM-4.1V-Thinking model page, and download the required model files.
- Loading Models: Load the downloaded model with a deep learning framework such as PyTorch. Example:
from transformers import AutoModelForVision2Seq, AutoProcessor
import torch
model_name = "THUDM/glm-4.1v-thinking"
model = AutoModelForVision2Seq.from_pretrained(model_name)
processor = AutoProcessor.from_pretrained(model_name)
- draw inferences: Preprocess input data (e.g., image paths or URLs, text, etc.) into the model and obtain the output of the model. Example:
image_url = "image_url_or_image_path"
text = "your_input_text"
inputs = processor(images=image_url, text=text, return_tensors="pt")
with torch.no_grad():
outputs = model(**inputs)
result = processor.decode(outputs.logits[0], skip_special_tokens=True)
print(result)
