About OpenCSG

OpenCSG is a domestic open-source large model community platform operated by Beijing Kaifang Chuanshen Technology, having secured multiple rounds of financing. Its core product, CSGHub, provides one-stop hosting and collaboration for models, datasets, and code, often referred to as the "Domestic Hugging Face."

Note: Phone number SMS verification is required during registration!

Usage Instructions

The OpenCSG console contains many features. To help you locate common entry points, here is a summary of frequently used sections.

Checking Balance

Click your avatar in the top right corner, go to Personal Information, and select Billing on the left to view your balance. Alternatively, visit directly: https://opencsg.com/settings/billing to check your gifted balance.

Getting API Keys

In the same section (Top Right Avatar - Personal Information), click API Keys on the left to retrieve or create a new large model call key. If you cannot find the entry, you can directly access: https://opencsg.com/settings/api-keys.

Calling Large Model APIs

Navigate to the top menu bar and select [Compute - Model Services] to enter the Model Plaza and view all available callable models.

Honestly, the selection of models is somewhat limited, and most are relatively outdated (with 99 yuan in free credits, who could ask for more?). The only model worth noting is deepseek-ai/DeepSeek-V4.1-Flash. You can use the following command to test the model call:

curl -X POST \
"https://opencsg.com/aigateway/v1/chat/completions" \
-H "Content-Type: application/json" \
-H "Authorization: Bearer your_key" \
-d '{ "model": "deepseek-v4.1-flash", "messages": [{ "role": "system", "content": "You are a helpful assistant." }, {"role": "user", "content": "What is deep learning?" }], "stream": true, "max_tokens": 200, "temperature": 0.2, "top_p": 0.9}'

Note: Replace your_key with your own API key!

Conclusion

OpenCSG offers a 99 yuan credit for large model calls upon registration, supporting models like DeepSeek and GLM, requiring phone verification. The console allows you to check balances, create API keys, and call models. Although the model selection is limited, DeepSeek-V4.1-Flash is definitely worth trying. Use the blogger's invitation link if you need it.
