    Create Dedicated Inference Instance

    Access Entry

    On the model details page, click the Deploy Model button in the top right corner, then select Dedicated Instance from the dropdown menu to navigate to the creation page.

    Note

    Only some models support creating dedicated instances. If the desired model does not have a "Dedicated Instance" option, contact the platform administrator.

    Configuration Parameters

    On the dedicated instance creation page, fill in the following configuration, then click Create Instance:

    Parameter Description
    Instance Name Custom name; must not duplicate existing instances
    Model ID The model identifier on the platform; defaults to the current model
    Min / Max Replicas Replica range. When the minimum is 0, the instance shuts down automatically after 1 hour with no requests
    Region/Resource Config Select a compute specification. The page shows Recommended Minimum GPU Memory; cards below that value are marked Low Memory. A multi-node specification locks the replica count and cannot scale to 0
    Runtime Framework Choose the framework (vLLM, SGLang, TGI, or llama.cpp), then the framework version. Multi-node inference supports only vLLM and SGLang
    Engine Args Collapsed. Tunable options for the selected framework version (for example max generation length or dtype). Leave unchanged to use defaults
    Quantization Shown when the model repository provides quantized files, such as GGUF or AWQ
    Security Level Public: accessible without authentication; Private: requires authentication

    The create page estimates the VRAM needed for inference and compares it with the GPU Memory (GB) advertised on each specification:

    1. Weight VRAM ≈ parameter count (billions) × bytes per parameter (2 for BF16 / F16).
    2. Inference recommendation = weight VRAM × 1.5 (KV cache). If the scanned “weights + KV + activation” estimate is larger, the larger value is used.
    3. Specifications whose advertised VRAM is below the recommendation are marked Low Memory. You can still select them, but inference is more likely to OOM.

    Example: a ~27.78B BF16 model has about 55.56 GB of weights, so the inference recommendation is about 83 GB.

    Note

    The recommendation is for SKU selection only. It is not used for GPU scheduling or vGPU slicing. Administrators must fill in the advertised GPU Memory (GB) with the usable VRAM of the whole card or slice.

    View Instance List

    After creation, use the top navigation to open Model Inference → Dedicated Instances to view all created instances and their running status. You can also view them centrally in the dedicated instances section of Resource Management.

    Calling the Inference Service

    Once the instance is running, the platform provides:

    • Web Testing Interface: Test the model directly in your browser via conversation.
    • API Interface: OpenAI-compatible API for business code integration.

    For private instances, include an access token in the request header:

    curl https://<instance-address>/v1/chat/completions \
      -H "Authorization: Bearer <access-token>" \
      -H "Content-Type: application/json" \
      -d '{
        "model": "<model-name>",
        "messages": [{"role": "user", "content": "Hello"}]
      }'
