Qwen/Qwen3-VL-8B-Instruct-FP8 powered by vLLM

Chat Completions API

Send Request

You can use cURL or any REST Client to send a request to the Azure ML endpoint with your Azure ML token.

curl <AZUREML_ENDPOINT_URL> \\
    -X POST \\
    -H "Authorization: Bearer <AZUREML_TOKEN>" \\
    -H "Content-Type: application/json" \\
    -d '{"model":"Qwen/Qwen3-VL-8B-Instruct-FP8","messages":[{"role":"user","content":"What is Deep Learning?"}]}'

Supported Parameters

The following are the only mandatory parameters to send in the HTTP POST request to v1/chat/completions.

model (string): Model ID used to generate the response, in this case since only a single model is deployed within the same endpoint you can either set it to Qwen/Qwen3-VL-8B-Instruct-FP8 or leave it blank instead.
messages (array): A list of messages comprising the conversation so far. Depending on the model you use, different message types (modalities) are supported, like text, images, and audio.

The rest of the parameters are optional, and since this model is powered by vLLM with an OpenAI compatible interface on top for the Chat Completions API for text generation, then the I/O interfaces for both generation and streaming are the same as in OpenAI Chat Completions API. You can find the whole specification of the allowed parameters in the OpenAI Chat Completion API Specification , or alternatively in the endpoint /openapi.json for the current Azure ML Endpoint.
