Urgent please: Custom Avatar Sample Code: How to set temperature?

It is VMS 170

Hi folks

Have a look at https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/js/browser/avatar

There's a place where we can call the OpenAI endpoint with a prompt. We'd like to also send a temperature for this. Where do we set it? can't see it neither in the javascript source files

Any ideas will be very much appreciated!

Thanks!

@Manas Mohanty : you are one hell of a resourceful guy who has helped us in the past, on this topic... please see if you can look at this.

Hi It is VMS

To accurately set the temperature parameter when calling the OpenAI endpoint in the https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/samples/js/browser/avatar avatar sample, you’ll need to modify the JavaScript source code where the OpenAI API request is constructed.

Although the UI allows you to configure the endpoint, API key, deployment name, and system prompt, it does not expose a field for temperature. This means the value must be added manually in the code that sends the request to the Azure OpenAI service.

Look for the file where the OpenAI fetch() or axios.post() request is made. This is typically in a file like chat.jsand then add the temperature field to the JSON body of the request.

Here is the example

const response = await fetch("https://<your-endpoint>.openai.azure.com/openai/deployments/<deployment-id>/chat/completions?api-version=2023-03-15-preview", { method: "POST", headers: { "Content-Type": "application/json", "api-key": "<your-api-key>" }, body: JSON.stringify({ messages: [ { role: "system", content: "You are an AI assistant..." }, { role: "user", content: "Your prompt here" } ], temperature: 0.7, // <-- Add this line max_tokens: 1000 })

If the code uses a wrapper or helper function to build the request, ensure temperature is passed through all relevant layers.

Hope it helps!

Thank you

Hi It is VMS

Yes, Agreed with Shivaprasad's inputs

Found the code snippet in chat.js

   body = JSON.stringify({
            dataSources: dataSources,
            messages: messages,
            stream: true
        })
    }

Can be replaced with

let body = JSON.stringify({
    messages: messages,
    stream: true,
    temperature: 0.7 // or any value between 0 and 2
})

let url = "{AOAIEndpoint}/openai/deployments/{AOAIDeployment}/chat/completions?api-version=2023-06-01-preview".replace("{AOAIEndpoint}", azureOpenAIEndpoint).replace("{AOAIDeployment}", azureOpenAIDeploymentName)
    let body = JSON.stringify({
        messages: messages,
        stream: true
    })

    if (dataSources.length > 0) {
        url = "{AOAIEndpoint}/openai/deployments/{AOAIDeployment}/extensions/chat/completions?api-version=2023-06-01-preview".replace("{AOAIEndpoint}", azureOpenAIEndpoint).replace("{AOAIDeployment}", azureOpenAIDeploymentName)
        body = JSON.stringify({
            dataSources: dataSources,
            messages: messages,
            stream: true
        })
    }

    let assistantReply = ''
    let toolContent = ''
    let spokenSentence = ''
    let displaySentence = ''

    fetch(url, {
        method: 'POST',
        headers: {
            'api-key': azureOpenAIApiKey,
            'Content-Type': 'application/json'
        },
        body: body
    })

Hope it helps.

Thank you.
