See more AI Examples

This is the simplest example of using Chilkat with Azure AI Foundry. VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

Dim ai As New Chilkat.Ai

' For Azure AI Foundry we use "custom".
ai.Provider = "custom"

' The base URL format for the Chat Completions API when using the cognitiveservices.azure.com domain is:
' https://{resource-name}.cognitiveservices.azure.com/openai/deployments/{deployment-id}/chat/completions?api-version={api-version}

' The string "{deployment}" in the base URL is dynamically replaced with the selected AI model each time a request is sent.
' In this case, the chosen model (below) is "gpt-4o".  After substitution the base URL becomes: 
' https://chilkat.cognitiveservices.azure.com/openai/deployments/gpt-4o/chat/completions?api-version=2025-01-01-preview

' In this example, our resource name is "chilkat", and the api-version is "2025-01-01-preview"
ai.BaseUrl = "https://chilkat.cognitiveservices.azure.com/openai/deployments/{deployment}/chat/completions?api-version=2025-01-01-preview"
ai.ApiSpec = "ChatCompletions"

' Use your provider's API key.
ai.ApiKey = "MY_API_KEY"

' Choose a model.
ai.Model = "gpt-4o"

' Add a text input.
ai.InputAddText("Say Hello.")

' Ask the AI for text output.
success = ai.Ask("text")
If (success = False) Then
    Debug.WriteLine(ai.LastErrorText)
    Exit Sub
End If


' Get the text response.
Dim sbResponse As New Chilkat.StringBuilder
ai.GetOutputTextSb(sbResponse)
Debug.WriteLine(sbResponse.GetAsString())

' Sample output:
' Hello! How can I assist you today?
