Web search on Azure OpenAI Responses API

[jmartinezb3]

What happened?

Web search doesn't work with GPT-4o, o3, or o4-mini, none of them.

It is something I have to do server-side?

My actual Azure OpenAI config:

endpoints:
  azureOpenAI:
    # Endpoint-level configuration
    titleModel: "gpt-4o-mini"
    plugins: true
    assistants: true
    groups:
    # Group-level configuration
    - group: "azure-OpenAI-chat"
      apiKey: "${EASTUS2_API_KEY}"
      instanceName: "${INSTANCE_NAME}"
      assistants: true
      version: "preview"
      # Model-level configuration
      models:
        gpt-4.1:
          deploymentName: gpt-4.1
        gpt-4o:
          deploymentName: gpt-4o_2024-11-20
        gpt-4o-mini:
          deploymentName: gpt-4o-mini_2024-07-18
        o3:
          deploymentName: o3
        o3-pro:
          deploymentName: o3-pro
        o4-mini:
          deploymentName: o4-mini
