-If an agent includes [`ComputerTool`][agents.tool.ComputerTool], the effective model on the actual Responses request determines which computer-tool payload the SDK sends.

-Prompt-managed calls are the main exception.

To keep the GA path in that flow, either make `model="gpt-5.4"` explicit on the request or force the GA selector with `ModelSettings(tool_choice="computer")` or `ModelSettings(tool_choice="computer_use")`.

 Transport selection happens when the SDK resolves a model name into a model instance. If you pass a concrete [`Model`][agents.models.interface.Model] object, its transport is already fixed: [`OpenAIResponsesWSModel`][agents.models.openai_responses.OpenAIResponsesWSModel] uses websocket, [`OpenAIResponsesModel`][agents.models.openai_responses.OpenAIResponsesModel] uses HTTP, and [`OpenAIChatCompletionsModel`][agents.models.openai_chatcompletions.OpenAIChatCompletionsModel] stays on Chat Completions.

 This distinction matters when `ComputerTool` is backed by a [`ComputerProvider`][agents.tool.ComputerProvider] factory.
