Only present when `model` is present in the request.
`model` here is normalized to have project number.

For example:
If the `model` requested in TranslationTextRequest is
`projects/{project-id}/locations/{location-id}/models/general/nmt` then
`model` here would be normalized to
`projects/{project-number}/locations/{location-id}/models/general/nmt`.

<code>string model = 2;</code>

@param value The bytes for model to set.
@return This builder for chaining.
