systemInstruction: SystemInstruction,
text: TextPart,
init: GenerateContentRequest.Builder.() -> Unit
): GenerateContentRequest
Helper method to construct a GenerateContentRequest in a DSL-like manner.
Example Usage:
// Generation Request with system instruction and text:
generateContentRequest(SystemInstruction("You are a helpful assistant."), TextPart("Hello World")) {
