You can do this with includeThoughts: true in providerOptions.

Example

import { convertToCoreMessages, streamText, UIMessage } from "ai";
import { GoogleGenerativeAIProviderOptions, google } from "@ai-sdk/google";

export async function POST(request: Request) {
  const { messages }: { messages: UIMessage[]; selectedModel: modelID } =
    await request.json();

  const result = streamText({
    model: google("gemini-2.5-pro-preview-05-06"),
    messages: convertToCoreMessages(messages),
    providerOptions: {
      google: {
        includeThoughts: true,
      } satisfies GoogleGenerativeAIProviderOptions,
    },
  });

  return result.toDataStreamResponse({
    sendReasoning: true,
  });
}
