Hi,

Any update on this? Also do you currently support vercel/ai 4.1.x?

Would love to know if this issue is on the schedule to be fixed soon. I also note Vercel has just released AI SDK 4.2.

Hey @blackge & @davidcrouch - sorry for the wait! Please refer to the below code snippet on how to use streamText():

import { streamText } from 'ai';
import { openai } from '@ai-sdk/openai';
import { VercelAIToolSet } from "composio-core";

const toolset = new VercelAIToolSet({ apiKey: "<composio-api-key>" });
const tools = await toolset.getTools({ actions: ["GMAIL_FETCH_EMAILS"] });

async function main() {
    const prompt = "Fetch the last email from my gmail account & summarise it";

    const { textStream } = streamText({
        model: openai('gpt-4o'),
        system: 'You are a helpful assistant. Use the provided tools when needed.',
        tools,
        prompt,
        maxSteps: 5
    });
    for await (const textPart of textStream) {
        process.stdout.write(textPart);
    }
}

main().catch(console.error);
