Temporal Vercel AI SDK integration

Release stage: Generally Available.

Run Vercel AI SDK agents as durable Temporal Workflows. Model and MCP requests execute as Activities so Temporal can record results, retry failures and replay completed calls.

// Worker setup
import { AiSdkPlugin } from '@temporalio/vercel-ai-sdk';
import { openai } from '@ai-sdk/openai';

const plugins = [new AiSdkPlugin({ modelProvider: openai })];

// Workflow code
import { generateText } from 'ai';
import { temporalProvider } from '@temporalio/vercel-ai-sdk/workflow';

export async function answer(prompt: string): Promise<string> {
  const result = await generateText({
    model: temporalProvider.languageModel('gpt-4o-mini'),
    prompt,
  });
  return result.text;
}

Register plugins with the Temporal Worker. Provider credentials belong in the Worker environment. See the integration guide for model, tool, streaming and MCP configuration. That guide currently uses the SDK-owned @temporalio/ai-sdk name; this repository owns the new @temporalio/vercel-ai-sdk coordinate.

Development and migration details are in typescript/README.md.
