### Restate TS

Source: https://docs.restate.dev/ai/patterns/competitive-racing

This code snippet demonstrates how to race multiple AI models concurrently using Restate TS. It starts two service calls, waits for the first one to complete, and cancels the other. The example includes installation, setup, and execution instructions.

```typescript
async function run(
      ctx: Context,
      { message }: { message: string },
    ): Promise<string> {
      // Start both service calls concurrently
      const slowCall = ctx.serviceClient(racingAgent).thinkLonger({ message });
      const slowResponse = slowCall.map((res) => ({ tag: "slow", res }));

      const fastCall = ctx.serviceClient(racingAgent).respondQuickly({ message });
      const fastResponse = fastCall.map((res) => ({ tag: "fast", res }));

      const pending = [slowResponse, fastResponse];

      // Wait for the first one to complete
      const { tag, res } = await RestatePromise.any(pending);

      if (tag === "fast") {
        console.log("Quick response won the race!");
        const slowInvocationId = await slowCall.invocationId;
        ctx.cancel(slowInvocationId);
      } else {
        console.log("Deep analysis won the race!");
        const quickInvocationId = await fastCall.invocationId;
        ctx.cancel(quickInvocationId);
      }

      return res ?? "LLM gave no response";
    }
```

```bash
restate-server
```

```bash
restate example typescript-restate-tour-of-agents && cd typescript-restate-tour-of-agents
npm install
```

```bash
export OPENAI_API_KEY=sk-...
```

```bash
npx tsx ./src/racing-agents.ts
```

```bash
restate deployments register http://localhost:9080 --force --yes # dev only: overrides previous registrations
```

```bash
curl localhost:8080/RacingAgent/run \
--json '{ 
    "message": "What is the best approach to learn machine learning?"
