You can now access Arcee AI's latest model Trinity Mini via Vercel's [AI Gateway](https://vercel.com/ai-gateway) with no other provider accounts required. Trinity Mini is an open weight MoE reasoning model with 26B parameters (3B active) trained end-to-end in the U.S.

To use Trinity Mini, set `model` to `arcee-ai/trinity-mini` in the [AI SDK](https://ai-sdk.dev/).

```tsx
import { streamText } from 'ai';
const result = streamText({
  model: 'arcee-ai/trinity-mini',
  prompt:
  `Generate a full reasoning chain that reconstructs how an unknown machine
   operates solely from its final outputs, inferring internal mechanisms,
   intermediate states, and causal links step by step.`,
});
```

AI Gateway provides a unified API for calling models, tracking usage and cost, and configuring retries, failover, and performance optimizations for higher-than-provider uptime. It includes built-in [observability](https://vercel.com/docs/ai-gateway/observability), [Bring Your Own Key support](https://vercel.com/docs/ai-gateway/byok), and intelligent [provider routing](https://vercel.com/docs/ai-gateway/provider-options) with automatic retries.

Read the [docs](https://vercel.com/docs/ai-gateway), view the [AI Gateway model leaderboard](https://vercel.com/ai-gateway/leaderboards), or use the model directly in our [model playground](https://vercel.com/ai-gateway/models/trinity-mini).
