Nemotron 3 Ultra from Nvidia is now available on Vercel AI Gateway.

Nemotron 3 Ultra is an open Mixture-of-Experts reasoning model built for orchestrating long-running agent workflows, with a 1M token context window. The model targets multi-turn agent workflows: planning, tool use, sub-agent delegation, and error recovery. Throughput reaches up to 350 tokens per second, with up to 30% lower cost on agentic tasks.

To use Nemotron 3 Ultra, set model to nvidia/nemotron-3-ultra-550b-a55b in the AI SDK.

import { streamText } from 'ai';
const result = streamText({
  model: 'nvidia/nemotron-3-ultra-550b-a55b',
  prompt: 'Plan and run a multi-step research task and synthesize a report.',
});
