Nemotron 3.5 Lightning now available on AI Gateway for free

Nemotron 3.5 Lightning is now available for free on AI Gateway, served by NVIDIA.

The open-weight reasoning and chat model supports long-running agents, subagents, chatbots, and retrieval-augmented generation (RAG). It has a 1 million-token context window, supports tool calling and structured outputs, and uses 3 billion of its 30 billion parameters per token.

Note: The provider may retain prompts for model improvement.

Use nvidia/nemotron-3.5-lightning-free as the model ID:

1
import { streamText } from 'ai';
2

3
const result = streamText({
4
  model: 'nvidia/nemotron-3.5-lightning-free',
5
  prompt: 'Write a TypeScript function that retries a failed fetch with exponential backoff.',
6
});

To use it in Claude Code, Codex, Cursor, and more, install the latest Edgenivo CLI and run setup:

npx vercel ai-gateway setup

Then select nvidia/nemotron-3.5-lightning-free in the agent. See the coding agents guide for details.
