NVIDIA

NVIDIA provides an OpenAI-compatible API at https://integrate.api.nvidia.com/v1 for open models for free. Authenticate with an API key from build.nvidia.com.

Getting started

Get your API key

Create an API key at build.nvidia.com.

Export the key and run onboarding

export NVIDIA_API_KEY="nvapi-..."
fluffbuzz onboard --auth-choice skip

Set an NVIDIA model

fluffbuzz models set nvidia/nvidia/nemotron-3-super-120b-a12b

If you pass --token instead of the env var, the value lands in shell history and ps output. Prefer the NVIDIA_API_KEY environment variable when possible.

Config example

{
  env: { NVIDIA_API_KEY: "nvapi-..." },
  models: {
    providers: {
      nvidia: {
        baseUrl: "https://integrate.api.nvidia.com/v1",
        api: "openai-completions",
      },
    },
  },
  agents: {
    defaults: {
      model: { primary: "nvidia/nvidia/nemotron-3-super-120b-a12b" },
    },
  },
}

Built-in catalog

Model ref	Name	Context	Max output
`nvidia/nvidia/nemotron-3-super-120b-a12b`	NVIDIA Nemotron 3 Super 120B	262,144	8,192

Advanced configuration

Auto-enable behavior

The provider auto-enables when the NVIDIA_API_KEY environment variable is set. No explicit provider config is required beyond the key.

Catalog and pricing

The bundled catalog is static. Costs default to 0 in source since NVIDIA currently offers free API access for the listed models.

OpenAI-compatible endpoint

NVIDIA uses the standard /v1 completions endpoint. Any OpenAI-compatible tooling should work out of the box with the NVIDIA base URL.

NVIDIA models are currently free to use. Check build.nvidia.com for the latest availability and rate-limit details.
