Providers
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. OpenClaw
defaults the NVIDIA provider to Nemotron 3 Ultra, NVIDIA's 550B total / 55B
active reasoning model for long-context agentic work.
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-..."openclaw onboard --auth-choice nvidia-api-keySet an NVIDIA model
openclaw models set nvidia/nvidia/nemotron-3-ultra-550b-a55bFor non-interactive setup, you can also pass the key directly:
openclaw onboard --auth-choice nvidia-api-key --nvidia-api-key "nvapi-..."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-ultra-550b-a55b" }, }, },}Featured catalog
When an NVIDIA API key is configured, OpenClaw setup and model-selection paths
try NVIDIA's public featured-model catalog from
https://assets.ngc.nvidia.com/products/api-catalog/featured-models.json and
caches the ranked result for 24 hours. New featured models from build.nvidia.com
therefore appear in setup and model-selection surfaces without waiting for an
OpenClaw release. When the live feed is available, the first returned model is
the default option shown during NVIDIA setup.
The fetch uses a fixed HTTPS host policy for assets.ngc.nvidia.com. If no
NVIDIA API key is configured, or if that public catalog is unavailable or
malformed, OpenClaw falls back to the bundled catalog and bundled default below.
Nemotron 3 Ultra
Nemotron 3 Ultra is the default NVIDIA model in OpenClaw. NVIDIA's build page for
nvidia/nemotron-3-ultra-550b-a55b
lists it as an available free endpoint with a 1M-token context specification.
The bundled catalog records a 16,384-token max output to match NVIDIA's current
OpenAI-compatible sample request for the hosted endpoint.
Use Ultra for the highest-capability NVIDIA default. Keep Super selected when
you want the smaller Nemotron 3 option, or choose one of the third-party models
hosted in NVIDIA's catalog when their context, latency, or behavior fits better.
The bundled Ultra row sends chat_template_kwargs.enable_thinking: false and
force_nonempty_content: true by default so normal chat output stays in the
visible answer instead of exposing reasoning text.

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
OpenClaw prefers NVIDIA's public featured-model catalog when NVIDIA auth is
configured and caches it for 24 hours. The bundled fallback catalog is static
and keeps deprecated shipped refs for upgrade compatibility. 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.
Nemotron 3 Ultra reasoning params
NVIDIA's Ultra sample request uses chat_template_kwargs.enable_thinking
and reasoning_budget for reasoning output. OpenClaw's bundled Ultra row
disables template thinking by default for normal chat use. If you need to
opt into NVIDIA reasoning output or force other NVIDIA-specific request
fields, set per-model params and keep provider-specific overrides scoped to
the NVIDIA model:
{ agents: { defaults: { models: { "nvidia/nvidia/nemotron-3-ultra-550b-a55b": { params: { chat_template_kwargs: { enable_thinking: true }, extra_body: { reasoning_budget: 16384 }, }, }, }, }, },}params.extra_body is the final OpenAI-compatible request-body override, so
use it only for fields NVIDIA documents for the selected endpoint.
Slow custom provider responses
Some NVIDIA-hosted custom models can take longer than the default model idle watchdog before they emit a first response chunk. For custom NVIDIA provider entries, raise the provider timeout instead of raising the whole agent runtime timeout:
{ models: { providers: { "custom-integrate-api-nvidia-com": { baseUrl: "https://integrate.api.nvidia.com/v1", api: "openai-completions", apiKey: "NVIDIA_API_KEY", timeoutSeconds: 300, }, }, }, agents: { defaults: { models: { "custom-integrate-api-nvidia-com/meta/llama-3.1-70b-instruct": { params: { thinking: "off" }, }, }, }, },}
