Nemotron 3 Ultra is a paid model, though some providers may offer trial credits or limited free tiers for evaluation. Check NVIDIA's website for current free tier availability and promotional offers.

Nemotron 3 Ultra supports a 1,000K token context window (1,000,000 tokens total). That translates to roughly 750,000 words in a single prompt. This is large enough to process entire codebases, research papers, or long conversation histories in one shot.

Nemotron 3 Ultra can generate up to 16K output tokens (16,384 tokens) per response. That is roughly 12,288 words. This is enough for generating complete code files, detailed reports, or long-form content in a single response.

Nemotron 3 Ultra supports function/tool calling, structured JSON output, extended reasoning/chain-of-thought, streaming responses. Function calling lets you integrate it with external APIs and tools programmatically. These capabilities determine which workflows and integrations the model can handle natively.

Yes, Nemotron 3 Ultra is an open-source model. You can download the weights, run it locally, fine-tune it for your use case, or deploy it on your own infrastructure. Many cloud providers also offer hosted versions if you prefer not to manage the infrastructure yourself. Self-hosting gives you full control over data privacy and eliminates per-token API costs.

Nemotron 3 Ultra was developed by NVIDIA. It was released on June 4, 2026. You can access it through NVIDIA's API or download the model weights directly. Check our provider page for all models from NVIDIA and how they compare against each other.

Pick Nemotron 3 Ultra when you need a budget-friendly option for high-volume, simpler tasks where you prioritize cost over peak performance. If your task is straightforward text completion or classification, a cheaper model might give you 90% of the quality at a fraction of the price. Run a quick benchmark on your actual use case before committing.

You can access Nemotron 3 Ultra through NVIDIA's API using standard HTTP requests or their official SDK. Most providers support OpenAI-compatible endpoints, so switching between models often requires changing just the model name in your API call. Streaming is supported for real-time token-by-token output. For production use, implement proper error handling, rate limiting, and cost monitoring.
