Nemotron 3 Super 120B A12B

• Type: Generation
• Capabilities: reasoning

Overview

NVIDIA Nemotron 3 Super 120B A12B NVFP4 is an open hybrid Mamba-Transformer LatentMoE model with 120 billion total parameters and 12 billion active parameters, built for agentic reasoning workloads such as coding, planning, tool use, and long-context tasks. It sits in the same capability tier as Qwen3.5-122B non-reasoning and ahead of GPT-OSS-120B, while also delivering higher throughput.

---

In line with NVIDIA's guidance, we use temperature=1.0 and top_p=0.95 across all tasks and serving backends, including reasoning, tool calling, and general chat.

---

To enable reasoning, pass extra_body={"chat_template_kwargs": {"enable_thinking": true}}. For a more concise reasoning mode that uses significantly fewer reasoning tokens than full thinking mode, add "low_effort": true to the same payload.
