NVIDIA Nemotron-3-Super-120B-A12B

One-line: NVIDIA’s flagship open reasoning/chat model — a hybrid LatentMoE (Mamba-2 + MoE + MTP) with 12B active params, up to 1M context, and top-tier agentic coding scores.

⚠ Not a new drop this window. Released March 11, 2026; the lastModified bump on 2026-08-24 is a card/benchmark-table update, not new weights. Surfacing here because it qualifies as “trending” (high downloads + recent activity). ⚠ Large: 120B total — needs multi-GPU/workstation; consumer-local requires heavy quantization.

Efficiency

  • Active params: 12B active / 120B total
  • Context length: 1,048,576 tokens (default 256k in HF config; 1M requires VLLM_ALLOW_LONG_MAX_MODEL_LEN=1)
  • VRAM (fp16 rough): ~240 GB at fp16 (120B × 2 bytes) — ⚠ not consumer-friendly; quantization required to run locally

What makes it notable

Nemotron-3-Super is a strong general-purpose coding/agentic model: 60.47 SWE-bench Verified (OpenHands harness), 81.19 LiveCodeBench, and a τ-Bench V2 average of 61.15 plus Terminal Bench/BrowseComp — genuine multi-agent credentials, not just an MMLU card. Its LatentMoE (Mamba-2 + MoE + attention hybrid with MTP) routes through a smaller latent space for better accuracy-per-byte, and it supports up to 1M context for long agent trajectories. Crucially it is fully open — weights, datasets, and recipes under the NVIDIA Nemotron Open Model License, and the card states it is “ready for commercial use.” The catch for the “run it locally” user is the 120B total footprint. Positioned against Qwen3.5-122B-A10B (~66 SWE-bench) and GPT-OSS-120B (~42 SWE-bench): it splits the difference, beating the open-weights baseline substantially.
