Nvidia's New Open Weights Nemotron 3 Super Combines Three Different Architectures to Beat Gpt-Oss and Qwen in Throughput

Nemotron 3 Super boosts throughput by up to 2.2x over competitors with a triple hybrid architecture optimized for Nvidia Blackwell GPUs to reduce enterprise AI costs.

  • On Wednesday, Nvidia launched Nemotron 3 Super, a 120-billion-parameter model with a 1-million-token context window, publishing weights on Hugging Face and listing it on build.nvidia.com, Perplexity, and OpenRouter.
  • Kari Briski says companies face context explosion, prompting the new model, which Nvidia frames as reducing the enterprise 'thinking tax' by merging architectures for agentic workflows.
  • Technically, the model combines a Hybrid Mamba-Transformer backbone that interleaves Mamba-2 layers with Transformer attention, pretrained in NVFP4 for Blackwell GPUs.
  • Availability spans Nvidia's site, Hugging Face, and major cloud platforms, with enterprises like CodeRabbit and Greptile integrating Nemotron 3 Super as an Nvidia NIM microservice on-prem and across clouds including Google Cloud and Oracle, with AWS and Azure coming shortly.
  • Benchmarks report up to 2.2x higher throughput versus gpt-oss-120B and 7.5x versus Qwen3.5-122B, with Artificial Analysis measuring 478 output tokens per second, while Nvidia says the Nvidia Open Model License permits commercial use with termination triggers.
