NVIDIA Llama Nemotron Nano VLM Released on Hugging Face Hub
NVIDIA has released the Llama Nemotron Nano VLM on Hugging Face Hub, a compact vision-language model built on the Llama architecture. The model is part of NVIDIA's Nemotron family targeting efficient multimodal inference. This release makes the model accessible to the broader research and developer community through Hugging Face's model hosting infrastructure.
Nvidia Nemotron 3 Ultra: hybrid Mamba-transformer open-weights model targeting agentic workloads
Nvidia released Nemotron 3 Ultra, a 550B parameter (55B active) hybrid Mamba-transformer mixture-of-experts model with a 1M token context window, publishing weights, training data, and RL environments under an open license. The model ranks as the highest-scoring U.S. open-weights model on the Artificial Analysis Intelligence Index (47.7-48.2) and is approximately three times faster than comparable open-weights rivals, though it trails leading Chinese models like Kimi K2.6 and DeepSeek V4 Pro on intelligence benchmarks. Nvidia used a novel Multi-Teacher On-Policy Distillation approach with 10+ specialized teacher models and trained using NVFP4 quantization. The release is strategically motivated by Nvidia's interest in a healthy open-weights ecosystem that drives AI semiconductor adoption.
Nvidia releases Nemotron 3 Super 120B-A12B open-weights model with hybrid Mamba-2/MoE architecture
Nvidia released Nemotron 3 Super 120B-A12B, an open-weights LLM with a hybrid Mamba-2/transformer/MoE architecture that activates only 12B parameters per token and supports up to 1 million token context. The model claims the fastest inference speed in its size class at 442 tokens/second and leads open-weights models on PinchBench agentic task evaluation, outperforming larger models including Kimi K2.5 (1T parameters). Nvidia is releasing weights, training data, and recipes under a permissive commercial license, and plans a $26B five-year investment in open-weights models — framed partly as a strategic response to Chinese labs building capable open-weights models on non-Nvidia hardware.
The Open Evaluation Standard: Benchmarking NVIDIA Nemotron 3 Nano with NeMo Evaluator

Mistral NeMo: 12B Open-Weights Model with 128k Context, Built with NVIDIA
Mistral AI and NVIDIA jointly release Mistral NeMo, a 12B parameter model under Apache 2.0 license featuring a 128k token context window and a new tokenizer called Tekken based on Tiktoken. The model is designed as a drop-in replacement for Mistral 7B, supports multilingual applications across 11+ languages, and was trained with quantization awareness enabling FP8 inference without performance loss. Benchmark comparisons show competitive performance against Gemma 2 9B and Llama 3 8B. Weights are available on HuggingFace and the model is also packaged as an NVIDIA NIM inference microservice.
Data Points: NemoClaw enterprise stack, GPT-5.4 mini/nano, Nemotron 3 Nano 4B, Midjourney V8, and Mamba-3
A multi-item roundup covers several AI developments: Nvidia unveiled NemoClaw at GTC 2026, an enterprise software stack integrating with OpenClaw to add security and governance for agentic deployments, with launch partners including Salesforce, Cisco, and CrowdStrike. OpenAI released GPT-5.4 mini and nano, smaller variants optimized for speed with benchmark results on SWE-Bench Pro and OSWorld-Verified, priced at $0.75 and $0.20 per million input tokens respectively. Nvidia also released Nemotron 3 Nano 4B, a hybrid Mamba-Transformer 4B parameter on-device model. Additional items cover Midjourney V8 alpha (5x faster, diffusion-only) and Mamba-3, a 1.5B state space model from CMU and Together.AI with improved accuracy over Mamba-2.
NVIDIA NeMo Gym: framework for evaluating and improving models and agents using environments
NVIDIA's NeMo team has published a Python library called NeMo Gym on GitHub, designed to evaluate and improve models and agents through environment-based interaction.
