NV-Reason-CT processes 3D CT volumes natively (not slice-by-slice) and generates structured diagnostic reports with step-by-step chain-of-thought reasoning validated by NIH radiologists. It scores state-of-the-art on CT-RATE (Macro-F1 0.614).

Nemotron 3 Diarization is an open-weight speaker diarization model designed to determine "who spoke when" in real-world audio. It supports both streaming and offline inference and handles up to eight speakers.

▶ Hear it first. Natural turn-taking, barge-in and live tool calling.

Cosmos-H-Dreams is a real-time, action-conditioned generative surgical world model that lets a human operator or a learned surgical-robotics policy act inside a synthesized surgical scene and observe the interactions live.

NVIDIA-Ising-Calibration-1.5-31B-BF16 is a dense multimodal vision-language model built on Gemma 4 31B.

NVIDIA Cosmos™ is a world foundation model platform designed to accelerate the development of Physical AI by enabling machines to understand, simulate, and interact with the physical world across robotics, autonomous driving, and smart space environments, including industrial and factory-scale applications.

We're excited to introduce Nemotron-Labs-Audex-2B, a unified audio-text LLM with a similar recipe as Nemotron-Labs-Audex-30B-A3B. Audex-2B extends the vocabulary for discrete audio tokens used for speech and general audio outputs, as well as an audio encoder for speech and general audio inputs.

NVIDIA Cosmos3-Edge is a 4B-parameter omni-modal world model that generates text, images, video, and action commands from multimodal inputs. Its Mixture-of-Transformers architecture combines autoregressive decoding for text with diffusion-based denoising for other modalities. Optimized for physical AI, it serves robotics, autonomous vehicles, and smart space simulations.

NVIDIA Nemotron Parse 2.0 transforms document images into structured, machine-readable representations with text, layout classes, bounding boxes, and reading-order information.

Nemotron-Labs-3-Puzzle-75B-A9B is a deployment-optimized large language model developed by NVIDIA, derived from Nemotron-3-Super-120B-A12B.

NVIDIA's powerful open-weights MoE model: hybrid LatentMoE + MTP layers, 1M context, 550B/55B active. Free on OpenRouter. Focus: complex multi-agent workflows, code, math, science.

NVIDIA Nemotron 3.5 Content Safety is a compact 4B-parameter multimodal guardrail model from NVIDIA, fine-tuned from Google Gemma-3-4B. It moderates both inputs to and responses from LLMs and VLMs, accepting...

ArtiFixer is a few-step causal auto-regressive model that enhances and extends 3D reconstruction. The related source code provides implementations for training, evaluation, and inference, supporting various stages including bidirectional training, diffusion forcing, and Self-Forcing-style DMD distillation.

NVIDIA's small multimodal reasoning model: 30B MoE, only 3B active, text+image+audio input. Free on OpenRouter. Designed for on-device, 4x faster than its predecessor, reasoning ON/OFF mode.
