NVIDIA is ramping up its support for open-source AI by releasing a fresh batch of models, datasets, and tools aimed at both digital and physical applications, giving researchers across disciplines powerful new resources to push boundaries.
During the NeurIPS conference, a premier gathering for AI experts, the company is spotlighting advancements like Alpamayo-R1, billed as the first large-scale open model that combines vision, language, and action reasoning specifically for autonomous vehicle development. On the digital side, NVIDIA is rolling out tools for speech processing and ensuring AI safety.
The company’s researchers are contributing more than 70 papers, presentations, and sessions at the event, covering topics from enhanced AI decision-making to breakthroughs in healthcare and self-driving tech.
This push underscores NVIDIA’s dedication to open collaboration, which earned high marks in a recent evaluation by Artificial Analysis, an independent assessor of AI openness. Their Nemotron series of foundational models scored top marks for flexible licensing, clear data practices, and detailed technical documentation.
Alpamayo-R1 stands out for weaving logical step-by-step thinking into vehicle navigation, a key step toward safer self-driving systems capable of handling level 4 operations in tricky urban environments. Earlier models often faltered in unpredictable spots, like crowded crosswalks or unexpected roadblocks, but this one mimics human intuition by analyzing situations piece by piece and weighing options based on real-time context.
For instance, in a busy area with cyclists nearby, the model could process sensor inputs, explain its choices, and adjust its path to avoid hazards like erratic pedestrians or blocked lanes.
Built on NVIDIA’s Cosmos Reason foundation, Alpamayo-R1 allows academics to tweak it for experiments in areas like performance testing or prototype building, as long as it is not for profit. Fine-tuning with reinforcement learning has notably boosted its problem-solving skills over the base version.
Soon, developers can access Alpamayo-R1 via GitHub and Hugging Face, along with select training and testing data from NVIDIA’s Physical AI Open Datasets collection. The company is also sharing AlpaSim, an open toolset for assessing the model’s performance. For deeper insights, check out the Alpamayo-R1 research publication.
To help build on these foundations, NVIDIA has updated the Cosmos Cookbook with practical guides for adapting Cosmos models, from quick setups to full data pipelines involving simulated environments and assessments. The platform’s versatility shines in recent projects, such as LidarGen, which creates realistic sensor data for vehicle simulations; Omniverse NuRec Fixer, which cleans up visual glitches in reconstructed scenes for robotics; Cosmos Policy, which adapts video models into reliable robot instructions; and ProtoMotions3, a simulator for training digital humans and robots using generated real-world scenes.
These efforts integrate with tools like Isaac Lab and Isaac Sim for policy development, feeding into advanced robotics models such as GR00T N. Industry players are already using Cosmos for innovations, including Voxel51’s data recipes, and applications from firms like 1X, Figure AI, Foretellix, Gatik, Oxa, PlusAI, and X-Humanoid. Even academic teams at ETH Zurich are using it for lifelike 3D environments, as detailed in a upcoming NeurIPS paper.
Shifting to digital tools, NVIDIA is enhancing its Nemotron lineup with speech-focused models like MultiTalker Parakeet, which handles real-time transcription of group conversations even when voices overlap, and Sortformer, a top performer in separating speakers on the fly. For safety, there’s Nemotron Content Safety Reasoning, which applies tailored rules across various content types, paired with the Nemotron Safety Audio Dataset to train detectors for risky audio alongside text.
Complementing these are NeMo Gym, a library streamlining reinforcement learning setups for language models with prebuilt scenarios, and the newly open-sourced NeMo Data Designer Library under Apache 2.0, which streamlines creating and verifying custom synthetic data for specialized AI tuning.
Companies like CrowdStrike, Palantir, and ServiceNow are tapping Nemotron and NeMo to craft secure, task-oriented AI agents. Conference-goers can dive into these at the Nemotron Summit today from 4 to 8 p.m. PT, featuring a keynote from NVIDIA’s Bryan Catanzaro, vice president of applied deep learning research.
NVIDIA’s extensive NeurIPS lineup includes standout papers advancing natural language processing, with the full schedule available through the conference site, running until December 7 in San Diego.
