NVIDIA AI

Last-mile accuracy remains a challenge in physical AI, with training data bottlenecks and slow post-training iteration cycles slowing teams down. NVIDIA Cosmos 3 is the open frontier omni-model for physical AI — and now with NVIDIA TAO agentic skills, you can solve that last-mile accuracy challenge. This livestream shows how to post-train Cosmos 3 in a day, with just a few natural language prompts - taking Cosmos 3 Nano video question answering from 54.41% to 93.35% accuracy with AutoML. What You'll Learn: · Why post-train and which method to choose (LoRA vs. SFT) · How to run an end-to-end post-training pipeline for Cosmos 3 with a single prompt · How TAO AutoML eliminates manual hyperparameter tuning · How to deploy your post-trained model with NVIDIA NIM Have questions about how to post-train and deploy NVIDIA Cosmos 3?

Today we released Nemotron 3 Embed 8B and it reached #1 overall on RTEB 🏆 RTEB benchmarks retrieval accuracy across real-world tasks. Better retrieval gives agents more relevant context, helping improve response accuracy. Explore the models and results: https://lnkd.in/exvQVpuk

NVIDIA DeepStream 9.1 is here, with 13 agentic skills for building video analytics pipelines. Instead of manually building your vision AI pipeline from scratch, describe what you want in plain natural language. Use skills with a coding agent, like Claude Code or Codex, to easily handle setup, configuration, and execution. New skills include Multi-View 3D Tracking (MV3DT) for tracking objects across multiple cameras, and AutoMagicCalib for automatically calibrating a camera network. This release also brings NVIDIA JetPack 7.2 support for edge deployment on Jetson Orin and Thor. All open source on GitHub, check it out: https://nvda.ws/4vv0orS

Congrats Thinking Machines Lab on the new open model 🙌 Inkling was trained on NVIDIA GB300 NVL72 and the NVFP4 checkpoint is available today on Hugging Face: https://lnkd.in/ggPYgBDF Happy building!

Join Arm, the world leader in energy-efficient AI compute, for a local agent demo on the HP ZGX Nano AI Station, powered by DGX Spark. This live demo will showcase an NVIDIA NemoClaw agent running Qwen3-Coder entirely on-device. Attendees will watch the agent use the Arm MCP Server to autonomously migrate a legacy x86 application to Arm. See firsthand how the agent scans the code, ports its SSE intrinsics to NEON, builds natively on Arm, and verifies the final results—all without human intervention.

First stop in Japan: Build-a-Claw. 🇯🇵 Jensen made a surprise stop in the heart of Tokyo to meet with devs, give away some DGX Sparks, and see what they're building with open models.

Customizing open models doesn't have to mean managing your own GPU cluster. In this livestream, we walk through a complete hosted reinforcement learning run on Nemotron 3 Nano — from a cold start to a downloadable LoRA adapter — using Prime Intellect Lab. Local setup takes about five minutes. Prime Intellect handles the rest. The session follows the same three-step loop: get a baseline, train with RLVR, and reevaluate under identical conditions. You'll see how to configure and launch a LoRA RL job, read reward curves and rollouts to understand what the model actually learned, and deploy the adapter for inference. You can also apply the same workflow to Nemotron 3 Super and Ultra, and extend it to real software engineering tasks. What you'll learn: - How to install the Prime CLI, set up a Lab workspace, and run a baseline evaluation in minutes - How to configure and launch a hosted LoRA RL training job on Nemotron 3 Nano - How to read reward curves and rollout traces to distinguish learning from reward hacking - How to deploy a LoRA adapter and rerun evaluation to measure actual improvement How to apply this workflow to Nemotron 3 Super and Ultra, and scale to harder tasks Ready to start training your own open models? Bring your questions live.

Coding agents can now run RL experiments on open models like Nemotron end to end — handling setup, running multi-hour autoresearch campaigns, and dramatically improving model accuracy on tasks you define. NVIDIA verified agent skills make this practical on a single GPU: structured workflow instructions that keep an agent on-task, preserve memory across long runs, and drive the full experiment loop. This tutorial livestream shows you how, using NeMo RL and NeMo Gym. What you'll learn: How to set up NeMo RL on a GPU instance using a coding agent How to build a NeMo Gym environment and run a goal-driven autoresearch campaign How to use NVIDIA verified agent skills to maintain session state and structure the RL experiment loop How to implement an off-policy RL algorithm from a research paper with agent-led paper-to-code Automating RL research? Specializing open models like Nemotron for your own domain? Bring your questions — the team will answer them live.

🚦 The zero-shot model misses a visible traffic signal. After post-training Cosmos 3 Nano with LoRA, it correctly identifies the intersection, and overall WTS validation accuracy increases from 54.41% to 87.14%. 📈 With NVIDIA TAO AutoML, accuracy reaches 93.35%. All in under a day. Read the technical walkthrough → https://nvda.ws/4wHZqcP

We gave a coding agent a goal and a time budget: build a training environment and teach a vision model to count colored stars. Using autoresearch with NeMo RL, NeMo Gym, and reusable skills, the agent set up, trained and evaluated the model while the researcher steered the work. Qwen3-VL-2B went from 25% to 96.9% accuracy, and the agent even proposed the next experiment on its own. If you want to try it out for yourself, follow along here: https://nvda.ws/4aRUQQY
