Overview
Join the Cosmos™ Cookoff, a hands-on physical AI challenge for developers, researchers, and system builders in robotics, autonomous vehicles, and vision AI. Build innovative solutions with Cosmos Reason 2, a leaderboard-topping, open reasoning vision language model that helps AI agents and autonomous systems see, understand, and act in the physical world like humans.
Why Participate?
This is an opportunity to level up your skills with cutting-edge physical AI models, build a project to solve a real-world problem, connect with experts, and learn alongside a community of physical AI enthusiasts. It’s your chance to show the world what’s possible with Cosmos.
The Challenge
Build something great with Cosmos Reason 2—post-train for a specialized reasoning model, a data curation tool, a robot brain that understands a new domain, or a video analytics agent.
Get creative with Cosmos Reason. You can use it standalone or mix in other open models to bring your vision to life.
Access NVIDIA experts, who will provide guidance, feedback, and technical help through office hours and our Discord channel to ensure you make the most of Cosmos Reason.
Note: Cosmos Reason is purpose-built for physical AI. This challenge does not cover generative media, art, gaming, or content creation projects.
Who Should Participate
Developers and researchers building robotics, autonomous vehicles, and vision AI pipelines
Teams (1-4 members)
Those looking to experiment, evaluate, and benchmark physical AI workflows in a safe, supported environment
Additional Tools From the Cosmos Cookbook
Kick off with Cosmos Cookbook recipes, but you can also adapt, extend, or innovate across robotics, autonomy, simulation, transportation, or more. We recommend the following recipes:
Egocentric Social and Physical Reasoning—Test and evaluate robot-human social and spatial interactions with reasoning.
Post-Training Cosmos Reason (Intelligent Transportation)—Learn how to post-train Cosmos Reason using a supervised fine-tuning technique with an example transportation dataset to better understand traffic scenarios.
Physical Plausibility Prediction—Synthetic data generation is a game-changer, but not all of the outputs are usable. This recipe shows how to evaluate the physical plausibility of synthetically generated videos.
Build a Video Analytics AI Agent—Unlock the power of agentic AI to understand, reason, and act on your live video streams or stored files. Use the NVIDIA Blueprint for video search and summarization, and start getting insights.
