# Nvidia releases 4B-parameter on-device world model for robots

*2026-07-21 · Source: [MarkTechPost](https://www.marktechpost.com/2026/07/21/nvidia-releases-cosmos-3-edge-a-4b-parameter-open-world-model-that-reasons-and-generates-robot-actions-on-device/)*

Nvidia released Cosmos 3 Edge, a 4-billion-parameter world model built to run on-device for robots and vision AI agents. It helps them reason about their surroundings and generate robot actions locally, joining the Cosmos 3 Nano (16B) and Cosmos 3 Super (64B) models Nvidia shipped in May at GTC Taipei.

**Why it matters:** Shrinking world models to edge-deployable sizes matters for robotics because it cuts the latency and connectivity dependence of cloud inference, a prerequisite for real-time physical action. It also extends Nvidia's strategy of spanning a full size range, from 4B to 64B, so robot makers can trade off capability against power and cost within the same model family.

**Topics:** research, robotics
