Tesla's next-generation Optimus humanoid robot, referred to as Optimus Gen 3, has been previewed through new 3D design assets found in the Android version of Tesla’s mobile app. These assets, which include renders labeled “gen3” and images comparing Optimus Gen 2.5 and Gen 3, indicate significant design changes. The robot features a cleaner aesthetic with enclosed joints, a unified torso shell, thicker forearms, slimmer wrists, and redesigned legs that resemble integrated boots. The assets began appearing in app builds around August 27, 2026, with higher-resolution versions on September 5. Tesla initially planned to unveil Optimus Gen 3 by the end of Q1 2026, but this timeline was missed. Elon Musk later indicated that the reveal was postponed to mid-year for strategic reasons. Tesla has also started auditing suppliers in China for Gen 3 production, suggesting a potential reveal is approaching.
