Tesla's Optimus gen 3 humanoid robot leaked via app, reveals design shifts and production timeline

A leaked 3D model of Tesla's Optimus Gen 3 humanoid robot was discovered in the company's Android app, offering a glimpse into its evolving design. The model, found by Tesla enthusiast @WholeMars, shows a more streamlined and industrial look compared to the Gen 2.5 prototype. Key changes include a sealed joint design, a black-and-champagne gold color scheme, and a more complete hand with 22 degrees of freedom. Tesla's focus on mass production is evident, with plans to scale up production at the Gigafactory Texas to 1 million units annually by year-end. The company has delayed the public debut of Gen 3, with a potential release in late 2026 or early 2027. Meanwhile, Tesla is preparing for the Roadster launch on October 1, 2026, and is accelerating production readiness at the Fremont factory.
