Elon Musk previously said Optimus will be central to Tesla's future as it expands from cars to AI and robotics.

The video, shared by Salesforce CEO Marc Benioff, shows the next-gen Optimus in new, gold attire, with several new visual details including more human-like hands. More importantly, Optimus now features Grok's voice mode, meaning it can understand user queries and answer them with spoken replies.

Yet that's exactly what Musk said about Tesla 's ( TSLA 3.59%) own "Master Plan Part 4," a day after it was unveiled on his social media site X. Responding to criticism of the plan, he admitted in a Tuesday post, "Fair enough. Will add more specifics."

Optimus has morphed from a speculative experiment into Tesla’s defining strategic centerpiece. Musk envisions deploying “thousands” of robots in factories by year-end, with production ramping to 1 million units annually by 2030, and estimates the value of each robot to be between $20,000 and $30,000.

The Optimus team has shifted away from motion capture suits and virtual reality headsets and plans to prioritize a vision-only approach.

With the exception of the struggling Cybertruck, Tesla hasn’t released an entirely new electric car in five years. Musk has indicated that he wants Tesla to primarily focus on building robotaxis and robots.

Elon Musk doubled down on his robotics vision, predicting that Optimus will eventually represent approximately 80% of Tesla's total value.

Tesla's board has proposed an unprecedented $1 trillion compensation plan for CEO Elon Musk, putting the spotlight on Musk's hold on the electric-vehicle maker as it looks to pivot into robotaxis and humanoid robots.
