Musk clarified that it was version 2.5. In the clip the robot chats, offers to take the questioner to the kitchen for a Coke and walks slowly down a hallway, but no grasping is shown."]},{"h":"Hardware","p":["Compared with Gen 2, version 2.5 has smoother, rounder shell panels, better-covered joints, fewer visible seams and wires and a uniform metallic finish. Tesla has not officially stated its weight, degree-of-freedom count, battery runtime or walking speed, so such figures in third-party tables should be treated as estimates.","The headline hardware change promised for the next generation (V3) is a new hand with 22 degrees of freedom."]},{"h":"Software and AI","p":["Version 2.5 speaks through Grok voice mode from xAI. In the published video the robot admitted it lacked real-time information and the exchange had noticeable pauses. Commentators noted the demo said little about autonomy or dexterity."]},{"h":"Use cases and deployments","p":["Second-generation and interim Optimus units have appeared in public, for example serving popcorn at the Tesla Diner. Tesla says the first real job for the robots will be inside its own factories, on repetitive, boring or dangerous tasks."]},{"h":"Successor and production plans","p":["At the end of March 2026 Musk wrote that Optimus 3 was walking but needed finishing touches before being shown. Tesla is ending Model S and Model X production to make room in Fremont for an Optimus line designed for a long-term rate of one million robots a year, with a 10-million-a-year plant planned in Texas. As of this update we found no report of an official V3 unveiling."]},{"h":"Price and availability","p":["Version 2.5 is not for sale. Musk's long-term price target for Optimus is roughly $20,000 to $30,000 per unit."]}],"timeline":[["2023-12","Optimus Gen 2: 10 kg lighter, 30% faster, new hands"],["2025-09","Video of the gold Optimus V2.5 talking via Grok"],["2026-03","Musk: Optimus 3 is walking, reveal postponed"]],"faq":[["What is Optimus V2.5?","An interim version between Gen 2 and the planned third generation, with a redesigned shell and Grok-based conversation."],["Can I buy a Tesla Optimus?","No. Tesla plans to use the robots in its own factories first and sell them later."],["How much will Optimus cost?","Musk has talked about a long-term price of about $20,000 to $30,000."],["What are the specs of Optimus V2.5?","Tesla has not published official specs for this version; the known figures are for Gen 2 from 2023."],["Is Optimus V2.5 teleoperated?","Tesla has not said.
