Optimus
Musk calls it the biggest product in history. On October 21, 2026 production began on a million-a-year line in Fremont — without the robot ever having been formally shown. The complete story, promises and all.
Optimus is Tesla's general-purpose humanoid robot: a five-foot-eight machine running the same vision-based AI stack as the cars, meant first for Tesla's own factories, then for sale to other companies, then — Musk says — for everyone.
Where it stands, October 2026
On the Q3 call Tesla said “early production on a high-volume line in Fremont” has begun, in the space where Model S and X were built until May. These are the first “production-quality” Optimus units, launching with the Gen 3 design; Gen 4 will arrive by the time the Giga Texas factory comes online. Not a Tesla App
Reaching 20,000 robots a week will take “at least a year, maybe a little longer” on a ramp Musk described as “a shallow slope and somewhat bumpy.” External deliveries to other companies are expected around the end of 2027, industrial customers first. The AI5 chip goes into Optimus around April 2027. The hand remains the hardest piece of hardware, per hardware lead Konstantinos Laskaris. Q3 call
Optimus Academy
Tesla plans to put 10,000–20,000 robots to work at Fremont practising tasks purely to generate training data for the next AI model — a factory whose product is experience.
What hasn't happened: a formal Gen 3 unveil (promised for Q1 2026), a non-scripted public demo (Musk promised a video within “a month or so” on October 21), any reservation program (Musk said “No” on October 30 to a report that orders would open in December), and any robot doing “useful work” in a factory by the time Musk admitted in January 2026 that none yet were.

From a dancer in a suit to a production line
“Tesla Bot” announced at AI Day
A 5-foot-8, 125-pound humanoid that can carry 45 pounds. A person in a spandex suit dances on stage.
AI Day 2: it walks
The “Bumble C” prototype walks unaided for the first time; a sleeker Gen 1 body is carried out.
Gen 2
Slimmer, faster, 11-degree-of-freedom hands; it handles an egg.
The teleoperation question
A shirt-folding video turns out to be teleoperated; critics say factory-task clips were too.
The first production promise
Limited production in 2025 with more than 1,000 units in Tesla factories; outside sales possibly 2026.
“We, Robot”
Optimus units pour drinks and chat with guests — later confirmed to be teleoperated or voice-assisted. Musk floats $20,000–30,000 long-term. The 22-DOF Gen 3 hand is shown.
10,000 in 2025
Musk targets ~10,000 built in 2025 (later halved) and ~1,000 doing useful work by year-end.
Program head leaves
Milan Kovac resigns; Ashok Elluswamy adds Optimus to FSD.
Popcorn at the Tesla Diner
A unit reportedly fails on day one and is teleoperated.
Gen 3 in “February or March”
Musk promises the reveal for early 2026 with limited production that year; the roadmap is a 1M/yr line, then bigger.
A pay-package milestone
Musk's $1T award includes a tranche for 1 million Optimus-class robots delivered.
Model S and X sacrificed
Tesla ends S/X production to free Fremont for Optimus lines. Musk admits no robot is yet doing useful work.
Q1 unveil missed
“Optimus 3 is walking around, but needs some finishing touches before it's ready to be shown.”
Production “quite slow,” late July or August
The 2026 rate is “literally impossible to predict” — about 10,000 unique parts. Fremont for 1M/yr; Giga Texas 10M/yr from 2027. Gen 3 hand patents show ~25 actuators per hand.
Last Model S rolls off
The S/X line is torn down in 46 days over the summer.
“Volume production” dropped
The Q2 letter removes the phrase for Optimus and Cybercab. Musk: “Optimus production will be extremely slow at first, as everything is new.”
Suppliers certified
Tuopu, Joyson and Sanhua named mass-production suppliers.
Production begins
Early production on the Fremont line; Optimus Academy announced; “I remain convinced that Optimus will be the biggest product on Earth.”
No December reservations
Musk shoots down a report of a waitlist with a single word.
Gen 3, as far as anyone knows
| Gen 2 (Dec 2023) | Gen 3 (2026) | |
|---|---|---|
| Hands | 11 DOF | 22 DOF, tendon-driven, ~25 actuators per hand |
| Height / weight | ~5'8", ~125 lb planned | Same target; 45 lb carry |
| Actuators | Rotary and linear | Planetary roller-screw |
| Compute | HW4-class | AI4 now; AI5 (~5× two AI4 chips) ~Apr 2027 |
| Price | — | $20,000–30,000 long-term target; no price announced |
| Availability | Internal | Internal; external sales ~end-2027 |
Hand details come from patents published in April 2026 and secondary reporting. Battery life, full specs and price remain unconfirmed. Optimus overview
Why Tesla is betting the company on it
Musk said on October 18, 2026 that Optimus and Cybercab will make up “the vast majority” of Tesla's value. R&D spending rose 69% year over year in Q3 2026, largely on Optimus, Cybercab and compute. The company gave up two of its most iconic cars to build robots in their place, is building a second robot factory in Austin with a 10-million-a-year target, and is building Terafab partly to supply the chips they will need. Q3 results
Executives say Optimus's production cost is trending toward the Cybercab's expected manufacturing cost. SpaceX's Mars plan, meanwhile, calls for Optimus robots to land before humans — one of the reasons Musk gives for merging the two companies. That side of the story is on SpaceX Unpacked.
