Tesla Optimus 3 production updates: the dated log

Tesla has never published a cumulative Optimus build count. The Fremont line promised to start producing in "late July or August" 2026 has no announced start date as of August 7, and the Gen 3 reveal promised for the middle of 2026 has not happened.
Tesla has never published how many Optimus robots it has built. I went looking through the quarterly decks, the press releases and the earnings-call coverage, and no such number appears in any of them. Every figure attached to this program is a capacity, a target or a date. None of them is an output.
That absence is the reason this page exists. Below is the update log: dated entries on Optimus 3 production, the line, the parts and the ramp, kept separate from the wider promise ledger in Elon Musk's robot claims, the dated archive. Claims about what Optimus will one day do live there. This page tracks whether anything is coming off an assembly line.
Where it stands today
| Question | Answer, August 7 2026 |
|---|---|
| Where the line is | Fremont, California, in the space vacated by Model S and Model X |
| Promised production start | "late July or August," said on the Q1 call, April 22, 2026 |
| Announced production start | None. Tesla has not said the line has started |
| Cumulative units built | Never published |
| Gen 3 reveal | Promised for "probably middle of this year," has not happened |
| Design capacity | Fremont 1 million a year; Giga Texas 10 million a year from 2027 |
| Price and order channel | No price, no order page. The $20,000 to $30,000 figure (October 10, 2024) is a target at volume, logged as a claim on the tracker entry |
The log
Production entries only. Demos, dance videos and diner appearances are covered elsewhere.
| Date | Production event | What it was |
|---|---|---|
| Jun 13, 2024 | Musk says limited production starts in 2025, 1,000-plus robots working in Tesla factories, production for outside customers in 2026 | A target. Neither half happened on schedule |
| Jan 31, 2025 | Musk says Tesla aims to build roughly 10,000 Optimus units that year, calling it ambitious | Missed. No 2025 output figure was ever published |
| Jun 2025 | Program head Milan Kovac leaves after nine years; Ashok Elluswamy takes the program | Leadership change during the intended ramp year |
| Jul 3, 2025 | Production reported delayed for a redesign: joint motors overheating, hands short on load capacity, transmission components wearing out, weak battery life. Parts secured for over 1,000 robots; several units built, moving batteries at under half a human's rate | Supply-chain reporting, corroborated by The Information. The closest thing to an output number on record |
| Sep 19, 2025 | Ashish Kumar, two years leading the Optimus AI team, leaves for Meta | Second senior departure in four months |
| Jan 28, 2026 | Musk admits no Optimus robots are doing useful work at Tesla | The 2024 promise of 1,000 working robots, formally retired |
| Apr 22, 2026 | Q1 call: Gen 3 reveal pushed to "probably middle of this year"; production to start at Fremont in "late July or August," output "quite slow." No 2026 unit target given | The current live promise, and the one this log is watching |
| Early May 2026 | Last Model S and Model X built at Fremont after 14 and 11 years; teardown of the line begins, signature delivery ceremony May 20 | Real, verifiable, physical. Two products cancelled to make room |
| Jul 1, 2026 | Musk visits Fremont to mark the changeover | A photo opportunity at a converted building |
| Jul 2, 2026 | Musk rejects the theory that Tesla is secretly ahead: "Optimus production will be extremely slow at first, as everything is new. This is not like making a car." | Expectation management, three weeks before the promised start |
| Jul 10, 2026 | Tesla publishes video of the teardown, completed in 46 days | Demolition, filmed. Not production |
| Jul 22, 2026 | Q2 call. Musk: "No humanoid robots today can do generalized tasks without programming, but Optimus will be the first to do it." Tesla stock falls 12% on the results | A capability claim in the quarter production was supposed to begin. No unit count, no start date |
| Jul 30, 2026 | Elluswamy restates the 10 million a year figure for the Texas plant | The largest number in the program, attached to a plant that is still being built |
What "extremely slow" is describing
Musk's own framing on the April 22 call is the most technically specific thing Tesla has said about this ramp. Optimus has roughly 10,000 unique parts, none of them previously mass produced, and the line will "move as fast as the least lucky, slowest, dumbest part in the entire 10,000." He called this year's production rate literally impossible to predict, and declined to give a number. Tesla publishes the call itself, so the promise this log is watching can be heard rather than paraphrased.
Compare that to January 2025, when the same executive gave a number for the year without hesitation: 10,000 robots. The forecasting confidence has gone down as the factory has become more real. Read that as a good sign about the disclosure and a bad sign about the schedule.
The conversion itself is the part nobody disputes. Tesla ended Model S and Model X production to free the floor, tore the old line out in 46 days, and filmed it. Whatever else is true about Optimus, the company has spent two of its own products on the bet.
The number that would settle this
One cumulative build count would end most arguments about this program, and Tesla publishes a quarterly production table already. Optimus has never appeared in it.
Other makers have chosen differently. Figure said it had built more than 350 Figure 03s by April 29, 2026. AgiBot marked its 15,000th robot on June 28. Both figures are self-reported and both are checkable against later statements, which is what makes them useful. The comparison runs cell by cell in Figure vs Tesla Optimus, and the whole category's shipped-versus-promised scorecard is in what actually shipped in 2026.
Tesla's only public quantity for units in existence remains secondhand: the July 2025 supply-chain reporting that parts had been secured for more than 1,000 robots and that several built units were moving batteries in a Tesla workshop at less than half a human's throughput. That was thirteen months ago and it came from suppliers, not from Tesla.
One figure I could not source
Electrek's July 2 piece describes Tesla's stated 2026 target as 50,000 to 100,000 units, and a Fremont run rate of 1 million a year by the end of the year. I cannot find Tesla or Musk saying either of those on the record, and on the April call Musk specifically refused to give a 2026 production number. Until a primary source turns up, treat the 50,000 to 100,000 range as unattributed. The 1 million figure is real as a design capacity for the line. Nobody at Tesla has claimed the line is running at it.
What would actually move this log
Four things, in ascending order of how much they would tell you.
A Gen 3 reveal with a date on it. The reveal has slipped from "closer to production start" to mid-2026 to nothing, and it is the cheapest of the four to deliver.
A stated production start. Teslarati reported on July 10 that limited Gen 3 production was already underway at Fremont ahead of full-scale output; Tesla itself has announced nothing. A one-sentence confirmation with a date would convert a rumor into a milestone.
A unit count in a quarterly release. Any number at all, including a small one.
An Optimus doing paid work with nobody driving it. The January 2026 admission set the bar here at zero, and nothing since has raised it publicly.
Tesla filmed the demolition. A production start will get a video too, probably a good one. The number that would settle the question needs no footage at all: one cumulative build count, printed next to the vehicle line items, in a document the company already publishes every three months.
