Proposition (held fixed): Would Tesla have thousands of Optimus robots doing useful work in its own factories by the end of 2025? Broader production-rate dates are on the Optimus production page.
end of 2025“several thousand” in the factories
Jul 2025revised to “a few hundred”, for version 3
Oct 2026early production on the Fremont line
Then vs now · Optimus in Tesla factories
From several thousand useful Optimus robots in 2025 to early production on a high-volume line in 2026.
“But we expect to have several thousand Optimus robots produced and doing useful things by the end of next year in the Tesla factories and then in 2026 ramping up production quite a bit.”
What did not change: Optimus built first for Tesla’s own factories · a slow start, then a steep ramp · version 3 as the design to scale. ElonsFAQ corpus · verified 2026-10-23 · unofficial.
Editorial calendar reading: “next year” from Jun 2024 = 2025.
22 July 2024, on X:
“Tesla will have genuinely useful humanoid robots in low production for Tesla internal use next year and, hopefully, high production for other companies in 2026”
“But we expect to have several thousand Optimus robots produced and doing useful things by the end of next year in the Tesla factories and then in 2026 ramping up production quite a bit.”
“But will we succeed in making several thousand? Yes, I think we will. Will those several thousand Optimus robots be doing useful things by the end of the year? Yes, I'm confident they will.”
27 July 2025, X Takeover, on whether to build thousands of version 2 robots or wait for version 3:
“we maybe have I don't know a few hundred robots instead of a few thousand robots by the end of the year and I think the right decision was to go with version three and then scale production significantly next year.”
Company figures, not Elon quotes (Tesla Q3 2026 Update · Single source for this wording): “Optimus production began in Fremont on our high-volume lines. The bots coming off this line are the first production-quality bots that we have manufactured.” The capacity table lists Robotics in California as “Optimus – Early Ramp.” The filing gives no factory headcount for 2025.
What changed
Item
Then (2024–Apr 2025)
Now (Jul 2025–Oct 2026)
How many in 2025
“over a thousand, maybe a few thousand”; “several thousand”; “a legion”
“a few hundred … instead of a few thousand”, after choosing version 3 (Jul 2025)
What they would be doing
“working at Tesla”; “doing useful things … in the Tesla factories”
Early production on the Fremont high-volume line (Oct 2026); company status “Early Ramp”
Outside customers
“hopefully, high production for other companies in 2026”
Still Tesla-internal first; version 3 chosen as the one to scale
What did not change
Who gets the first robots: Tesla’s own factories, to “iron out the issues”.
The shape of the ramp: low internal production, then a steep climb. Elon later called that an S-curve.
Neutral conclusion
From Jun 2024 through Apr 2025, Elon dated thousands of useful Optimus robots inside Tesla to the end of 2025 — “a few thousand”, “several thousand”, “a legion”. In May 2025 he said a 1,000-a-month line was still many months away. In Jul 2025 he said Tesla might have a few hundred robots instead of a few thousand by year-end, because version 3 was the right design to scale. On the Q3 2026 call (22 Oct 2026) he said early production had started on the high-volume line in Fremont. Tesla’s Q3 2026 update (company) calls those the first production-quality bots and lists Optimus in California as early ramp. This compares dated wording; it makes no claim about motives.
Scope
Indexed ElonsFAQ corpus (transcripts and X posts); not every Elon Musk interview.
YouTube wording is from automatic captions (ASR); fillers such as “uh” are kept as spoken.
Calendar readings of relative dates (next year, this year, in 2 years) use the statement date.
Latest Tesla and SpaceX operating items are company statements, not Elon quotes, and are labeled.
