Tesla's bipedal humanoid program. Generation 2 was unveiled on Tesla's official channels in December 2023; the announcement was covered verbatim by Electrek and Not a Tesla App, both quoting Tesla's own video for actuator count, hand DoF, neck articulation, and the weight-reduction-plus-speed-boost line. Tesla's investor materials confirmed Gen 3 timing on the Q4 2025 earnings call.
What makes Optimus distinct for the AI-hardware reader is the stack lineage: it runs Tesla's FSD vision-only end-to-end neural networks rather than a hand-engineered control pipeline. No LiDAR, no depth sensors — just cameras, the same architectural bet Tesla made on cars. Gen 3 moves every finger actuator into the forearm and routes tendons through the wrist, mirroring human anatomy.
Caveats worth flagging: Tesla does not publish an official Optimus spec sheet. The figures here trace to Tesla's December 13, 2023 announcement video plus the Q4 2025 earnings call; we lean on trade-press coverage that quotes those primary materials verbatim because tesla.com actively blocks scraping. Battery and runtime numbers are repeated across industry coverage but Tesla has not confirmed them in a public release. Treat them as best-available, not Tesla-official.
