FSD v15 complete software overhaul by end of 2026

“Version 15, hopefully by the end of this year, but certainly by early next year. That will be a complete overhaul of the software architecture, and will run on AI5.”

What actually happened

Quote promised Version 15 as a complete software-architecture overhaul that 'will run on AI5,' hopefully by end of 2026 / certainly early 2027. Fetched Sep 9 2026: Wikipedia Cybercab says production Cybercabs are using FSD v15 unsupervised, which is not yet available for consumer cars, and those Cybercabs run it on a modified Hardware 4 — not AI5. Teslascope's latest customer OTA (2026.27.6, Sep 8) is still FSD Supervised v14.2 / v14.3.9. Early v15 on the robotaxi fleet is not the complete customer overhaul on AI5. Deadline Dec 31 2026. Status stays pending. Wikipedia — Tesla Cybercab (fetched Sep 9 2026): fleet v15 unsupervised; not on customer cars / not AI5 ↗

Musk told investors FSD version 15 will be a ground-up architectural rewrite running on the AI5 chip, due 'hopefully' by end of 2026 and 'certainly' by early 2027. He also said large-scale unsupervised deployment should wait for that rewrite — making v15 the stated gate for the entire robotaxi expansion timeline.
