HW4/AI4: FSD 14.3.13, firmware 2026.38.5.10 and 2026.38.5.11, first listed Oct 20, 2026. That is the same row as the version page.
HW3: FSD 14.3 Lite, firmware 2026.33.5, 2026.38.5, 2026.38.5.1, 2026.38.5.10, and 2026.38.5.11, first listed Oct 6, 2026. Lite in the name is how this catalog marks the HW3 branch. There is no hardware column on the version table.
These numbers come from the same cached catalog the version pages use. The page revalidates every hour. It does not call an API on each pageview.
Teslascope’s Full Self-Driving list shows AI4 v14.3.13 on 2026.38.5.10 (October 20) and 2026.38.5.11 (October 24). Its HW3 list shows v14.3 Lite on 2026.33.5, 2026.38.5, 2026.38.5.1, 2026.38.5.10, and 2026.38.5.11.
Not a Tesla App titles 2026.38.5.10 and 2026.38.5.11 as FSD 14.3 Lite & 14.3.13, North America. Its 2026.38.5.11 notes page says that package is an updated 14.3.13 with the same notes.
Not a Tesla App lists FSD 14.2.2.6 on firmware 2026.39.6, labeled Europe, dated October 29, 2026. Teslant reports the same version on that firmware. Teslascope shows 2026.39.6 installing in European countries, including the Netherlands, Czechia, and Belgium, but it has no FSD 14.2.2.6 version page. This tracker has a 14.2.2.6 page at /version/fsd-14-2-2-6.
FSD Update is independent of Tesla, Inc. FSD on owner cars still needs a licensed driver who stays attentive. It is not fully autonomous.
