Teslascope has flagged a new factory-only software build — version 2026.14.100 — appearing on recently delivered Tesla vehicles as of May 29, 2026. Factory updates like this one are distinct from standard OTA rollouts: they're pre-loaded at the production stage and are never pushed to existing vehicles in the field.
The version number places this squarely within the 2026.14 "Spring Update" lineage, which has been rolling out publicly since mid-April. The series kicked off with 2026.14.1 on April 16, progressed through several sub-versions, and most recently landed on 2026.14.6.6 — which carries FSD (Supervised) v14.3.3 and had reached over 7% of tracked vehicles within five days of this writing, according to Teslascope data.
A factory build numbered .100 typically represents a stabilized internal baseline that Tesla loads onto vehicles coming off the production line. It doesn't necessarily map directly to any public-facing version, but it does confirm that new deliveries are shipping with software rooted in the 2026.14 branch — meaning buyers taking delivery right now are starting with the full Spring Update feature set already on board.
What the 2026.14 series brings
For anyone just taking delivery of a new Tesla, the 2026.14 branch is a meaningful starting point. Key additions across the series include "Hey Grok" voice activation with location-based reminders, Blind Spot Warning Accent Lights that flash red when a turn signal is engaged near a detected object, Pet Mode customization with named pet profiles, and Music App queuing for Apple Music and Spotify. The Energy app also gained a revamped Trips feature for multi-leg journey planning and energy tracking.
Whether 2026.14.100 introduces anything beyond what's already documented in the public sub-versions remains to be seen — factory builds occasionally contain early code for features not yet activated in production software. Teslascope's rollout tracker is the best place to watch for any divergence as more newly delivered vehicles check in.
