Tesla has pushed a third wave of the 2026.14.6.12 update, reaching approximately 1,540 additional vehicles in the last few minutes according to Teslascope fleet data.

π UPDATE β June 24, 2026
Tesla has kicked off a second wave of the 2026.14.6.12 rollout, pushing FSD V14.3.4 to approximately 1,320 additional eligible AI4 vehicles as of 07:25 UTC today, per Teslascope fleet data. If you haven't received the update yet, this expanded wave means more owners should see the OTA notification arriving shortly. Check your Tesla app or touchscreen under Software β Update Available to see if you're in this batch.
Tesla has begun pushing software version 2026.14.6.12, the latest build in the 2026.14.6 branch, carrying Full Self-Driving (Supervised) v14.3.4. The update was first detected on a Cybertruck AWD in Arizona on June 23, 2026, and multiple trackers confirmed the FSD version bump within minutes. If you're on Hardware 4 in North America, this one may be heading your way.
What's in This Update
The headline here is FSD (Supervised) v14.3.4 β the same version that began rolling out with 2026.14.6.10 around June 11-13 and continued with 2026.14.6.11 around June 15-21. Version 2026.14.6.12 appears to be a new build carrying the same FSD payload, likely with minor under-the-hood fixes. Sawyer Merritt confirmed the release notes are unchanged from prior v14.3.4 builds.
That said, v14.3.4 itself is a meaningful FSD update. According to verified sources, the key improvements include:
- 20% faster reaction time β achieved through a rewritten AI compiler and runtime using MLIR
- Improved neural network vision encoder β better performance in rare and low-visibility scenarios, stronger 3D geometry understanding, and expanded traffic sign recognition
- Upgraded Reinforcement Learning (RL) training stage in the FSD neural network
- Reduced lane biasing and minor tailgating behavior
- Smarter parking β more decisive spot selection, improved location pin prediction
- Better emergency vehicle and school bus response, plus improved handling of right-of-way violators and small animals
- Actually Smart Summon max speed raised to 8 mph (13 km/h)
- Unified model across Actually Smart Summon, FSD, and Robotaxi
- New passenger-facing UI with status prompts and an intervention-free FSD streak tracker
Who Gets It First
The initial sighting was on a Cybertruck AWD (2024) in Arizona. FSD (Supervised) v14.3.4 is a North America-only rollout β European vehicles are currently receiving FSD v14.2.2.6 instead. The update targets Hardware 4 (HW4/AI4) vehicles. Rollout of the broader 2026.14.6 branch has been gradual: earlier builds reached roughly 1.4β4.9% of the fleet before this newest build appeared, so expect a phased push over the coming days.
