FSD Release Tracker

A clean tracker for Tesla main software releases, FSD (Supervised) branches, rollout status, hardware eligibility, and public prediction confidence.

Prediction

Next Public FSD v14.3.3 Wave

Late May / Early June 2026

Prediction based on current public v14.3.3 expansion, 2026.14.6 Spring Update install base, HW4 eligibility, and recent fleet tracking trends.

End of this week confidence (by May 30) 20–40%

Early June confidence (by June 5–10) 50–70%+

Mid-to-late June rollout outlook Near full HW4 rollout

The next wave could move faster than some past FSD updates because base software 2026.14.6 is already on roughly 63% of the fleet, making it easier for Tesla to push the FSD-specific 14.3.3 branch on top. HW3 vehicles remain on older v12/v14-lite branches for now.

Core Explanation

Main Software vs FSD Updates

As of May 24, 2026, Tesla continues deploying two separate types of over-the-air updates that roll out independently.

Main car software updates

Examples include the Spring 2026 Update and the 2026.14.x series. These handle UI, apps, audio, visualizations, safety features, and non-driving features.

FSD (Supervised) updates

Examples include FSD v14.3.3 on software 2026.14.6.6. These specifically update the Full Self-Driving neural network, driving behavior, and autonomy features. They are not tied to the main software branch.

Eligibility

What Determines Availability

Updates apply to current Tesla models, including Model S, Model 3, Model X, Model Y, and Cybertruck where hardware supports them. Rollouts are gradual and fleet-wide where eligible.

Model S Model 3 Model X Model Y Cybertruck

Hardware: HW4/AI4 gets the fullest FSD and some AI features, including the active v14.3.3 rollout. HW3 vehicles remain on older v12/v14-lite branches for now and may have limits on advanced FSD or AI features.
New models: Refreshed vehicles like Highland/Juniper-style Model 3/Y, refreshed S/X, and Cybertruck often receive priority or exclusive features.
Region: Many features are US-first but roll out worldwide over time.
Subscription/Purchase: FSD (Supervised) requires ownership or subscription.
Software version: Tesla does not tie updates to model-year numbers beyond the actual software version, such as 2026.14.6 plus FSD v14.3.2.

Spring 2026 Update

Key New Main Software Features

Self-Driving App: US, HW4 FSD-capable New 3, New Y, and Cybertruck. Includes single-tap subscription, usage stats, and activation info.

How To Verify

Check Your Vehicle

For the absolute latest on a specific vehicle, check Controls > Software in the car or use the Tesla app. Release notes appear there after install. Rollouts are staggered by VIN, hardware generation, region, and subscription status. Tesla frequently iterates with small FSD point releases and phased VIN-based deployments.

Sources are primarily aggregated from Tesla’s official release notes, tracker context such as Not a Tesla App, Teslascope, Tessie-style fleet data, and recent owner reports. Updates evolve quickly, so new FSD versions or Spring Update refinements could appear any day.
