Tesla has begun pushing FSD (Supervised) v14.3.3 bundled with the Spring Update, firmware version 2026.14.6.7, to early access owners in the USA and Canada. The rollout is live now — and there's more packed into this update than the single release note line suggests.
Here's everything confirmed so far about what's changed.
What's in 2026.14.6.7
| Change | Type | Models |
|---|---|---|
| Enhanced Driver Monitoring System | Official | All with cabin camera |
| Smart Summon speed increase (6 → 8 mph) | Official | All |
| 20% faster AI reaction time | Official | All FSD-equipped |
| Intervention-Free Streak Counter | Official | All FSD-equipped |
| Upgraded neural network vision encoder | Official | All FSD-equipped |
| Hey Grok hands-free wake word | Official | All |
1. Driver Monitoring Gets Smarter — and Less Annoying
The headline change in the official release notes is an upgraded driver monitoring system. According to verified reports, the update improves eye gaze tracking sensitivity, better handles eyewear (glasses, sunglasses), and maintains higher accuracy in variable lighting — think tunnels, dawn, dusk, and direct sunlight. For owners with a cabin camera, this translates directly to fewer steering wheel nag prompts during FSD sessions. That's been one of the most consistent complaints from daily FSD users, and this update directly addresses it.
2. Actually Smart Summon Gets a Speed Bump
The maximum speed for Actually Smart Summon has been increased from 6 mph to 8 mph (13 km/h), according to teslaoracle.com. It's a modest change on paper, but in practice it means the feature covers parking lot distances noticeably faster. If you've ever watched your car crawl toward you from the far end of a lot, you'll appreciate the difference.
3. The AI Compiler Was Rewritten for 20% Faster Reactions
Tesla rewrote its AI compiler and runtime for this release, resulting in a claimed 20% improvement in system reaction time. This isn't a UI change — it's an under-the-hood upgrade that affects how quickly FSD processes and responds to what it sees. Faster reaction time matters most in complex urban scenarios where split-second decisions are required.
4. A New Neural Network Vision Encoder
The update ships an upgraded neural network vision encoder alongside an improved Reinforcement Learning (RL) training stage. According to teslaoracle.com, this strengthens 3D geometry comprehension, improves performance in low-visibility conditions, and expands traffic sign recognition. These are the kinds of foundational improvements that don't show up as a single feature but compound across every FSD mile driven.
5. Track Your Longest Intervention-Free Streak
A new live statistic now displays how far you've traveled in FSD (Supervised) without an intervention, along with your personal longest streak. It's a small gamification touch, but it gives owners a concrete way to see their FSD improving — and gives Tesla richer feedback on which routes and conditions produce the cleanest runs.
6. Say "Hey Grok" Hands-Free
Native hands-free wake word support for xAI's Grok assistant is included in this release. Rather than navigating to the Grok interface manually, owners can now invoke it by voice — keeping eyes on the road and hands on the wheel. For FSD users already relying on voice commands, this is a natural extension of the in-car experience. Check out our FSD coverage for more on how these AI integrations are evolving.
Who Gets It First
The rollout began with early access owners in the USA and Canada. If you have FSD (Supervised) on your vehicle, check Software → Software Update in your Tesla app or touchscreen. The broader fleet push typically follows within one to two weeks of the early access wave.
