Tesla hacker @greentheonly uncovered groundbreaking details about the Grok AI assistant in firmware 2025.20.
The update includes 13 interactive personality icons, a "Language Tutor" mode, and hidden navigation optimizations. Here’s what we know.
1. Hardware Compatibility
Grok exclusively supports Tesla vehicles with AMD Ryzen chips. Older Intel-based models are currently excluded.
-
Tesla previously used this "AMD-first" strategy for voice assistant rollouts in China.
-
Future Intel support remains possible but unconfirmed.
2. Release Timeline
The update’s icon assets suggest Grok is nearing completion. Deployment will likely follow Tesla’s phased approach:
-
Employee testing (initial phase)
-
Eligible owners (AMD-equipped vehicles)
-
Potential subscription (unclear if Premium Connectivity is required)
3. Grok’s 13 Personality Modes
The firmware reveals 13 distinct personality icons, including:
-
Language Tutor: Supports in-car language learning.
-
Storyteller: Tailored for children.
-
FSD Companion: Optimized for autonomous driving.
4. Hidden Navigation Feature
Firmware 2025.20.3 includes a smart energy-saving tool for frequent routes:
"This route is typically driven at X mph. Slow down by Y mph to save Z% for the rest of this trip."
Example:
-
Detects average speed: 66 mph
-
Suggests reducing speed by 5 mph to gain 1% range.
-
Most useful in low-battery scenarios.
This data may later enhance Robotaxi and FSD route optimization.
5. Technical Scope & Future Potential
-
Works in manual and FSD modes.
-
Multi-user adaptation: Kid-friendly modes confirmed.
-
Musk hinted at "ask anything" functionality.
Grok’s deep system integration could redefine in-car AI. AMD vehicle owners will likely get first access.
