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.
