It looks like Tesla may soon be replacing its archaic voice commands with something much more useful — a voice assistant.
Greentheonly, who often takes deep dives into Tesla software by decompiling the firmware and looking for changes, has now found the early integration of a voice assistant.
Voice Assistant Already Available in China
Tesla has already replaced its voice commands in China with a voice assistant that can not only control certain aspects of the vehicle using more natural language but can also answer common knowledge questions such as the current weather, stock quotes and more (video below).
Available Only on AMD?
Correction: Tesla’s voice assistant in China is only available on vehicles with AMD processors (MCU 3), and unfortunately not on older Intel-based (MCU 2) cars. If Tesla is utilizing the same core technologies in its upcoming voice assistant for other regions, we may see the same limitation.
Intel vehicles in China still use the voice command system we’re familiar with today.
Tesla Creating Own Assistant
According to Green's findings, it looks like Tesla may be rolling its own solution instead of integrating something like Amazon Alexa like Rivian has. Tesla created their own solution in China by using some of their own technology and several existing software solutions. However, some of them are only available in China so they don’t scale to support additional regions.
Grōk
The first thought that comes to mind is Tesla leaning on AI efforts by Grōk and xAI, which could help it support common knowledge questions and search the web for answers. However, that only gets Tesla partly there, as Alexa and Google Assistant already support a large ecosystem, one that may not be available if Tesla creates their own voice assistant. With Tesla’s solution, a driver may be limited to what devices they can control through the voice assistant, at least initially. Either way, just a more natural way to activate certain vehicle solutions will be an improvement over what’s available today. The ability to ask the assistant common questions will be the icing on top.
Wake Word
According to Green, the source code hinted at the voice assistant using a wake word, which would replace the need to press the scroll wheel on the steering wheel. Tesla has begun to use the left scroll wheel button for additional things lately such as wiper controls and a multi-function mode, so this may fit in with their plan.
It’s fun to speculate what the wake word would be or whether Tesla would add the ability to create your own. It could be something as simple as ‘Hey, Tesla’, ‘Grok’, or something more humorous as Tesla has a knack for. Unfortunately, there weren't any hints on what the actual wake word would be, but being able to set a destination, play a specific song or ask the assistant for the weather will be a much-needed improvement.
Supported Models
It's not clear which models Tesla would support a voice assistant, but with the release of software v12 with update 2024.14.3, Tesla is starting to leave more features out of older Intel-based vehicles. While a voice assistant may not necessarily be computationally heavy, it may depend on Tesla's implementation and whether voice commands are transcribed on device or carried over the internet for transcription.
Voice Model
In the software, there are references to Microsoft's text-to-speech technology and specifically to a voice named “Jenny Neutral.”
The “Jenny Neutral” voice seems like an acceptable voice, bringing a natural-sounding voice to Tesla's voice assistant, although it doesn't differ much from what you find on other assistants. You can view an example of Microsoft’s “Jenny Neutral” voice in the video below.
Tesla has been more mindful lately about adding information for unreleased features to its software to help prevent leaks, so by the time something like this is found by Green, it usually doesn't take long before it becomes available, although this could also make for an exciting Christmas present.

Tesla has officially launched FSD in Mexico. This is the third expansion of FSD since it was first launched in the United States.
The news was shared by Tesla Owners Mexico on X, followed by confirmation from Tesla AI with a simple but exciting message: "¡Hola México!"
FSD Global Expansion Timeline
Tesla has set some lofty goals for itself, announcing in their FSD roadmap that it expects FSD to be ready to roll out internationally in Q1 and expand to right-hand drive markets in Q2. While it’s not clear whether Tesla still expects to meet these targets, this is the latest information that was shared in September 2024:
Q1 2025: FSD is expected to launch in Europe and China, pending regulatory approval.
Q2 2025: FSD rollout for right-hand drive (RHD) markets, with a flexible timeline based on approval processes.
Tesla has faced regulatory hurdles, particularly in China, where FSD testing was recently put on hold. One major hurdle is China’s strict data regulations, which require all training data to be collected and stored within the country. This means Tesla cannot rely on its existing U.S.-based data centers and must build local infrastructure to comply with government policies that prevent vehicle data from leaving China.
Additionally, since FSD relies heavily on fleet data, Tesla won’t be able to leverage its vast global dataset. Instead, the company will need to retrain its AI models using data exclusively gathered from vehicles operating within China. These constraints add complexity to Tesla’s FSD rollout, potentially delaying its expansion in the region.
After initially launching FSD Beta in the U.S. to a small group of influencers, Tesla expanded access to more users through its Safety Score program in late 2021. At first, only those with a perfect score of 100 were eligible, but as FSD improved and Tesla grew more confident in its performance, the requirement was gradually lowered.
In March 2022, Tesla took its first step beyond the U.S. by introducing FSD in Canada with the release of v10.11.1. Since then, Tesla has expanded FSD to Puerto Rico, and now, the launch in Mexico marks another major expansion of the software.
This news will likely raise excitement among users outside of North America who have been waiting for FSD for years. With regulatory hurdles in China presenting unique challenges, Tesla may shift its focus to expanding FSD in Europe and Oceania first.
Meanwhile, Tesla also focuses on launching its Robotaxi network, set to debut in Austin, Texas, in June. The upcoming Cybercabs in Austin could be running early builds of FSD v14 or a specialized version designed for Unsupervised FSD.
Like so many other things happening at Tesla right now, it’s an exciting time as Tesla prepares Unsupervised FSD for the Cybercab, continues the expansion of FSD, and works out all the details of its robotaxi network, such as the cleaning hubs and wirelessly charging capabilities.
In the latest episode of Jay Leno’s Garage, Tesla’s VP of Vehicle Engineering, Lars Moravy, confirmed that the new Model Y will feature adaptive headlights.
As Moravy was talking about the updated headlights in the vehicle, which now sit a few inches lower than before, he stated that in a couple of months, Tesla will add adaptive headlights in the U.S.
While Tesla has already introduced adaptive headlights in Europe and the Indo-Pacific, the feature has yet to make its way to North America.
Originally delayed in the U.S. due to regulatory issues, manufacturers have been able to implement adaptive headlights since mid-2024. Meanwhile, competitors like Rivian and Mercedes-Benz have already rolled out their own full matrix headlight systems, matching what’s available in other regions.
Update: This article has been updated to clarify that adaptive headlights will indeed be launched in the U.S., shortly after the vehicle launching in March.
Currently, Tesla in North America supports adaptive high beams and automatic headlight adjustment for curves, but full matrix functionality has yet to be rolled out. Meanwhile, matrix headlights are already available in Europe, where they selectively dim individual beam pixels to reduce glare for oncoming traffic and adapt to curves in the road.
It was surprising that matrix functionality wasn’t included in the comprehensive 2024 Tesla Holiday Update. This feature would likely improve safety ratings, so we can only assume Tesla is diligently working to secure regulatory approval.
Adaptive Headlights on Other Models
Lars didn’t confirm whether the refreshed Model Y comes with the same headlights as the new Model 3 and the Cybertruck, instead simply calling them "matrix-style” headlights.
The headlights on the new Model Y appear very similar to those available in the 2024+ Model 3, possibly meaning these other models will also receive adaptive headlight capabilities in the next couple of months.
For vehicles with older-style matrix headlights, it’s unlikely that adaptive beams support will launch at the same time, but they will hopefully become available soon afterward.
