Tesla’s Full Self-Driving (FSD) beta version 12 has been a hot topic over the last several months, representing an important switch that’s expected to help unlock higher levels of autonomy. And while the highly anticipated FSD v12 hasn’t yet been deployed publicly, some think that it could go out to a wider audience by the end of this month.
Last month, Tesla began rolling out the FSD beta v12.1 to Wave1, a group made up of over 15,000 employee vehicles. CEO Elon Musk went on to say that Tesla is currently performing extra testing on v12 before the software sees a wider release to the public.
In a recent look at where the FSD beta v12 is at ahead of its release, Teslascope shared a detailed breakdown of events leading up to this point on X over the weekend, adding that they’re “hopeful” that the software will be released sometime in late January. In addition, the account says that Tesla has begun internal tests of Actually Smart Summon (ASS), which has a “very likely chance” of going out later on in the first quarter.
Teslascope also points to recent feedback on the FSD beta v12 received from employees in the Wave1 group, with most answering that the software did indeed include some substantial improvements. These are summarized below, based on at least a dozen reviews shared with Teslascope from employees in California:
Tesla FSD beta v12.1: improvements to “human-like behavior” and general stability
- 72 percent said FSD beta v12.1 includes improvements in “human-like behavior” and general stability.
- 20 percent said there was no change to “human-like behavior” and general stability.
- 8 percent said these factors had worsened.
Tesla FSD beta v12.1: improvements to roundabout encounters
- ~40 percent said FSD beta v12.1 improved roundabout encounters had improved.
- ~50 percent said there was no change to roundabout encounters.
- ~10 percent said these factors had worsened.
Tesla FSD beta v12.1: improvements to lane-keeping
- 37 percent said FSD beta v12.1 offered improvements to lane-keeping.
- 60 percent said there was no change to lane-keeping.
- 3 percent said these factors had worsened.
Despite the hopefulness, the account also notes that the Cybertruck release has caused Tesla to put some extra energy into creating a stable FSD beta build for the vehicle, though Musk recently noted that the electric pickup would be the lowest priority for the FSD beta. Because of the extra effort put into this, the account says that delays could be possible and that they’re continuing to monitor the ongoing deployment of the version to those within the Wave1 group.
Tesla unveiled plans for the FSD beta v12 last year, featuring the elimination of over 300,000 lines of human-written code that previously controlled functions such as steering, acceleration and braking. Instead, v12 is expected to rely much more heavily on its neural network, training its artificial intelligence (AI) through massive amounts of real-time driving footage, and using the neural network to actually control the vehicle, rather than just detecting objects.
Musk also debuted the FSD beta v12 in a live stream in August, and he has also said that the version would lose its “beta” designation. Tesla began rolling FSD v12 out to employees in November, and screenshots from the Wave1 group appeared to show that the version will still use the beta moniker.

Tesla FSD (Supervised) fleet passes 8.4 billion cumulative miles
Tesla’s Full Self-Driving (Supervised) system has now surpassed 8.4 billion cumulative miles.
The figure appears on Tesla’s official safety page, which tracks performance data for FSD (Supervised) and other safety technologies.
Tesla has long emphasized that large-scale real-world data is central to improving its neural network-based approach to autonomy. Each mile driven with FSD (Supervised) engaged contributes additional edge cases and scenario training for the system.
The milestone also brings Tesla closer to a benchmark previously outlined by CEO Elon Musk. Musk has stated that roughly 10 billion miles of training data may be needed to achieve safe unsupervised self-driving at scale, citing the “long tail” of rare but complex driving situations that must be learned through experience.
The growth curve of FSD Supervised’s cumulative miles over the past five years has been notable.
As noted in data shared by Tesla watcher Sawyer Merritt, annual FSD (Supervised) miles have increased from roughly 6 million in 2021 to 80 million in 2022, 670 million in 2023, 2.25 billion in 2024, and 4.25 billion in 2025. In just the first 50 days of 2026, Tesla owners logged another 1 billion miles.
At the current pace, the fleet is trending towards hitting about 10 billion FSD Supervised miles this year. The increase has been driven by Tesla’s growing vehicle fleet, periodic free trials, and expanding Robotaxi operations, among others.
With the fleet now past 8.4 billion cumulative miles, Tesla’s supervised system is approaching that threshold, even as regulatory approval for fully unsupervised deployment remains subject to further validation and oversight.

Elon Musk fires back after Wikipedia co-founder claims neutrality and dubs Grokipedia “ridiculous”
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Elon Musk fired back at Wikipedia co-founder Jimmy Wales after the longtime online encyclopedia leader dismissed xAI’s new AI-powered alternative, Grokipedia, as a “ridiculous” idea that is bound to fail.
Musk’s response to Wales’ comments, which were posted on social media platform X, was short and direct: “Famous last words.”
Wales made the comments while answering questions about Wikipedia’s neutrality. According to Wales, Wikipedia prides itself on neutrality.
“One of our core values at Wikipedia is neutrality. A neutral point of view is non-negotiable. It’s in the community, unquestioned… The idea that we’ve become somehow ‘Wokepidea’ is just not true,” Wales said.
When asked about potential competition from Grokipedia, Wales downplayed the situation. “There is no competition. I don’t know if anyone uses Grokipedia. I think it is a ridiculous idea that will never work,” Wales wrote.
After Grokipedia went live, Larry Sanger, also a co-founder of Wikipedia, wrote on X that his initial impression of the AI-powered Wikipedia alternative was “very OK.”
“My initial impression, looking at my own article and poking around here and there, is that Grokipedia is very OK. The jury’s still out as to whether it’s actually better than Wikipedia. But at this point I would have to say ‘maybe!’” Sanger stated.
Musk responded to Sanger’s assessment by saying it was “accurate.” In a separate post, he added that even in its V0.1 form, Grokipedia was already better than Wikipedia.
During a past appearance on the Tucker Carlson Show, Sanger argued that Wikipedia has drifted from its original vision, citing concerns about how its “Reliable sources/Perennial sources” framework categorizes publications by perceived credibility. As per Sanger, Wikipedia’s “Reliable sources/Perennial sources” list leans heavily left, with conservative publications getting effectively blacklisted in favor of their more liberal counterparts.
As of writing, Grokipedia has reportedly surpassed 80% of English Wikipedia’s article count.

Tesla Sweden appeals after grid company refuses to restore existing Supercharger due to union strike
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons.
Tesla Sweden is seeking regulatory intervention after a Swedish power grid company refused to reconnect an already operational Supercharger station in Åre due to ongoing union sympathy actions.
The charging site was previously functioning before it was temporarily disconnected in April last year for electrical safety reasons. A temporary construction power cabinet supplying the station had fallen over, described by Tesla as occurring “under unclear circumstances.” The power was then cut at the request of Tesla’s installation contractor to allow safe repair work.
While the safety issue was resolved, the station has not been brought back online. Stefan Sedin, CEO of Jämtkraft elnät, told Dagens Arbete (DA) that power will not be restored to the existing Supercharger station as long as the electric vehicle maker’s union issues are ongoing.
“One of our installers noticed that the construction power had been backed up and was on the ground. We asked Tesla to fix the system, and their installation company in turn asked us to cut the power so that they could do the work safely.
“When everything was restored, the question arose: ‘Wait a minute, can we reconnect the station to the electricity grid? Or what does the notice actually say?’ We consulted with our employer organization, who were clear that as long as sympathy measures are in place, we cannot reconnect this facility,” Sedin said.
The union’s sympathy actions, which began in March 2024, apply to work involving “planning, preparation, new connections, grid expansion, service, maintenance and repairs” of Tesla’s charging infrastructure in Sweden.
Tesla Sweden has argued that reconnecting an existing facility is not equivalent to establishing a new grid connection. In a filing to the Swedish Energy Market Inspectorate, the company stated that reconnecting the installation “is therefore not covered by the sympathy measures and cannot therefore constitute a reason for not reconnecting the facility to the electricity grid.”
Sedin, for his part, noted that Tesla’s issue with the Supercharger is quite unique. And while Jämtkraft elnät itself has no issue with Tesla, its actions are based on the unions’ sympathy measures against the electric vehicle maker.
“This is absolutely the first time that I have been involved in matters relating to union conflicts or sympathy measures. That is why we have relied entirely on the assessment of our employer organization. This is not something that we have made any decisions about ourselves at all.
“It is not that Jämtkraft elnät has a conflict with Tesla, but our actions are based on these sympathy measures. Should it turn out that we have made an incorrect assessment, we will correct ourselves. It is no more difficult than that for us,” the executive said.
