Tesla Chief Executive Elon Musk said on Wednesday that the company’s Full Self-Driving software Version 14.3 has entered employee beta testing and is expected to reach a broad public release by the end of the week.
“FSD 14.3 is in Tesla employee beta now and will probably go to wide release end of week,” Musk wrote on X, in a post that received 2.5 million views.
On March 19, Tesla’s CEO had said that the new version was “in testing right now,” while adding that a “wide release” would roll out “in a few weeks.”
The update, which Musk has previously described as “the last big piece of the puzzle” for the software’s reasoning and logic capabilities, was originally slated for release in December 2025 but was delayed as Tesla instead shipped a series of incremental v14.2.x builds focused on stability.
Version 14.3
Tesla has not yet published detailed release notes for v14.3.
However, Musk said in November that the update would add “a lot of reasoning and RL (reinforcement learning)” to the system’s decision-making.
The company’s Vice President of AI Software, Ashok Elluswamy, recently confirmed that reasoning capabilities were already present in v14.2 but said additional improvements were planned.
The v14 generation, which began rolling out in late 2025, represented the largest architectural upgrade since Version 12.
It features a significantly higher parameter count, improved context and memory, and what Tesla owners have described as more human-like driving behaviour.
The current production version for Hardware 4 vehicles is FSD v14.2.2.5, which has been rolling out since mid-March.
Version 14.3 is expected to target HW4-equipped vehicles first. A separate version called FSD v14 Lite is being developed for older Hardware 3 vehicles, with a release anticipated in late June.
Record Intervention-Free Driving
The announcement comes after Tesla owner David Moss completed a 12,961-mile streak across 30 US states on FSD v14.2 without a single disengagement — a record the company promoted through an official video last week.
Tesla said in February that vehicles had driven a cumulative 8.3 billion miles using FSD (Supervised).
Musk has cited internal data showing approximately 5.3 million miles between accidents for FSD users as of mid-March, compared with 660,000 miles per accident for the average US human driver.
Austin Robotaxi Operations
Tesla has been operating an unsupervised robotaxi service in Austin, Texas, since June 2025, using unmodified production vehicles with no safety driver behind the wheel.
Musk said in January that Tesla would need approximately 10 billion miles of real-world data to achieve truly safe unsupervised self-driving at scale, citing the “long tail of complexity” in real-world driving conditions.
European Rollout
The software is still awaiting regulatory approval in Europe.
Tesla has been running supervised FSD test rides — with a Tesla employee driving — in Germany, France, Italy, Denmark, and Switzerland since late 2025.
The Netherlands is expected to become the first European country to permit deployment of FSD, with the latest timeline pointing to April 20.
Tesla said earlier this year on X that the Dutch vehicle authority RDW had “committed to granting Netherlands National approval,” but the RDW subsequently clarified that it had only agreed to meet with Tesla to evaluate the system’s capabilities.
Subscription-Only Model
Tesla stopped selling FSD as a one-time purchase after February 14, shifting to a subscription-only model at $99 per month in the United States.
Musk said the price would rise as the software’s capabilities improve, with the most significant value increase expected when FSD transitions from supervised to fully unsupervised operation.
