Andrej Karpathy — the OpenAI co-founder who ran Tesla's Autopilot and Full Self-Driving programmes from 2017 until July 2022 — has joined Anthropic, the AI lab behind the Claude family of models. Karpathy announced the move himself on X on 19 May 2026, and Anthropic confirmed he is now part of its pre-training team, working under team lead Nick Joseph on the work that gives Claude its base knowledge and capabilities.
What Karpathy did at Tesla
Karpathy joined Tesla as Director of AI in June 2017 and was promoted to Senior Director of AI shortly after. During his five-year tenure he became the public face of Tesla's neural-network-first approach to driving, and his AI Day presentations in 2021 and 2022 are still the most widely-circulated reference for how Tesla's perception stack is put together.
The most consequential decision of his Tesla years was the 2021 transition to a vision-only stack — the removal of radar and, later, ultrasonic sensors from new vehicles in favour of an end-to-end neural network running on Tesla's in-house FSD computer. That bet underwrites every FSD release since, including the V14 branch and the unified Smart Summon / Robotaxi / FSD model that shipped earlier this month.
He left Tesla in July 2022, briefly returned to OpenAI in early 2023, and founded the AI-education startup Eureka Labs in 2024, where he had been working until this week.
Why this is industry-significant
Anthropic's hiring of Karpathy is the latest move in an increasingly visible talent war with OpenAI. The lab is, by recent reporting, on the verge of overtaking OpenAI on private-market valuation, and is bidding aggressively for senior researchers across the field. Joining the pre-training team rather than a fine-tuning, agents or product group is a deliberate signal: Anthropic is putting one of the field's best-known practitioners on the most foundational layer of its model stack.
For Tesla, the headline isn't operational — Karpathy hasn't been on the org chart for nearly four years — but reputational. The architect most publicly associated with Tesla's AI approach is now building a general-purpose AI lab's foundation models, not its driving stack.
What it means for FSD and European owners
Nothing in Karpathy's move changes the FSD release schedule, the regulatory situation for FSD (Supervised) in Europe, or the v14.3.3 rollout that began on 17 May. Tesla's current AI organisation is led by Ashok Elluswamy, and the operational continuity since 2022 has been clear in the cadence of FSD releases.
What is worth watching for European subscribers is the broader trend: the senior people who built Tesla's vision-only paradigm are increasingly distributed across the AI industry, while Tesla's own approach is being publicly tested as it tries to scale Robotaxi and bring FSD to more European markets through the subscription model that Tesla previewed earlier this year. The technical lineage is still Tesla's; the talent map has changed.
