Yann LeCun, Meta’s chief AI scientist and renowned French-American computer scientist, delivered a stark warning to European policymakers at the AI Action Summit in Paris on Monday: restricting open-source artificial intelligence models would be a “huge mistake” that could leave Europe trailing behind global competitors.
LeCun’s comments come amid ongoing debates about AI regulation in Europe, particularly concerning the European Union’s Artificial Intelligence Act approved in 2024. He argued that some European countries are attempting to make open-source AI models illegal in an effort to maintain advantages over political rivals, but this approach is fundamentally flawed. “When you do research in secret, you fall behind,” LeCun emphasized. “The rest of the world will go open source and will overtake you. That’s currently what’s happening.”
The timing of LeCun’s remarks is particularly significant following the late-January release of DeepSeek’s R1 model, an open-source AI system from an emerging Chinese startup that sent shockwaves through the US tech industry. Third-party testing demonstrated that DeepSeek’s model outperformed competitors from OpenAI, Meta, and other leading developers, despite being built with significantly less funding. The model’s open-source nature allows anyone to download and build upon it freely.
Open-source AI models enable the free and open sharing of software code to anyone for any purpose, a philosophy LeCun has championed throughout his career. He has consistently argued that these powerful systems should not be controlled by a small number of companies or individuals. Meta’s own AI models, called Llama, are mostly open-source, reflecting LeCun’s influence within the company. This stands in contrast to OpenAI, which despite being originally founded as an open-source organization, has shifted toward closed-source models in recent years.
LeCun noted that DeepSeek benefited from open research and open-source tools, including PyTorch and Llama from Meta, demonstrating how collaborative development accelerates innovation. “They came up with new ideas and built them on top of other people’s work,” he wrote in a January Threads post.
European AI startups including French company Mistral and Germany’s Aleph Alpha have also criticized European regulatory proposals targeting foundational model makers. Legislators in France, Germany, and Italy have advocated for self-regulation frameworks that would allow European AI companies to compete more effectively with US tech giants, rather than imposing restrictive regulations that could stifle innovation and competitiveness in the global AI race.

When you do research in secret, you fall behind. The rest of the world will go open source and will overtake you. That’s currently what’s happening.
Yann LeCun, Meta’s chief AI scientist, made this statement at the AI Action Summit in Paris, warning European policymakers that restrictive approaches to AI development would result in Europe losing ground to competitors who embrace open-source collaboration.
We cannot afford to have those systems come from a handful of companies from the West Coast of the US or China.
LeCun emphasized the importance of democratizing AI development beyond a small number of dominant players, arguing that open-source models prevent dangerous concentration of AI capabilities in the hands of few companies or nations.
DeepSeek has profited from open research and open source (e.g. PyTorch and Llama from Meta). They came up with new ideas and built them on top of other people’s work.
In a January Threads post, LeCun highlighted how China’s DeepSeek leveraged open-source tools to achieve breakthrough results, demonstrating how collaborative development accelerates innovation and allows newcomers to compete with established players.
Our Take
LeCun’s intervention represents more than technical advocacy—it’s a geopolitical warning about Europe’s AI future. The DeepSeek moment proved that open-source collaboration can level the playing field, allowing resource-constrained innovators to challenge well-funded incumbents. Europe’s regulatory instinct, while understandable given legitimate AI safety concerns, risks creating a self-fulfilling prophecy of technological dependence.
The irony is palpable: regulations intended to protect European interests may guarantee their erosion. As the US and China race ahead with different approaches—one driven by massive private investment, the other by state coordination—Europe’s window for establishing AI sovereignty narrows. LeCun’s position reflects Meta’s strategic interests in open-source, but his core argument transcends corporate advocacy. History suggests that closed, protectionist approaches to transformative technologies rarely succeed. Europe must find regulatory frameworks that protect citizens without handicapping innovation, a delicate balance that will define its technological relevance in the coming decades.
Why This Matters
This debate represents a critical crossroads for Europe’s AI competitiveness and the future of global AI development. LeCun’s warning highlights the tension between regulatory caution and innovation velocity in the rapidly evolving AI landscape. As China demonstrates breakthrough capabilities with DeepSeek’s cost-effective, open-source model, European policymakers face pressure to avoid regulations that could handicap their domestic AI industry.
The open-source versus closed-source debate has profound implications for AI democratization, innovation speed, and market concentration. Open-source models enable smaller companies, researchers, and developers worldwide to participate in AI advancement without massive capital requirements. This could prevent AI capabilities from being monopolized by a handful of well-funded Western or Chinese companies.
For businesses and workers, the regulatory approach Europe adopts will determine whether European companies can compete globally or become dependent on AI systems developed elsewhere. The EU’s Artificial Intelligence Act aims to mitigate risks from powerful AI technology, but overly restrictive measures could inadvertently ensure the very outcome they seek to prevent: European technological dependence and diminished influence in shaping AI’s future. This moment will likely define Europe’s role in the AI era for decades to come.
