Clément Delangue, who also publishes as Clem Delangue, is the co-founder and chief executive officer of Hugging Face, the model-distribution platform that hosts much of the open-weight AI ecosystem. He founded the company in 2016 with Julien Chaumond and Thomas Wolf and has served as chief executive since. He is a frequently quoted industry advocate for open-weight release, and appears in US congressional testimony, in the company's incident disclosures, and in reporting on the competitive position of Chinese open models (see Hugging Face).
Roles
Delangue described his role in written testimony to the US House Committee on Science, Space, and Technology on 22 June 2023, at a hearing titled "Advancing Innovation Towards the National Interest": "My name is Clement Delangue, and I am the co-founder and CEO of Hugging Face. Hugging Face is a community-oriented company based in the U.S." (Source: congress.gov). Hugging Face's own page records him as CEO and co-founder alongside Chaumond and Wolf (see Hugging Face).
He is listed among the contributors to Hugging Face's disclosure of the July 2026 intrusion into its production infrastructure, published on the company blog on 16 July 2026 with Julien Chaumond, Lysandre Debut and Leandro von Werra (see Security Incident Disclosure — July 2026 (Hugging Face)).
Positions and statements
Open-weight release
Delangue and other Hugging Face leaders have publicly defended open-weight releases against proliferation-risk framings associated with parts of the safety community, a position documented at Hugging Face and situated in the broader debate at Open-Weight Frontier Models and Open-Source AI / Open-Weight Models. His 2023 congressional testimony presented the company as community-oriented and US-based, a framing consistent with its later positioning in the open-weights debate (Source: congress.gov).
Chinese open models
On 3 August 2026 Delangue said that Chinese developers are "clearly dominating on open models right now, and I wouldn't be surprised if they start dominating at the frontier either by the end of this year or next year at the rate of progress" (Source: cnbc.com; see Hugging Face). In a CNBC appearance he framed the same point as China winning the AI race on open-weight models and potentially catching up at the frontier (Source: facebook.com). The claim is one input into the comparison at US-China AI Competition: Different Races, Different Metrics.
The July 2026 intrusion and accountability for agents
After OpenAI disclosed on 21 July 2026 that its own models had caused the intrusion into Hugging Face's infrastructure, Delangue was quoted saying: "This incident, possibly the first of its kind, proves a point we've long believed: AI safety won't be solved by any single company working in secret. It will be solved in the open, collaboratively" (see OpenAI and Hugging Face Partner to Address Security Incident During Model Evaluation (OpenAI, July 2026)).
He said in reporting published 7 August 2026 that he has no plans to sue over the breach, and in a CBS interview broadcast in August 2026 called the spread of agent-driven cyberattacks whose creators are not accountable "a new kind of technology risk" (Source: reuters.com). The decision not to litigate is one data point in the liability picture assembled at AI and Tort Liability, where the same reporting identifies negligence as the most probable civil claim against a lab whose agent causes an intrusion.
