His expertise is invaluable in shedding light on the societal and philosophical issues surrounding the rapid development of AI. He actively contributes to the public debate on the impact of AI on our societies and the need for an ethical framework.
A former Secretary of State for the Digital Economy, Cédric O played a key role in driving France's national strategy for artificial intelligence.

An expert in AI and LLM (Large Language Models) can have several roles: researcher, developer, consultant, entrepreneur or ethicist. Their role is to understand, design, train, deploy and optimise artificial intelligence systems, particularly language models capable of generating text, translating, summarising or answering complex questions, while analysing their technical and societal implications.
AI and LLM are transforming businesses in France by automating repetitive tasks, improving the customer experience (chatbots, virtual assistants), optimising processes (data analysis, prediction), personalising offerings, and enabling the creation of innovative new products and services. They increase productivity, competitiveness and capacity for innovation.
The choice depends on your needs and your in-house resources. An independent expert can offer in-depth, customised expertise for specific projects. A specialist agency has a multidisciplinary team capable of managing complex projects, from strategic advice to technical implementation and ongoing optimisation of AI solutions.
The main applications of LLM for businesses include: content generation (marketing copywriting, reports), improving customer service (intelligent chatbots), semantic analysis and natural language understanding, machine translation, personalising interactions, and optimising internal or external search (such as Google's AI Overviews).
France is positioning itself as a major player in global AI, thanks to its internationally renowned researchers (such as Yann LeCun), the creation of innovative start-ups (such as Mistral AI and Hugging Face), public investment in research, and a dynamic ecosystem that fosters collaboration between academia and industry. The issue of AI ethics is also a major concern in France.
Ethical challenges include the protection of personal data, algorithmic biases (which can lead to discrimination), the transparency of AI decisions, liability in the event of error or damage, the impact on employment, and the issue of monitoring and controlling autonomous systems. Experts such as Jean-Gabriel Ganascia are actively working on these issues.
AI and LLM experts, particularly those with SEO backgrounds such as Frédéric Poulet, can help optimise online visibility by understanding how Google's AI algorithms interpret and rank content. They advise on creating semantically rich content, optimising for AI Overviews and understanding complex search intent to align with LLM expectations.
To become an AI and LLM expert in France, there are a number of options: masters degrees specialising in Artificial Intelligence, Machine Learning and Data Science at universities (e.g. Sorbonne, Paris-Saclay) and leading engineering schools (e.g. Polytechnique, CentraleSupélec), research doctorates, as well as continuing education courses and specialist bootcamps for professionals.
Yes, open source plays a very important role, as demonstrated by the success of Hugging Face and the Mistral AI approach. Open source fosters collaboration, rapid innovation, transparency and democratisation of access to AI models. This enables a wider community to contribute to the development and improvement of LLMs.
AI and LLM can have a dual impact on employment. On the one hand, they can automate certain repetitive tasks, leading to the disappearance of certain professions. On the other hand, they are creating new jobs (AI specialists, prompt engineers, AI ethicists) and transforming existing roles, requiring workers to upgrade their skills and adapt.
