L'Oréal rolls out internal GPT to 90,000 employees
In a podcast interview, L'Oréal's DACH CIO Arooj Humayun detailed the company's three-stage plan for integrating generative AI across its 90,000 employees. The plan includes awareness building, training, and tool deployment. To ensure data privacy and compliance with stringent German regulations, L'Oréal developed its own internal platform, L'Oréal GPT, which runs on-premise and uses vetted large language models. This prevents any data from leaving the company. Additionally, they use a tool called CreateTech for image generation. The company is now moving towards AI agents, dubbed 'Companions', which can execute actions like booking travel. Usage is measured via anonymized prompt counts. The initiative aims to empower employees in various departments, including finance, HR, and marketing, to automate repetitive tasks.

OpenAI Taps Criteo to Add Programmatic Ads in ChatGPT
OpenAI has named Criteo its first ad tech partner, integrating Criteo’s programmatic network into an ad pilot inside ChatGPT.

OpenAI reportedly seeks a minimum brand commitment of $200,000 to participate, while Criteo cites internal data showing LLM-sourced traffic converts 1.5× better than other referral channels. The pilot already includes major agency clients such as WPP, Omnicom and Dentsu.
