What should I look out for with AI in corporate training & L&D?

Learning platforms process employees' personal data: progress, assessment results, recordings of role-plays and sometimes evaluations. Sign a data processing agreement, ask where the data is stored and which language models and sub-processors sit behind it (often OpenAI or Azure OpenAI), and insist that your course material and learning data are not used to train models. Do not upload confidential company information to a free chatbot to build a course from it. If you use an AI avatar or a cloned voice of a real colleague, record written consent. Do not let AI independently assess or select employees for roles: AI systems that influence decisions about workers or access to training can be high-risk under the EU AI Act, and AI literacy for staff has been mandatory since February 2025. Check AI-generated course content for factual errors before you publish it.

Latest developments

26 October 2026Cloudflare Workers AI: GLM-5.3 leaked 155 answers between customers

Cloudflare reported that GLM-5.3 on Workers AI (@cf/zai-org/glm-5.3) returned data from other customers' requests in 27 answers between 9 August and 2026 September 155. Only prompts above 681,280 tokens were affected; the cause was a KV cache that was too small in the hosting configuration, not the model itself. Cloudflare found no evidence of misuse and fixed it on 9 September. If you used very long prompts containing personal data via Workers AI in that period, assess whether a data breach has occurred. source
