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

Does GLM (Z.ai) train on my data?
The international service Z.ai runs through JINGSHENG HENGXING TECHNOLOGY PTE. LTD. (Singapore); personal data is in principle processed in Singapore. According to the data processing agreement, API content is processed in real time and not stored. GLM-5.2 is open-weight under MIT and can therefore be fully self-hosted or hosted through an EU provider.
What should I watch out for with AI in temp staffing & flexible work?
Candidate profiles, job applications and assessments are personal data under the GDPR. Automated matching and selection fall under the AI Act (high risk for decisions about access to work): be transparent and keep a human in the loop. Never send CAO-sensitive payroll or BSN (citizen service number) data to a consumer version of a chatbot. Check whether AI matching models introduce unintended discrimination (age, origin, gender) and record audits.
