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.

How to use GLM (Z.ai) safely

  • Use the business variant and sign a data processing agreement (DPA).
  • Do not enter unnecessary personal data into prompts; anonymise where possible.
  • Ask the provider explicitly where data is stored and processed.
  • Keep a professional in the loop: with AI imagery, watch two things: rights and data.

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

What should I watch out for with AI in graphic design & design?
With AI imagery, pay attention to two things: rights and data. Rights: with Recraft, images from the free plan of Recraft itself are not for commercial use, and only paid plans give you full ownership. Adobe says it trains Firefly models on licensed material and public domain content, not on user content. Data: with Kittl, training on your content is switched on by default in the Starter and Professional plans (the administrator can turn it off), while in Organization and Enterprise it is off. CELUM (Berlin) states in the privacy statement that data is also processed outside Europe, including in Canada and the US. If you want to keep your brand files in the EU: Frontify offers hosting in Frankfurt, Bynder on AWS Frankfurt and Figma on Azure in the EU. Penpot can be self-hosted. Do not upload client material under NDA to a free account, and record in your quote whether and how you use AI.
