What should I look out for with AI in procurement & tendering?

Quotes, prices, contracts and submissions are commercially confidential; supplier and contact details also contain personal data. Sign a data processing agreement, ask where the data is stored (EU hosting) and which AI sub-processors are used, and get it recorded that your bids and spend data are not used to train models. Never paste confidential documents from an ongoing tender into a free chatbot. In public procurement, the Dutch Public Procurement Act and the principles of equal treatment and transparency apply: do not let AI award or exclude on its own, and explain how an assessment was reached. If you as a public body procure AI yourself, use the PIANOo guideline 'Buying or having algorithms and AI developed' and take the AI Act into account. An AI-generated submission remains your responsibility: check every commitment.

5 November 2026Flaw in Lockdown Mode patched

Via pop-up windows in the HTML preview of code blocks, an attacker could bypass Lockdown Mode and siphon off your chat history, via a manipulated prompt, GPT or shared chat.

1 November 2026Reports to the police and stricter rules for teens

In the third quarter of 2026, OpenAI made more than 200 reports to law enforcement about threatened violence based on ChatGPT conversations. Conversations in which someone appears fixated on violence may be ended automatically by ChatGPT, and if it happens repeatedly, OpenAI can pause the account. So don't assume that what you type into ChatGPT stays confidential. source

27 October 2026Connection with iCloud Mail and Calendar on all subscriptions

ChatGPT can use plugins to search and summarise iCloud mail and change appointments, including on the free subscription. Signing in uses an app-specific password from Apple; it remains valid if you disconnect the integration in ChatGPT and you must revoke it yourself via account.apple.com. source
