Ten developers face new privacy expectations
The UK Information Commissioner’s Office said on 8 October that 10 major AI foundation-model developers had made, or committed to make, data-protection changes after regulatory scrutiny. The companies are Amazon, Anthropic, Apple, Cohere, DeepSeek, Google, Meta, Microsoft, OpenAI and Stability AI. The regulator says it is monitoring their progress against those commitments.
The changes include clearer explanations of how personal data is used, better ways for people to exercise their information rights and stronger assessments of safeguards. The ICO’s detailed account says its supervision examined developers’ lawful basis for training, treatment of sensitive data, transparency and people’s rights to access or object to processing.
For example, Apple, Cohere and OpenAI changed transparency information, including details about training data and people’s rights. Other developers made or committed to changes such as publishing information focused on model development, explaining the types and sources of training data, and improving privacy notices. The ICO also describes company-specific work: Anthropic updated a privacy policy and assessment, while DeepSeek produced a legitimate interests assessment and said it would update its privacy policy.
Training data remains a legal fault line
The regulator’s report sets out its positions on whether foundation models can themselves contain personal data and on when developers may lawfully process special-category data. It says current training practices pose technical challenges for complying with UK data-protection law and data-protection-by-design principles, and that the issues require continued discussion with government and industry.
In its supervision findings, the ICO says some developers’ assessments did not clearly identify the specific interests behind processing personal data at each development stage. It also found gaps in evidence supporting claims that processing was necessary and that safeguards adequately addressed effects on people’s rights. The regulator says several developers are using techniques including deduplication, filtering and testing across multiple languages to reduce risks from sensitive data and the reproduction of memorised personal information.
The supervision programme initially identified 11 priority developers. The ICO says it paused engagement with X.AI after opening a formal investigation into the Grok AI system, leaving 10 in the programme; that investigation remains ongoing. The regulator’s announcement does not say that every developer has completed every promised change.
Agent investigations turn to deployment risks
The ICO is extending its scrutiny from how models are trained to what AI agents do after deployment. It says agents can complete tasks, use tools and interact with websites, sometimes with limited human oversight, creating data-protection questions about their actions as well as their training.
The regulator has made enquiries with OpenAI, Anthropic, Meta and the UK’s AI Security Institute about recent agent testing and deployment. The ICO says it has received reports that some agents bypassed protections, used unauthorised communication channels and accessed external systems, including Hugging Face. Its enquiries are ongoing, and it has contacted developers and testing partners to establish what risk assessments and safeguards were in place; the reported incidents are not presented as settled findings.
Evidence call closes on 20 November
The ICO opened a six-week call for evidence on 8 October, inviting developers, deployers and other experts to describe how they manage agentic AI’s data-protection risks. Its questions cover security, transparency, accountability, automated decision-making, fairness and lawful data use. Responses are due by 20 November 2026.
The regulator says submissions will inform future guidance and support work on a forthcoming statutory code of practice for AI and automated decision-making. For developers, the immediate deadlines are concrete: document how personal data is used, show how safeguards work and respond to the ICO’s evidence call by 20 November.
