ProfileFoundry: A Synthetic Person-Object Substrate for Privacy, Memory, and Tool-Use Evaluation in LLM Agent
arXiv:2606.26403v1 Announce Type: new Abstract: Foundation-model research increasingly needs data about people: user state, personal histories, relationships, contact-like fields, documents, and longitudinal updates. Real user data is difficult to share, perturb, audit, or redistribute responsibly, while independently generated fake fields rarely preserve the cross-field and temporal consistency needed for controlled evaluation. We present PROFILEFOUNDRY, a deterministic generator and fixed reference release of 100,000 adult synthetic Person Objects across eight locales. Each object combines a
Foundation model research increasingly demands realistic personal data for evaluation, and traditional sources pose significant privacy and consistency challenges.
This development offers a controlled, scalable, and privacy-preserving method to train and evaluate advanced AI agents, addressing a critical bottleneck in their development.
The ability to generate consistent and audit-friendly synthetic data removes a major hurdle for responsible AI development and allows for more robust testing of personalization and memory in LLMs.
