Why It Matters for AI Governance
Fine-tuning with personal data creates permanent compliance obligations. If customer data is used for fine-tuning, it becomes embedded in model weights and cannot be easily removed, making right-to-erasure requests extremely difficult.
How CrewCheck Handles This
CrewCheck's LLM gateway applies fine-tuning-related controls at the request boundary. Every AI call passes through detection, policy evaluation, and audit logging — ensuring that fine-tuning is addressed consistently across all teams and providers.
The governance dashboard provides real-time visibility into fine-tuning events, with drill-down capabilities for compliance officers and exportable evidence for auditors.
