Foundational Models
We host pre‑trained foundation models in Azure AI Foundry. These models are managed by Microsoft within Azure’s secure environment but may originate from various third‑party providers (OpenAI, Hugging Face, Meta, etc.).
No Student Data Used for Training
Lessi AI never uses student or teacher interaction data to train, fine‑tune, or improve any large language model. Prompts and responses are processed in real time and are not retained or repurposed for model training.
Data Isolation & Ownership
All data remains within Lessi's Azure environment. Microsoft’s Azure OpenAI Service does not share your content with external model providers; all data remains within your control and is processed in the United States.
Encryption & Security Controls
Lessi encrypts all data both in transit (TLS/SSL) and at rest (AES‑256). Keys are managed in Azure Key Vault, and network isolation is enforced via Azure Private Link. Lessi AI’s access is governed by Azure Active Directory and role‑based access control (RBAC).
Auditability & Traceability
Azure Monitor and built‑in audit logs capture every access and modification event. Detailed traceability ensures accountability in data processing and supports FERPA’s right to review and amend records.
