AI MODEL DISCLOSURE

Last Updated: January 2025

This page provides detailed information about the artificial intelligence systems, models, and technologies we use to power Hamhey's student relocation services.

1. Large Language Models (LLMs)

• Primary Models: OpenAI GPT-4, GPT-3.5-turbo (via API integration)
• Purpose: Chat assistance, query understanding, content generation, translation
• Provider: OpenAI LP (San Francisco, CA, USA)

2. Recommendation Algorithms

• Technology: Custom machine learning models for housing recommendations
• Purpose: Personalized property matching based on preferences and budget
• Training: Proprietary models trained on anonymized user interaction data

3. Fraud Detection Systems

• Technology: Anomaly detection and pattern recognition algorithms
• Purpose: Identify fraudulent listings, fake profiles, and scam attempts
• Provider: Stripe Radar (for payment fraud) + internal ML models

What Data We Use

• User Interaction Data: Chat queries, property searches, booking patterns (anonymized for ML training)
• Property Information: Listings, descriptions, pricing, availability (used to train recommendation systems)
• Public Information: University data, visa requirements, city guides (used for knowledge enhancement)

What We DON'T Use

We continuously monitor and report on AI system performance:

• Hallucinations: LLMs may occasionally generate plausible-sounding but incorrect information
• Context Limitations: AI may not fully understand complex, nuanced situations requiring human judgment
• Language Constraints: Performance varies across languages; English responses are most accurate
• Legal/Medical Limitations: AI cannot provide legal advice, medical guidance, or official visa determinations
• Real-Time Data Gaps: AI knowledge has cutoff dates and may not reflect the most recent policy changes

We use the following third-party AI services, all of which comply with GDPR and international data protection standards:

• Right to Human Review: You can request human review of any AI-generated decision affecting your account
• Right to Opt-Out: You can disable AI chat features and request human-only support
• Right to Explanation: You can request an explanation of how AI recommendations or decisions were made
• Right to Data Exclusion: You can opt out of having your data used for AI model improvement

We regularly update our AI systems to improve performance and safety. Significant changes are announced via:

• Email notifications to registered users
• In-app announcements for major model upgrades
• Updates to this disclosure page (with version history)
• Monthly transparency reports (available on our blog)
