Regional Data Residency

Relai operates in two fully isolated regions: EU and US. Your prompts and completions never leave your chosen region, and are never exposed to frontier AI labs.

Available Regions

Private Cloud Infrastructure

All inference runs on Amazon Bedrock and Azure OpenAI — enterprise private cloud deployments where frontier AI labs cannot access your data:

• Zero training on your data — Anthropic, OpenAI, and other frontier labs never see your prompts or use them for training
• No logging by model providers — Your conversations are not stored or analyzed by AI companies
• Contractual guarantees — DPAs with AWS and Microsoft, not with frontier labs who may change policies
• Enterprise compliance — SOC2, HIPAA, and ISO 27001 certifications from cloud providers

How It Works

When you make an API request to an EU endpoint:

1. Your request arrives at our EU gateway (Frankfurt)
2. We route to EU-hosted Bedrock or Azure OpenAI deployments
3. The response returns directly to you
4. No data crosses to the US region or to AI lab servers

┌─────────────┐     ┌─────────────┐     ┌─────────────────────┐

│   (EU)      │◀────│  (Frankfurt)│◀────│  (Private Cloud)    │
└─────────────┘     └─────────────┘     └─────────────────────┘

                    ❌ Never touches Anthropic/OpenAI servers

API Key Regions

Each API key is bound to a region when created:

• rk-eu-... — EU region key
• rk-us-... — US region key

Using a key on the wrong region's endpoint returns an error:

{
  "error": {
    "message": "API key is for region EU, but request was made to US",
    "type": "region_mismatch",
    "code": 403
  }
}

GDPR Compliance

For EU customers processing personal data:

• Data Processing Agreement (DPA): Available on request, covering AWS and Azure sub-processors
• Sub-processors: Only AWS and Microsoft — no frontier AI labs in the data processing chain
• Data Retention: Prompts and completions are never stored (zero-retention policy)
• Article 28 compliance: Full controller-processor documentation available

Multi-Region Setup

For global applications, create separate API keys per region:

const euClient = new OpenAI({
  apiKey: process.env.RELAI_EU_KEY,
  baseURL: "https://eu.api.llmrelai.com/v1",
});

const usClient = new OpenAI({
  apiKey: process.env.RELAI_US_KEY,
  baseURL: "https://us.api.llmrelai.com/v1",
});

// Route based on user location
const client = userRegion === "EU" ? euClient : usClient;

Dashboard Region

Your dashboard account is region-specific:

• EU users: app.llmrelai.com (default)
• US users: us.app.llmrelai.com (coming soon)

Each region has isolated:

• User accounts
• Organizations
• API keys
• Billing
• Usage data
