The AI infrastructure layer

The control plane for AI traffic.

Relay sits between your application and every LLM provider. It routes intelligently, fails over automatically, monitors continuously, and optimizes spend — without you writing the plumbing.

What Relay does

Infrastructure, not a wrapper.

Six capabilities that turn LLM integrations into a managed, observable, governed system.

Unified API
One API, every model

OpenAI-compatible interface across 100+ models from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek, Bedrock, Azure, Groq, Together and more.

Routing engine
Intelligent routing

Send each request to the optimal model based on task, cost, latency, region, or your own policies. Automatic failover when a provider degrades.

Observability
Production-grade tracing

Every request traced end-to-end: prompt, response, tokens, latency, fallback chain, cost. Prompt observability built in.

Reliability
Failovers that work

Retry policies, circuit breakers, region awareness, and provider reliability scoring so AI never goes down with one vendor.

Cost intelligence
AI spend under control

Per-key, per-team, per-model budgets, alerts, and rate limits. Live cost forecasting across providers.

Governance
Enterprise from day one

SSO, SAML, audit logs, RBAC, data residency, PII redaction, and policy enforcement at the gateway.

How it works

A single gateway between your app and every provider.

Change one base URL. Keep your existing OpenAI SDK. Get routing, fallbacks, governance, and observability immediately — without rebuilding anything.

  • Drop-in OpenAI compatibility
