One Gateway for Every LLM

LLM Gateway is a unified entry point for large language models. Route requests across providers through a single API, with built-in caching, rate limiting, cost control, security, and full observability.

Everything You Need to Run LLMs in Production

Ship AI features faster while staying in control of cost, security, and reliability.

Multi-Provider Routing

Route to any model from any provider through one OpenAI-compatible API. Switch or A/B models without touching your code.

Automatic Failover

Health-checked fallbacks and retries keep your app running even when a provider is degraded or rate-limited.

Semantic Caching

Cache responses to cut latency and spend. Configurable TTLs and cache keys per route.

Rate & Quota Limits

Per-key, per-team, and per-model rate limits and budgets to prevent runaway usage.

Cost Control

Real-time token accounting and spend tracking across every model, key, and project.

Security & Guardrails

Central key vault, PII redaction, and prompt/response policies keep sensitive data safe.

Full Observability

Logs, traces, latency, and quality metrics for every request in one dashboard.

Load Balancing

Distribute traffic across keys and regions to maximize throughput and availability.

Drop-in Integration

OpenAI-compatible endpoints — point your existing SDK at the gateway and go.

A Single API in Front of Your Whole Model Stack

Your applications talk to one endpoint. The gateway authenticates, applies policies, picks the best model, caches when possible, and streams the response back — while recording every metric.

  • Send a request
    Your app calls the gateway with a standard, OpenAI-compatible request.
  • Route & protect
    The gateway authenticates, applies rate limits and guardrails, and selects the model.
  • Serve & observe
    Responses are cached, streamed back, and every token is logged for cost and quality.
