What is LLM Gateway?
A proxy layer between your application and LLM providers that adds routing, caching, and cost controls.
An LLM gateway is a middleware layer that sits between your application and one or more LLM providers. It intercepts API calls, applies transformations (compression, routing, caching), enforces policies (rate limits, budget caps), and logs usage data.
The key benefit of a gateway is that it decouples your application from specific LLM providers. You point your code at the gateway endpoint instead of directly at OpenAI or Anthropic — the gateway handles provider selection, failover, and optimization transparently.
GateCtr is an AI Cost Infrastructure layer — a gateway focused specifically on cost reduction. It combines prompt compression, intelligent routing, and hard budget enforcement in a single endpoint swap with no code changes required.
GateCtr addresses llm gateway automatically on every API call — no configuration required. The results are visible in real-time in the GateCtr dashboard, with per-request breakdowns of tokens, cost, and savings.
