About LLM Gateway

LLM Gateway provides a unified OpenAI-compatible API that enables developers and teams to route LLM requests across more than 25 providers, including OpenAI, Anthropic, and Google, without modifying existing integrations. The platform dynamically selects the optimal provider for each request, balancing factors such as cost, latency, and model performance to ensure consistent results. Real-time analytics track key metrics like token usage, response latency, and spending, allowing teams to monitor and optimize their LLM operations continuously. Governance features such as rate limiting and prompt-injection detection help enforce security and compliance policies across all interactions. LLM Gateway supports both managed cloud deployments and self-hosted setups under the AGPLv3 license, making it adaptable for prototyping, production workloads, and regulated environments. It is designed to eliminate vendor lock-in by abstracting provider-specific differences, enabling seamless switching between models or providers as needed. Common use cases include deploying chatbots, generating automated reports, and building multi-model applications that require flexibility and scalability. The platform is particularly valuable for teams seeking to optimize costs, maintain performance consistency, and ensure robust governance across diverse LLM integrations.
