LLM Gateway overview

LLM Gateway centralizes control across enterprise LLM and API traffic in your organization. It gives you visibility, policy enforcement, and identity-aware routing with minimal latency overhead, including:

Production-ready support for enterprise workloads
Cost and latency-aware routing across model providers
Inline request inspection and data redaction
Full observability and policy-based enforcement

Understanding LLM Gateway

Managing API consumption at scale is complex, especially if you are making high volumes of calls, consuming APIs on behalf of your clients, using unreliable APIs, or sharing quotas between environments.

LLM Gateway resolves these operational bottlenecks through a real-time API consumption management architecture that processes outbound traffic, integrating directly into established infrastructure with zero code modifications.

LLM Gateway capabilities and advantages

Scaled infrastructure increases the complexity of API consumption management. API providers issue 429 (Too Many Requests) responses when inbound requests exceed configured rate thresholds. LLM Gateway delivers centralized rate-limit and quota execution to control API traffic and limit threshold violations.

Key capabilities include:

Unify the management of third-party API consumption in production.
Diagnose and fix API performance issues in real time.
Create resilience with new and customizable Gateway policies.

LLM Gateway provides immediate support across third-party APIs and optimizes outbound network flows without latency degradation.

Who uses LLM Gateway

LLM Gateway supports organizations that face complex challenges in managing API quotas and rate limits, especially when multiple services need to interact with the same API provider. These challenges often stem from a lack of centralized state or awareness among services, leading to bottlenecks and inefficient API usage. Timing is critical, which is why organizations need a solution that can prioritize quotas and scale effectively.

LLM Gateway API consumption management

LLM Gateway optimizes and manages API traffic using out-of-the-box configurations called LLM Gateway policies, which provide detailed control over requests and responses, optimizing traffic management during peaks and unexpected surges. Whether you deploy in siloed environments or use a shared-state configuration, LLM Gateway supports seamless installation across departments and infrastructures. Its Failsafe mechanism ensures no data loss or service disruption by rerouting traffic during timeouts. The gateway's scalability and performance remain consistent, providing minimal latency while balancing even the most intensive API workloads across various architectures and cloud providers.

LLM Gateway policies

LLM Gateway Gateway policies are the core of the API Management system, enabling you to enforce API consumption policies with precision. Gateway policies are YAML-based configurations that define how API requests and responses are processed in real time. You can customize and optimize traffic across multiple environments with ease, ensuring efficient API usage.

The following policies are available:

LLM Gateway quota management

LLM Gateway quotas offer a flexible, centralized way to manage API consumption, supporting both internal and provider-defined quotas. You can set precise limits for API consumption across various policies and user groups, ensuring real-time, scalable control of API usage and preventing overconsumption of resources.

Key quota functions include:

Monitor real-time API usage: Quotas update dynamically, giving you accurate, up-to-the-minute usage data.
Granular control: Set quotas based on URLs, headers, or user groups for detailed resource control.
Scalability: Manage and track quotas across multiple API Gateway policies and environments, ensuring smooth traffic management.

For more information, refer to Configuring API quotas.
