overview

What is Kong AI Gateway?

Kong AI Gateway is an AI gateway tool developed by Kong that enables organizations utilizing Kong's API management ecosystem to manage, secure, and optimize traffic to Large Language Models (LLMs) and AI agents. It extends Kong's enterprise API management platform with LLM-specific capabilities such as prompt compression, semantic caching, and dynamic model routing. This solution integrates LLM routing and governance into a broader, enterprise-grade API management framework, acting as a high-performance control plane between applications and AI models. It provides robust API management, access control, and policy enforcement specifically for LLM traffic, including strong token compression features and robust routing and fallback mechanisms. The gateway is designed for organizations already utilizing Kong's API management ecosystem to unify control over both traditional APIs and AI services.

features

Key Features of Kong AI Gateway

Kong AI Gateway provides a comprehensive set of features designed to manage, secure, and optimize AI workloads within an enterprise API management framework.

  • LLM Orchestration and Dynamic Routing: Simplifies integrating various AI models from multiple providers, routing requests based on cost, performance, or availability, with load balancing and fallback.
  • AI Traffic Governance and Security: Enforces governance on outgoing AI prompts via allow/deny lists, PII sanitization across 20 categories and 9 languages, content safety guardrails, and audit logging.
  • Cost Management and Observability: Implements token-based throttling for usage quotas (prompt, response, total tokens) and provides real-time analytics integrating with OpenTelemetry and Prometheus.
  • Prompt Engineering and Optimization: Features AI RAG Injector for automated Retrieval-Augmented Generation workflows, prompt compression, and prompt engineering templates.
  • Agentic AI Workload Management: The Kong Agent Gateway capability (introduced April 2026 in AI Gateway 3.14) governs LLM, Multi-Agent Communication Protocol (MCP), and agent-to-agent (A2A) communication.
  • Semantic Caching: Optimizes performance and reduces costs by caching responses to semantically similar prompts.
  • Robust API Management: Extends Kong's enterprise API management platform to include access control and policy enforcement for LLM traffic.
  • Strong Token Compression: Reduces data transfer and processing overhead for AI interactions.

use cases

Who Should Use Kong AI Gateway?

  • Teams needing to manage AI connectivity, governance, security, and cost control for diverse AI models and providers.
  • Developers and operations teams looking to orchestrate and optimize LLM interactions, including prompt engineering and RAG workflows.
  • Companies managing complex agentic AI workloads, including Multi-Agent Communication Protocol (MCP) and agent-to-agent (A2A) communication.

how to use

How to Use Kong AI Gateway

Kong AI Gateway is deployed as an extension of an existing Kong Gateway instance, providing a unified control plane for both traditional APIs and AI services. Initial setup involves integrating the AI Gateway into the Kong Konnect platform.

  • 1Deploy Kong AI Gateway within an existing Kong Gateway or Kong Konnect environment.
  • 2Configure routes to direct application requests to specific Large Language Models (LLMs) or AI agents from various providers.
  • 3Implement governance policies, including access control, PII sanitization, and content safety guardrails, for AI traffic.
  • 4Apply token-based throttling and cost management rules to control LLM usage and expenditures.
  • 5Utilize prompt engineering features like AI RAG Injector and prompt compression to optimize LLM interactions.
  • 6Monitor AI traffic, model performance, and security events through integrated observability tools like OpenTelemetry and Prometheus.

Kong AI Gateway vs Competitors

Kong AI Gateway is positioned as a comprehensive API + AI platform that unifies API and AI governance, supporting hybrid and multi-cloud environments. Its core advantage lies in extending a proven API platform into the AI era.

1
Bifrost (by Maxim AI)↗

An open-source, Go-based AI gateway designed for mission-critical enterprise AI workloads, offering microsecond-level performance and comprehensive governance.

Unlike Kong AI Gateway which extends an existing API management platform, Bifrost is an AI-native open-source gateway built from the ground up for LLM and agent workloads, focusing on ultra-low latency and flexible deployment options like in-VPC or air-gapped.

2
TrueFoundry AI PlatformOn StorkCompare

A unified enterprise AI platform offering robust governance and control over both proprietary and open-source models, with strong compliance features and hybrid/VPC/air-gapped deployment options.

While Kong AI Gateway integrates LLM governance into an existing API management framework, TrueFoundry provides a broader, unified enterprise AI platform that includes LLM, MCP, and Agent Gateway capabilities, with a strong emphasis on secure deployments in private and regulated environments.

3
Portkey AI GatewayOn StorkCompare

Provides a unified API layer for accessing a vast catalog of LLMs and providers, with a strong focus on reliability, observability, caching, retries, and fallbacks.

Portkey offers strong AI routing and analytics with features like semantic caching and automatic retries, but it is more focused on the AI interaction layer and does not cover broader API lifecycle management as comprehensively as Kong's full API management platform.

4
Axway Amplify AI Gateway↗

A centralized control plane that integrates with Axway's existing API management platforms to provide secure, governed, and orchestrated interactions with AI and LLM services.

Similar to Kong AI Gateway, Axway Amplify AI Gateway extends an existing enterprise API management ecosystem (Amplify Fusion and Amplify Engage) to include AI-specific governance and orchestration, offering a comprehensive solution for organizations already invested in the Axway platform.
