Top 7 Enterprise AI Gateways I Wish I Knew Before I Deployed One
An AI gateway can look like a simple layer between your application and an AI model, until you actually deploy one across a production environment. Then the real questions start appearing: What happens when a provider goes down? How do you control which teams can access expensive models? Can you track token usage by application? How difficult is it to switch from one model provider to another?…
An enterprise AI gateway serves as a central point between applications and AI model providers. Rather than each application connecting directly to multiple providers, requests can pass through a gateway. This creates a unified control layer for tasks such as model routing, authentication, API key management, rate limiting, usage tracking, cost management, logging, observability, security policies, and fallback options.
The gateway becomes part of the AI infrastructure, so considerations around reliability, latency, security, data handling, operational complexity, and vendor dependency must be evaluated before integrating it into the production environment. Here are seven enterprise AI gateways to consider when building or operating AI applications at scale:
1. OpenRouter: Known for providing a unified interface to multiple AI models and providers, OpenRouter allows developers to use a common API layer to select models. This is particularly useful when experimentation and model choice matter. OpenRouter can simplify model integration and routing for teams who want access to many models through one interface and faster model experimentation.
However, it is important to evaluate data handling, access controls, observability, provider selection, reliability, and compliance before deploying it broadly.
2. LiteLLM: This open-source gateway can function as a self-hosted solution, providing flexibility for teams who want to maintain control over their infrastructure. LiteLLM enables consistent interface across different model providers and allows for centralized routing, fallback, logging, and access policies. It is especially useful for engineering organizations that want to avoid dependence on a hosted service.
However, running self-hosted infrastructure requires teams to consider upgrades, availability, monitoring, security, scaling, configuration, and incident response.
3. Vercel AI Gateway: Designed to simplify access to multiple AI providers within the Vercel ecosystem, Vercel AI Gateway fits naturally into modern application development workflows. It offers provider abstraction by placing a gateway layer between the application and models, allowing developers to experiment with different providers without hard-coding the architecture.
This makes it a good choice for teams already building applications in the Vercel ecosystem and wanting simplified model integration. However, it is important to evaluate governance, security, observability, provider controls, data requirements, and operational behavior separately against the organization's needs.
4. Cloudflare AI Gateway: Positioned at the intersection of network, security, and edge perspectives, Cloudflare AI Gateway provides a centralized layer for interacting with AI providers while integrating AI traffic into the broader Cloudflare ecosystem. This can be beneficial for organizations looking to leverage Cloudflare's security and performance capabilities while managing their AI infrastructure.
