[A comparison of the top 10 AI gateways for platform engineering teams, focusing on performance, reliability, and enterprise features. This guide reviews tools like Bifrost, LiteLLM, and others to help teams choose the right solution for managing production AI workloads.]

An AI gateway is a centralized entry point that routes, secures, and observes traffic to large language models (LLMs) from multiple providers. For platform engineering teams, deploying a gateway is a critical step in managing the complexity, cost, and risk of production AI applications. A gateway standardizes access, enforces governance, and provides resilience against provider outages, making it an essential piece of modern AI infrastructure.

This article reviews the 10 best AI gateways available today, evaluated from the perspective of a platform engineering team responsible for scalability, reliability, and security. The analysis covers open-source and managed solutions, with a focus on features that support enterprise requirements.

Key Criteria for Evaluating AI Gateways

Platform teams should assess AI gateways on several core dimensions:

Performance: The gateway's latency overhead and throughput under load. High-performance gateways add minimal latency (measured in microseconds) to each request.
Reliability: Features like automatic provider failover, load balancing, and retries are essential for maintaining application uptime.
Unified API: A single, consistent API endpoint for accessing a wide range of models from providers like OpenAI, Anthropic, Google, and AWS. An OpenAI-compatible API is the industry standard.
Governance and Security: The ability to enforce access controls, budgets, and rate limits using virtual keys, and apply security policies like guardrails.

It offers significant flexibility but requires expertise in configuring multiple Azure services to build a complete gateway solution.

Best for: Enterprises committed to the Microsoft Azure stack that need to integrate AI workloads with existing Azure governance, security, and operational policies.

9. Google Vertex AI

Similar to Azure and AWS, Google Cloud's Vertex AI platform offers a suite of tools that can be used to build a gateway for AI models. Vertex AI provides access to Google's Gemini models, as well as models from third parties, through a unified API.

Platform teams can use Vertex AI Endpoints and integrate them with services like Apigee API Management to handle routing, authentication, and rate limiting. The platform excels at MLOps, offering tools for model evaluation, monitoring, and management. This approach provides a powerful, scalable solution for teams building within the Google Cloud ecosystem.

Best for: Organizations building on Google Cloud who need a comprehensive MLOps platform for managing the entire lifecycle of both proprietary and open-source models.

10. Ollama

Ollama is a tool for running open-source LLMs locally. While it is primarily a local inference server, it exposes an OpenAI-compatible API. By deploying Ollama on a centralized server, a platform team can create a private, self-hosted gateway for a suite of open-source models.

This setup is ideal for development, testing, or production use cases that require data privacy and full control over the model environment. It is lightweight and easy to manage. However, to achieve enterprise-grade reliability and governance, it should be placed behind a more capable AI gateway that can provide features like failover, load balancing, and virtual keys.

Best for: Teams that need a simple, efficient way to self-host and serve a variety of open-source models with full data privacy and control.

How to Choose the Right AI Gateway

The best AI gateway for a platform engineering team depends on the organization's specific needs. For teams that require top-tier performance, robust governance, and the flexibility to deploy anywhere, an open-source solution like Bifrost is a leading contender. For those deeply embedded in a specific cloud ecosystem, the native offerings from AWS, Azure, or Google provide seamless integration. Simpler, developer-focused tools like LiteLLM are excellent for getting started quickly.

Ultimately, the goal is to select a gateway that abstracts away the complexity of a multi-provider AI world, enabling developers to build applications quickly while the platform team ensures reliability, security, and cost control. Teams can evaluate the options by starting with the open-source versions or exploring managed trials, and a good next step is to request a Bifrost demo or review its open-source repository.

8 Signs Your Company Has a Shadow AI Problem

Babatunde Fashola — Thu, 09 Jul 2026 10:02:20 +0000

Ungoverned AI usage presents significant risks to enterprise data security and compliance. This article identifies the common indicators of shadow AI, detailing how an AI gateway combined with endpoint governance can mitigate these challenges.

The rapid adoption of artificial intelligence tools by employees in the workplace often outpaces an organization's ability to govern their use. This creates "shadow AI," where individuals and teams use AI applications and models without IT oversight, security vetting, or adherence to corporate policies. These ungoverned AI interactions can expose sensitive data, create compliance vulnerabilities, and incur unmanaged costs. Recognizing the indicators of shadow AI is the first step toward effective mitigation and control.

What is Shadow AI?

Shadow AI refers to the use of AI tools, services, or models within an organization without the knowledge or explicit approval of IT, security, or compliance teams. This can include employees leveraging public LLMs like ChatGPT or Claude, integrating unapproved AI-powered coding assistants into their development workflows, or even deploying local AI models on company devices. The core characteristic is the absence of central governance, making it difficult for organizations to track, audit, or secure these interactions.

The proliferation of accessible AI tools, coupled with a demand for increased productivity, fuels shadow AI. Employees, seeking efficient solutions to daily tasks, often bypass formal procurement and approval processes, leading to an invisible landscape of AI usage that operates outside of established security perimeters.

The Risks of Ungoverned AI Usage

The uncontrolled use of AI tools poses several critical risks for enterprises:

Data Leakage and Exposure: Employees may inadvertently input proprietary information, confidential data, or personally identifiable information (PII) into public AI models, leading to potential data breaches and intellectual property theft. The terms of service for many public AI services often grant the provider rights to use submitted data for model training, creating an unacceptable risk for sensitive enterprise information.
Compliance Violations: Without oversight, AI usage can violate regulatory requirements such as GDPR, HIPAA, SOC 2, or ISO 27001. Organizations may fail to meet data residency, privacy, and auditing mandates, incurring hefty fines and reputational damage.
Security Vulnerabilities: Ungoverned AI tools may introduce malware, phishing risks, or unpatched vulnerabilities into the corporate network. AI-generated code, for example, could contain exploitable flaws.
Cost Overruns: While individual AI tool usage may seem minor, aggregated use across an organization can lead to significant unbudgeted expenses, particularly with API-based services.
Lack of Auditability and Visibility: When AI operations occur outside approved channels, there is no audit trail of who used which model, what data was processed, or what decisions were made, rendering incident response and forensic analysis nearly impossible.
Bias and Hallucination: Using unvetted AI models can introduce biased outputs or factual inaccuracies ("hallucinations") into business processes, potentially impacting decision-making or customer interactions.

8 Signs Your Company Has a Shadow AI Problem

Identifying shadow AI requires vigilance and a keen understanding of the signals that suggest ungoverned usage.

1. Unexplained Spikes in Cloud API Costs

Unexpected increases in bills from public cloud providers (e.g., AWS, Azure, GCP) or specific AI model providers (e.g., OpenAI, Anthropic) without corresponding, centrally approved projects can indicate rogue AI API calls. These spikes often occur when individuals or small teams experiment with AI services, unknowingly consuming significant resources.

2. Employee Mentions of Unapproved AI Tools

Casual conversations among employees about using specific AI apps or services—especially if these tools are not part of the approved software catalog—are a direct indicator of shadow AI. Such discussions often arise when teams find workarounds to perceived inefficiencies.

3. Presence of AI-Related Software on Endpoints

Discovery of desktop AI applications or browser extensions on employee machines during routine audits or security scans can point to ungoverned usage. These applications might range from coding assistants to advanced data analysis tools, all operating outside of central control. An endpoint agent like Bifrost Edge helps administrators inventory installed AI applications across a fleet, transforming this blind spot into actionable data.

4. Lack of Centralized AI Governance Policies

If an organization lacks clear, enforced policies regarding AI tool usage, data handling with AI, or acceptable AI models, it creates a vacuum that employees will inevitably fill with their own choices. The absence of a defined AI governance framework is a precursor to shadow AI.

5. Suspicious Outbound Network Traffic Patterns

Unusual traffic volumes or connections to unknown AI service endpoints from corporate networks can be a sign. Deep packet inspection or network monitoring tools might reveal frequent connections to generative AI APIs that are not tied to any sanctioned application.

6. Discovery of Unapproved MCP Servers

The Model Context Protocol (MCP) enables AI agents to connect to external tools for enhanced capabilities. If security teams find unapproved MCP servers configured within employee-used AI tools (such as coding agents or desktop LLMs), it signals that users are extending AI functionality without oversight. Bifrost Edge can inventory MCP servers configured within AI applications across an organization’s devices, providing crucial visibility into this often-hidden activity.

7. Data Storage in Unsanctioned AI Cloud Services

Evidence of sensitive company data appearing in cloud storage associated with unsanctioned AI tools or services is a critical red flag. This often comes to light during data loss prevention (DLP) scans or through security vendor alerts indicating data egress to unknown destinations.

8. Audit Logs Showing Missing AI Context

For applications that do use approved AI services, inconsistent or incomplete audit logs that lack context about the models used, data processed, or user responsible can indicate that some AI interactions are bypassing the central logging mechanism. This often happens when developers use direct API calls that skip integrated logging frameworks.

How to Address Shadow AI with an AI Gateway and Endpoint Governance

Addressing shadow AI requires a multi-pronged approach combining policy, education, and technical controls. A key technical solution involves deploying an AI gateway complemented by endpoint AI governance.

The Bifrost AI gateway, an open-source AI gateway by Maxim AI, provides a central control plane for all AI traffic. It allows organizations to:

Enforce virtual keys, budgets, and rate limits across all models and providers.
Implement guardrails for content safety and sensitive data detection before prompts reach models.
Route traffic intelligently to manage costs, ensure reliability with failover, and optimize performance.
Generate comprehensive audit logs for compliance purposes.

To extend this governance to every employee machine and eliminate shadow AI, Bifrost uses Bifrost Edge. As an endpoint agent, Bifrost Edge ensures that the same policies defined in the Bifrost gateway are enforced on every device. It brings all AI traffic from desktop applications, browser AI, coding agents, and MCP servers under central control, without requiring users to reconfigure their applications.

Key capabilities of the "AI Gateway + Bifrost Edge" approach include:

Endpoint App Governance: Administrators can allow or deny specific AI applications (e.g., Claude Desktop, ChatGPT web, Cursor) across the fleet, with Edge transparently blocking unauthorized tools.
MCP Server Control: Edge automatically discovers and inventories MCP servers configured in employee AI tools, allowing security teams to approve or deny them centrally.
Unified Guardrails: All gateway-level guardrails, including secrets detection and custom regex for PII, are applied directly to endpoint AI traffic, protecting data before it leaves the device.
MDM Deployment: Bifrost Edge can be deployed silently and managed fleet-wide via MDM platforms like Jamf, Microsoft Intune, or Kandji, ensuring seamless rollout and minimal user friction.

Proactive Steps for AI Governance

Combating shadow AI effectively involves more than just detection. Organizations should also:

Develop Clear Policies: Establish and communicate clear guidelines for AI usage, data handling, and acceptable tools.
Educate Employees: Train staff on the risks of shadow AI and the importance of using approved channels.
Provide Approved Tools: Offer vetted, secure AI tools and services that meet employee needs, reducing the incentive to seek unsanctioned alternatives.
Implement Technical Controls: Deploy an AI gateway with endpoint governance (like Bifrost + Bifrost Edge) to gain comprehensive visibility and enforcement.

By recognizing the signs and implementing robust governance, organizations can transform shadow AI from a hidden liability into a centrally managed, secure, and compliant asset. Teams evaluating AI gateways and endpoint governance solutions can request a Bifrost demo to see these capabilities in action.

Observability for LLM Applications: Metrics That Matter

Babatunde Fashola — Thu, 02 Jul 2026 17:25:32 +0000

Large Language Models (LLMs) are no longer experimental toys; they are core components of production applications. But as developers move from prototypes to real-world deployment, they face a new set of challenges. Unlike traditional software, where a bug is a bug, an LLM's "failure" can be subtle, subjective, and buried in a chain of non-deterministic outputs. This is where LLM observability comes in. It's the practice of gaining deep, real-time insight into how your LLM-powered systems are behaving, performing, and, most importantly, delivering value.

Traditional Application Performance Monitoring (APM) tools are essential but insufficient for this new paradigm. An API can return a 200 OK status while the LLM hallucinates incorrect information, creating a silent failure that impacts user trust. Effective LLM monitoring goes beyond infrastructure health to analyze the quality and content of the model's outputs.

This post breaks down the essential metrics you need to track to ensure your LLM applications are reliable, accurate, and cost-effective.

Performance Metrics: Speed and Scale

Performance is the bedrock of user experience. For interactive applications, slow responses can be just as frustrating as wrong answers. Key performance metrics provide insight into the efficiency and scalability of your system.

Latency: This measures the time it takes to get a response from the model. It's often broken down into two parts:
- Time to First Token (TTFT): How quickly the user starts seeing a response. This is crucial for maintaining engagement in streaming applications.
- Total Response Time: The time taken to generate the complete response. Long response times can degrade the user experience in real-time applications.
Throughput: This metric quantifies the system's processing capacity, often measured in requests per second or tokens per second. While latency focuses on a single request's speed, throughput measures the system's ability to handle concurrent loads, which is vital for scaling multi-user applications.

You can monitor these with standard APM tools, but they gain context when correlated with other LLM-specific metrics. A spike in latency might be caused by longer prompts, a more complex model, or issues with a third-party provider.

Quality and Accuracy Metrics: The Core Challenge

This is where LLM observability diverges most from traditional monitoring. Quality is not a simple pass/fail test; it's a multi-faceted assessment of the LLM's output.

Relevance and Correctness: Does the model's output actually address the user's prompt, and is it factually accurate? For RAG (Retrieval-Augmented Generation) systems, this extends to checking if the response is grounded in the provided context.
Hallucination Rate: This measures how often the model generates information that is nonsensical or factually incorrect. Minimizing hallucinations is one of the most critical challenges in building trustworthy AI systems. Production teams often aim for a hallucination rate below 0.5%.
Semantic Similarity: For tasks like summarization or question-answering, you can measure the semantic distance between the LLM's output and a "golden" reference answer using vector embeddings. This helps quantify correctness even when the wording isn't identical.
Toxicity and Bias: It is crucial to monitor for harmful, offensive, or biased language to ensure the application behaves responsibly. This often involves using another model or a predefined list of terms to classify the output's safety.
Tool Use Accuracy: For AI agents that use external tools, you need to track whether they are calling the correct tool with the right parameters to accomplish a given task.

Traditional metrics like BLEU and ROUGE, designed for machine translation and summarization, are often too rigid for the semantic nuances of modern LLMs and can penalize valid, creative responses. Many teams now employ "LLM-as-a-judge," where another powerful LLM is used to evaluate the primary model's output against a set of criteria.

Cost Metrics: Taming the Token Economy

LLM costs are variable and can be unpredictable. Unlike fixed-price APIs, costs are driven by token consumption, which can fluctuate wildly based on prompt length, conversation history, and model choice.

Token Usage: The fundamental unit of cost is the token. You need to track both input tokens (from the prompt) and output tokens (from the completion) for every single call.
Cost Per Request/Trace: By combining token counts with the provider's pricing, you can calculate the exact cost of each interaction. This is essential for understanding the financial impact of different features or user behaviors.
Cost Attribution: A mature observability setup allows you to attribute costs to specific users, features, or tenants. This helps identify which parts of your application are driving the most spend and where optimization efforts should be focused.

Effective cost monitoring requires capturing data at the level of individual API calls and aggregating it up to the level of a full trace or user session. This detailed view can reveal optimization opportunities, such as identifying unnecessarily long prompts or routing simpler queries to cheaper, faster models.

Operational Health: Tracing and Logging

To monitor all these metrics effectively, you need a solid foundation of logging and tracing.

Distributed Tracing: This is the backbone of LLM observability. It allows you to follow a single request as it flows through your entire system—from your application frontend, through various microservices, to the LLM provider, and back. A trace connects all the individual operations (spans) of a request, making it possible to debug complex, multi-step agent workflows.
Comprehensive Logging: Log everything. Every prompt and response pair, model name, version, timestamp, latency, and token count should be captured. This detailed record is invaluable for debugging, auditing, and fine-tuning your model over time.

Putting It All Together

LLM observability is not a single tool but a foundational practice for building reliable, production-grade AI applications. It’s about moving from "it seems to work" to a data-driven understanding of performance, quality, and cost. By tracking the right metrics from day one, you can catch issues before your users do, optimize for both user experience and financial efficiency, and ship innovative AI products with confidence.
