Reduce AI costs automatically through intelligent routing, prompt caching, and context compression. Monitor usage, enforce governance, and keep every AI application running reliably.See what your data is really telling you
Connect to every model through one secure layer
One AI Gateway platform replaces every provider integration you'd otherwise build and babysit. The nexos.ai Gateway is a lightweight, secure layer that gives your teams instant access to 200+ LLMs through a single endpoint, and the moment a new model ships, it's already available to you.Optimize costs with smart routing
You don't need a frontier model for every single prompt. The nexos.ai Gateway reads each request and sends it to the best model for the job, balanced across cost, quality, and latency, automatically.See exactly what your AI costs, in real time
The nexos.ai Gateway makes every LLM call visible across every provider, then lets you control it. Cap budgets by user, team, or project before overruns happen. Logs and traces capture every prompt, response, and error, so you can see which teams, and models drive your AI costs, and act on it without guessing.One AI Gateway for every team
Built for both technical and non-technical users. One invoice, one control plane, one set of policies. The nexos.ai Gateway gives you one governed home for engineers and business teams, one bill that covers every team and project, and the same security and usage rules applied to every team, automatically.Move fast, without the scary invoice
Most Gateways force a bad trade: throttle your teams to protect the budget, or let throughput run and brace for the bill. The nexos.ai Gateway removes the trade. You get enterprise-grade rate limits so productivity never gets blocked, while smart routing and budgets keep spend predictable as you scale.Secure by default, simple by design
Security here isn't a setting you switch on later, it's the foundation the Gateway is built on. Your data stays in the EU, is never used to train models, and can run with zero data retention at the LLM level. Enterprise-grade protection your CISO signs off on quickly, without slowing the people doing the work.One AI Gateway solution for your LLM integration pain points
Whether you're launching your first model or scaling AI company-wide, nexos.ai helps you solve the biggest AI integration challenges:
High development costs
Building an
Operational overhead
Managing multiple API integrations, figuring out performance issues, and optimizing cost is a continuous challenge.
Lack of observability
Without centralized control, there's no way to see how AI is used across your organization or prevent employees from leaking sensitive data to AI systems.
Why your business needs an AI Gateway
The nexos.ai Gateway gives you direct, policy-enforced access to 200+ AI models, while keeping cost control, security, and observability front and center. Here are the main features of nexos.ai Gateway.

FAQ
An AI Gateway is ideal for businesses that need to:
- Route and manage traffic across multiple LLM providers.
- Enforce security and usage policies at the API level.
- Track and control LLM costs by user, team, or project.
- Add retrieval-augmented generation (RAG) to AI workflows.
- Orchestrate AI agents and structured tool use.
- Reduce latency and duplication through caching.
- Centralize prompt management and evaluation.
It’s a foundational layer for companies turning AI into production-ready infrastructure.
The most important functions of an AI Gateway include:
- Standardized API access to LLMs across vendors and deployment environments.
- Model orchestration, versioning, and fallback logic.
- Prompt filtering for safe inputs and outputs.
- Load balancing and failover to keep AI systems reliable.
- Cost tracking with usage visibility across teams.
- Logs and observability for every prompt, file, and response.
- A unified LLM Gateway for smarter, context-aware automation.
With nexos.ai, these features are built-in – no extra setup or engineering required.
An API Gateway routes HTTP traffic between services. An AI Gateway is purpose-built for LLMs – it handles prompt orchestration, model routing, security filtering, caching, and cost controls tailored to generative AI.
You may still use an API Gateway (e.g., for service-level routing), but when it comes to managing AI use across your stack, you need an AI Gateway.
Choosing the best AI Gateway for your business is critical – the wrong decision can create a single point of failure or bottleneck for all your AI systems.
Look for an AI Gateway platform that offers:
- Redundancy and resilience (fallbacks, load balancing, and cloud-native reliability).
- Built-in observability (logs, traces, and usage metrics).
- Security and filtering (reduces the risk of leaks and hallucinations).
- Model flexibility (no vendor lock-in and support for open/private models).
- Cost control (spend tracking and budgeting across teams).
nexos.ai checks all these boxes and continues evolving to keep up with the AI ecosystem. We help your teams stay productive and in control.
Not every company needs one – startups and very small teams running a single model on light usage can usually manage with direct provider access. An AI Gateway becomes important once AI use grows: multiple teams, multiple providers, and rising, unpredictable AI costs. For larger companies and enterprises that use AI heavily across many applications, an AI Gateway is essential. It centralizes access to every model, tracks and controls spend by team and project, enforces security and usage policies, and gives leadership full visibility into how AI is used.
Yes, and cost reduction is one of the main reasons companies adopt one. An AI Gateway lowers AI costs in several ways. Smart routing sends each request to the most cost-effective model that can handle the task, so you stop paying frontier-model prices for simple prompts. Intelligent caching reuses answers for repeat or similar queries, cutting redundant token spend. Budgets and usage controls cap spending by user, team, or project before overruns happen. And full cost tracking shows exactly where your AI budget goes, so you can optimize the biggest drivers. Together, these turn AI spend from an unpredictable bill into a managed, forecastable cost.
nexos.ai Gateway offers more than just model connectivity. You get one secure endpoint to manage all your LLM traffic with observability, fallback logic, and smart LLM routing. Our AI platform removes the overhead of integrating individual models and gives teams the tools to scale AI responsibly and reliably.
nexos.ai Gateway supports models from top providers, including OpenAI, Anthropic (Claude), Google (Gemini), Meta (LLaMA), Grok, Kimi, DeepSeek and Mistral. You can also use privately hosted or open-source models, such as LLaMA on Ollama. You’re free to mix and switch without vendor lock-in.
You connect your applications, AI agents, internal tools, and customer-facing products to that one endpoint, then route requests to any supported model without wiring up each provider separately. If you are already using the OpenAI SDK, you can point it at nexos.ai and be running in minutes, with no re-architecting. Teams that prefer a no-code path can also manage models and access through the web platform. From there, smart routing, cost controls, monitoring, and fallbacks apply automatically to every request. See the Gateway API documentation for setup details.
nexos.ai Gateway pricing depends on your business needs. For most organizations nexos.ai offer custom pricing based on your scale, usage, and requirements, so you only pay for what fits your team. Smaller teams and individual developers can view available plans on nexos.ai pricing page, while larger companies and enterprises can talk to our team for a tailored quote. Whichever route you choose, you get one bill that covers every model, team, and project, with no scattered subscriptions.
