AI Gateway – One secure, unified layer for every LLM
Give your engineers every model. Give your business full control. The nexos.ai gateway is the lightweight, secure layer that unifies access to 100+ LLMs, then shows you exactly who's using what, on which model, for how much.

Connect to every model through one secure layer
One integration 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 100+ 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 answer "who's burning what, on which model, for which outcome" 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 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 LLM gateway architecture from scratch and then maintaining it requires a significant development budget.
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 100+ AI models, while keeping cost control, security, and observability front and center. Here's what's built in.

Your data is always secure
No training on your data
Your data stays yours. Your data will never be used to train AI models unless you explicitly allow it. You can also enable zero data retention at the LLM level.SSO and access control
Your workspace is secured with SSO and RBAC to protect sensitive information.Hosted in Europe
The nexos.ai platform and most of our available models are hosted in Europe. You can freely decide which LLM to use based on your preferences and compliance requirements.Fully certified and secure
SOC 2 Type 2 and ISO 27001-certified. Fully compliant with the GDPR.
All your AI. One secure gateway.
FAQ
nexos.ai gateway offers more than just model connectivity. You get one secure endpoint to manage all your LLM traffic with built-in guardrails, 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.
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.
nexos.ai gateway supports models from top providers, including OpenAI, Anthropic (Claude), Google (Gemini), Meta (LLaMA), 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.
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 and guardrails 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 right AI gateway is critical – the wrong decision can create a single point of failure or bottleneck for all your AI systems. Look for a platform that offers:
- Redundancy and resilience (fallbacks, load balancing, and cloud-native reliability).
- Built-in observability (logs, traces, and usage metrics).
- Security and filtering (guardrails to reduce 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 gateway checks all these boxes and continues evolving to keep up with the AI ecosystem. We help your teams stay productive and in control.
