FastRouter.ai is a unified API gateway that connects multiple leading LLMs and multimodal models through a single endpoint, so developers don’t need separate integrations for each provider.
One gateway for many LLMs
FastRouter.ai lets you call models from different vendors without changing client code. It supports both text and multimodal models, and newly released models become available once FastRouter adds them.
- Single endpoint for multiple providers
- Access to models such as Gemini 3 Pro, GPT-5.1, Grok, and Claude 4.5 Opus
- Faster experimentation without rebuilding integrations
Intelligent routing and cost controls
Auto-routing selects an appropriate model for each task—from cheaper, faster options to higher-accuracy models—helping balance quality and cost. Built-in analytics track usage by project, team, or cost center, with real-time limits.
- Task-based model selection
- Usage analytics by org structure
- Real-time budget and limit management
Built for high throughput
FastRouter.ai is designed for heavy production traffic and claims operation without strict QPS limits, including workloads reaching millions of requests per second.
- Infrastructure for high-load applications
- Routing and load balancing handled by FastRouter.ai
