FAQ
Gateway charges a small margin on top of underlying provider costs. One consolidated invoice instead of managing billing across multiple providers. No platform fees, no per-seat charges.
All major providers, including OpenAI, Anthropic, Google (Gemini), Grok (X), Mistral, and Cohere. New providers and models are added regularly and available through the same API.
Gateway provides deterministic and intelligent routing to optimize for cost, performance, latency, or the best model for each task. When a provider degrades, traffic automatically shifts to maintain reliability.
Most teams make their first call in minutes. If you're already calling LLM APIs, it's a single endpoint swap. Routing, cost controls, and security can be configured from the dashboard after you're connected.
Yes. Set Gateway as your base URL. Existing code works as-is, no new SDK required. A native SDK is available for deeper integration.
