The gateway to
every AI model.
One endpoint. Every frontier model. Built for teams that ship at the speed of inference.
One API.
Every model.
Change one line of code. Access GPT-4o, Claude Opus, Gemini, Llama, Mistral, DeepSeek, Flux — and 90+ more. Your existing OpenAI SDK code works unchanged.
- OpenAI SDK drop-in compatible
- Stream, function calling, vision — all supported
- Automatic fallback routing
- Sub-100ms routing overhead

Fallback chain
Better prices.
Better uptime.
Every call gets routed to the cheapest, fastest, healthiest provider — automatically. One dashboard. No vendor lock-in. No 3am pager duty.
Best price routing
Automatically routes each request to the cheapest healthy provider. Up to 40% cheaper than direct.
Automatic fallback
If a provider goes down, requests instantly reroute. Your app never sees a 500.
Unified billing
One invoice, one dashboard. No juggling 10 API keys across 10 vendors.
Zero lock-in
Swap models with one string change. Standard OpenAI schema across every provider.
We’ve spent the last year wiring AI into production for our own apps and watched the same bill arrive from five different vendors. Synal is the gateway we wished existed: one key, one invoice, the cheapest healthy lane chosen for us, every modality under one roof.
We’re building it in the open — shipping to a small private beta first, then opening up early 2026. If you’ve ever juggled three SDKs to ship one feature, this is for you. Tell us what you need; we’ll prioritize accordingly.
Every modality.
One account.
The frontier of conversation.
Stream chat, function calling, vision and reasoning across every leading text model. Switch providers with one string change.
