Trestle sits between your app and the AI providers — intelligently routing each request to the right model at the right cost, with automatic failover and real-time spend visibility.
// Before Trestle — always using the expensive model
const res = await openai.chat({ model: "gpt-5.4" });
// After — one line change, Trestle handles the rest
const res = await trestle.chat({
family: "openai",
routing: "smart" // routes by complexity automatically
});
// → Used gpt-5-mini · saved $0.041 · 340msYour app sends a request to Trestle exactly like you'd send it to OpenAI. One line change — same SDK, same format.
Trestle analyses the request and scores complexity 1–10 in milliseconds. Simple questions stay small. Hard problems get serious models.
Request forwarded to the optimal model. Cost, latency, and routing decision logged in real time. You see everything.
See every request, its cost, which model handled it and why — as it happens. Not tomorrow. Not in 24 hours. Now.
Provider goes down? Trestle detects it in seconds and reroutes to your fallback. Your app keeps working. Your users never notice.
Need a specific model for compliance or consistency? Pin it. Trestle will never silently upgrade you or change behaviour without your say-so.
Set a monthly cap. Auto top-up fires when credits hit $10 — just like OpenAI but with full visibility on where every dollar went.
Trestle speaks OpenAI's API format. Change one URL, one key. No SDK changes, no rewrites, no migration headache.
Simple credit-based pricing. No subscriptions, no surprises.
