Built-in presetsStart on anyrouter/free or anyrouter/auto
Two built-in virtual models: Go+ free failover (anyrouter/free) and stable paid failover (anyrouter/auto). Do not pick a flaky SKU for your first request.
01
The problem
What this is for
A first request that pins a single free SKU often 404s or 429s. You want something that is answering right now, with automatic fallback.
02
What to do
Three steps, then copy
- 1.Create a key. anyrouter/free needs the Go plan ($2/mo) or a donated provider key; it does not deduct credits and is capped at 1,000 requests/day.
- 2.Call model anyrouter/free for the subsidized free chain, or anyrouter/auto for paid models that are healthy right now.
- 3.Read the model pages and the free-tier docs for daily caps and failover behavior.
