Stop overpaying for LLMs.
Route every call to the cheapest model that can do the job.
ModelSwitch is a drop-in proxy that picks the cheapest capable model per request, auto-fails-over when a provider goes down, and shows per-feature cost — with a hard monthly budget cap that blocks overspend before it happens. The CFO-friendly guardrail your model bill is missing.

Built to cut the bill, not just proxy the call
Three things every team scaling LLM features eventually needs — in one layer.
Cost-aware routing
Declare the capability tier a task needs; ModelSwitch sends it to the cheapest model that clears that bar across every provider you've connected. Pin a model when you must.
Automatic failover
When a provider 5xxs or rate-limits, the request slides to the next-cheapest capable model in milliseconds. No outage page, no dropped calls.
Hard budget caps
Set a monthly ceiling. When the next call would breach it, ModelSwitch returns a clean 402 instead of a surprise invoice. Per-feature cost so you know what is spending.
How much are you overpaying?
Most teams default everything to a frontier model. Routing routine calls to a capable cheaper one is where the savings hide.
