Fast. Reliable. Affordable. Yes, all three.Stop compromising on performance to manage your AI infrastructure costs.

Proxium sits between your apps and every AI provider behind one base URL. It routes, caches, and fails over automatically — so you get all three, starting today.

No implementation. No code changes.

Three problems, one checkpoint

Every one of these used to mean a separate integration, a separate vendor contract, or a 2am page. Now they're just on by default.

Routing

Out-of-the-box routing and classification

Send auto as the model, and a classifier picks the right one for each request — a cheap model for a simple ask, a frontier model when it actually matters. Choose a ready-made routing for your vendors in one click, or set your own.

"model": "auto"

Cost

Cut the cost. Cheap AI, by default

Caching answers a repeated question without a round trip to the provider. A spending ceiling you set for each app keeps runaway spend from ever reaching your bill.

Uptime

AI that's always on

When a provider rate-limits, slows down, or goes dark, Proxium fails over to another one. Your app keeps calling the same endpoint — it never has to know, and it never goes down because one vendor did. No infrastructure to maintain, just one endpoint that stays up.

model A→503
another vendor→200
your app→one answer

Your agents remember

Proxium keeps what your project's conversations taught it, and your agents read it back before they start. Connect any MCP client to the Proxium MCP server, and every agent on the team starts from what the others already learned.

agent A→learns "deploys need the staging check"
→memory
agent B→reads it before it starts

Start right away.

Point your existing SDK at one URL. Everything else — routing, caching, failover — is already on.
