FFluxen
Not another AI gateway

Your AI traffic isn't short on gateways. It's short on decisions.

Fluxen proxies OpenAI, Gemini, and Ollama traffic too — but that's the substrate, not the product. The product is finding what's inefficient, proving the fix against your real history, applying it safely, and confirming it actually worked.

The core loop

1. Understand

Every request through the gateway is accounted for — cost, tokens, model, provider, latency, cache status. No sampling, no estimation.

2. Identify

Four detectors continuously look for real, evidence-backed inefficiency: model cost, repeated requests, token drift, and traffic anomalies.

3. Simulate

Before anything changes, Fluxen replays the scenario against your real historical traffic and shows the actual cost delta — not a guess.

4. Control

Apply a proven change with one human-confirmed action: percentage-based model routing, exact caching, budgets, rate limits, or model restrictions.

5. Measure

Every applied change gets a before/after verdict against real traffic 7 and 14 days later — successful, partial, no effect, or regressed, with one-click revert.

What makes this different

Evidence before action

Every opportunity shows its evidence — sample size, eligible traffic, confidence — before you're asked to do anything.

Simulation before production

Nothing changes production traffic until you've seen the real, replayed impact against your own history.

Measured, not assumed

Fluxen tells you what actually happened after a change, not just what it estimated beforehand.

Three providers, one gateway

OpenAI, Google Gemini, and Ollama — behind one OpenAI-compatible endpoint. Point your existing client at Fluxen and route, cache, and control traffic across all three without touching application code.
