If it's down

If FLUX 3 Image Klein is down

CheaperGen runs FLUX 3 Image Klein from its open weights on GPU inference for open-source models, below the official price, with automatic routing. The routing is what keeps FLUX 3 Image Klein running when capacity fails.

Automatic routing

We run FLUX 3 Image Klein across several GPU inference pools and check them every five minutes. When one slows down or fails, new requests switch to a healthy one automatically: same endpoint, same request. If nothing can take a request, it's declined up front and nothing is charged.

Failed generations are refunded

If a generation fails, the price held when you submitted goes back to your balance in full, automatically. The error says why and whether a retry can help. Error handling

A disclosed emergency price

When only pricier capacity is left, a request can run at the emergency price: never above the official price, and shown before it runs. On the API, allow_fallback_price: false keeps you at the standard price. Emergency price

FAQ

FLUX 3 Image Klein status questions

Every model's live state is on the status page.

No. FLUX 3 Image Klein is up and completing generations normally. Last checked Oct 25, 2026, 20:20 UTC; uptime over the last 30 days: 99.86%. This page updates every five minutes.

Every five minutes we check whether FLUX 3 Image Klein can be served, and we count every generation that finishes. Uptime is the share of those observations that found it working: 1 − (checks that found it unusable + generations that failed on our side) ÷ (all checks + all finished generations). Failures caused by the request itself, like a blocked prompt or an unreadable file, don't count, and degraded performance or the emergency price still count as up. A day with nothing recorded counts as fully available. Bars are green from 99%, amber from 95% and red below.

No. CheaperGen is independent of Black Forest Labs, and this page doesn't monitor Black Forest Labs' own console or API. It shows FLUX 3 Image Klein as served by CheaperGen from its open weights on GPU inference for open-source models, across several routes, measured by our own health checks and the generations that run here: whether FLUX 3 Image Klein works on CheaperGen right now.

It's refunded automatically: the price held when you submitted goes back to your balance in full, and the generation's error says why and whether retrying can help. When one inference pool fails, new requests switch to a healthy one automatically. If nothing can take a request, it's declined before anything is charged.
