Why AxForge

Why run Xev on AxForge

Jev-compatibleXev speaks the System One format — the same request, question types and answer shape. Switch by changing the endpoint and the key.
Probabilities, not proseEvery answer is a typed value with the probability behind it, so your code branches on it directly and holds back when it isn't sure.
Hosted in SwedenServed from hardware AxForge owns in Stockholm, with zero prompt retention — nothing stored, nothing trained on.
