The proof pack
Seeded runs, a wire tap on every byte, an adversary trying to break it. Here are the numbers.
What your servers cost
One interaction is a rounding error. A year of your whole user base is the line your CFO circles in red.
Counts only the per-user compute & inference tier. Your database, storage and auth stay put. AI at flagship list rates.
For scale
The fleet
A real interaction mix, re-decided across seven device classes, from iPhone SE to no-GPU laptop.
Security you can verify
Not asserted. Intercepted. Every network call counted, under maximum pressure to escape.
Pin a workload to this device or a region. Off-scope hardware is refused as a matter of legality.
Authoritative work never runs on client silicon. Payments and compliance stay on hardware you control.
Let the device compute free, then check the answer server-side, far cheaper than recomputing it.
Your choice
Pick what matters. Every routing decision re-ranks around it. Defaults to cost.
Cheapest capable hardware, this device first.
Lowest time to first result.
Biggest capable silicon for the heavy jobs.
On battery, the frugal rungs run first.
The most reliable, already-warm rung first.
Greenest idle silicon first, no deferral.
Data stays on-device or in-region. Always.
Critical math never lands on lossy hardware.
Hostile field
Real networks drop packets, real servers fall over, and real phones overheat. Hadron keeps returning correct answers, because the user's own device is always the floor: when a server rung fails, the work quietly falls back to the device with no error thrown.
