SynapseX — powered by SoftQuantus

The AI scientist
with its own laboratory.

Domain-trained models, wired into a quantum-classical lab they can actually operate. Describe an anomaly. SynapseX builds a differential diagnosis, probes it on free simulators, and escalates to real QPUs, GPUs and VMs only when the evidence justifies the spend — with your approval on every credit.

Simulators liveEvidence signedQPU early access

Frontier labs rent you intelligence. Clouds rent you compute. SynapseX ships both — closed into one loop, metered by one ledger, ending in one chain of evidence.

How it works

Debugging possibilities,
the way agents debug code.

Coding agents won by owning a loop — reproduce, isolate, fix, confirm. SynapseX runs the same loop on science, where the instruments are simulators, QPUs and GPUs instead of a compiler.

"This material should be stable and isn't." "Hardware disagrees with my simulator." No job specs required.

BRAIN

SynapseX Models

SynapseX-Q1 family (working name)

Trained on the instruments, not just the literature. They plan probe sequences, call QCOS natively, read calibration snapshots, and reason about cost as a first-class variable.

Platform API

Every credit accounted for: atomic reserve → settle, idempotent debits, an append-only ledger, per-tenant entitlements. 1 credit = $0.01. Even our paywall is honest — it's an HTTP 402.

Powered by QuantumOS

One quantum OS
under every surface.

QCOS is SoftQuantus's QuantumOS — the quantum-classical orchestration engine. Chat, the CLI and the API all reach the same lab through it: free simulators today, partner QPUs in early access, GPUs and HPC next. A run you start on any surface lands on the same backends, the same metered ledger, the same signed evidence.

Evidence

Reproducibility isn't a feature.
It's the output format.

Each execution produces a signed evidence record: what ran, where, under which calibration, with which seed, at what cost, returning which distribution. Verify the signature, re-run the probe, or attach the record to a paper or an audit.

If a result can't carry its evidence, SynapseX doesn't call it a result.

Why we train our own models

The moat isn't today's model.
It's the data only a closed loop produces.

Because we own the meter, the engine and the muscle, every session yields a trajectory nobody else has: problem → diagnosis → probe sequence → real cost → signed outcome.

General models read papers about experiments. Ours learn from the experiments themselves — including the failed probes that never get published. Every run makes the next diagnosis cheaper.

This trace only exists because one company owns the models, the meter, the engine and the muscle at once. It can't be bought — only produced.

The diagnosis AND the instruments
Metered per credit, open to a single researcher, evidence-signed from the first free probe.
The muscle

One balance.
Every backend.

QCOS turns every backend into an instrument the agent can call — from free simulators to real quantum hardware. One credit balance spans all of it, and the cheapest capable probe always runs first. We list hardware only when it's real.

Pricing

Start at zero.
Scale by evidence.

Simulation is free. You pay only when a job touches paid hardware — estimated first, reserved before it spends, settled for what it used.
