LuxiEdge · deterministic quantitative computing
Deterministic quantitative computing, ready for real workloads.
LuxiEdge builds reproducible computing technology for quantitative and numerical work. Through LuxiQuant, customers can run pricing, Greeks, covariance, statistics, risk, and scenario workloads with documented execution behavior and verifiable receipts. LuxiBook is our most complete product today, and paid workload evaluations are open.
Flagship product
LuxiBook prices a European option book and returns a receipt.
LuxiBook is a closed-binary European option-book pricer. It reads a CSV book, prices with Black-Scholes / Black-76, returns five Greeks per position, and attaches a SHA-256 receipt to the run.
What it does
You bring time to expiry, rate, and volatility. There is no live market feed, no implied-volatility solver, and no VaR. The binary runs on your machine. You can check the receipt yourself.
Built for quantitative, trading, risk, and financial-infrastructure teams that need a defined book priced the same way, with proof attached.
Try it, then evaluate a real book
Downloads for macOS Apple Silicon, Linux x86_64 CPU, and Linux CUDA are
on the demo page, with example_book.csv and checksums.
Paid evaluations measure LuxiBook, or a related LuxiQuant workload, against your comparator on agreed hardware.
LuxiQuant
What LuxiQuant does
LuxiQuant is LuxiEdge's commercial quantitative-computing division. It is numerical work: pricing, risk, statistics, and deterministic kernels. It is not LLM weight quantization, and it is not an inference serving stack.
Pricing and Greeks
Closed-form European pricing and five Greeks, as in LuxiBook, with a receipt on the run.
Risk and scenario analysis
Reproducible scenario batches and risk calculations under a documented execution contract.
Covariance and statistics
Streaming statistics and online covariance for quantitative pipelines that must replay cleanly.
Deterministic numerical processing
Numerical expressions and kernels with defined execution order and canonical inputs and outputs.
Reproducible calculations across supported hardware
CPU, tested NVIDIA GPU, and ARM paths where the current site documents support. Contracts are configuration-specific.
Receipts
SHA-256 receipts over output bytes, so a later re-run can be checked against what was stored.
Commercial value
The value is reproducibility, auditability, correctness, hardware flexibility, performance and energy measurement, and easier comparison against a named system.
Determinism and receipts, in plain English
Same defined workload, same verified result. A receipt is a hash of what the computation produced under a documented configuration. Store it when you run. Match it when you re-run.
Output determinism
The claim is about the result: the same inputs, under the same documented mode, produce the same verified output. That is not the same as a runtime that happens to be fast or stable from run to run.
What a receipt is not
A file checksum tells you the download was not corrupted. A receipt tells you what a specific computation produced. They are not interchangeable. Performance stability is also a different claim.
example_book.csv on specific boxes
(August 15, 2026). It is not a universal cross-platform bit-exact claim.
Evidence, summarized
Claims are labeled by source, workload, hardware, date, and validation status. The Evidence page is the register. This is the short version.
LuxiBook receipt check
Internal, August 15, 2026. The published example_book.csv
produced the same SHA-256 receipt on Mac Mini CPU, RunPod x86 CPU, A100,
H100, and H200.
Independent numerical-engine evaluation
TestFort QA Lab, December 2025, evaluated a seven-function numerical suite. That evaluation is not LuxiBook.
Inference measurements, including the independent TestFort packed-prefill report, live on Evidence and Research. They are not homepage proof of LuxiQuant.
Paid evaluation
Evaluate LuxiEdge on your workload.
A paid, fixed-scope evaluation. You bring a workload and a comparator. We agree the hardware. We measure correctness, determinism, speed, energy, and receipts, and we deliver a documented head-to-head. The next step, if the numbers warrant it, is a production conversation.
The process
- Customer workload and named comparator
- Agreed hardware and measurement contract
- Correctness, determinism, speed, energy, receipts
- Documented head-to-head report
- A clear next production step, or a clear stop
The path
Fixed-scope benchmark, then a design-partner pilot, then enterprise or OEM licensing if the fit is real.
Public evidence stays free. Custom work is paid. We do not take on open-ended unpaid consulting.
LuxiRisk
LuxiRisk is a free LuxiQuant project that demonstrates accessible, reproducible risk analysis. It is a position-sizing CLI with Ed25519 receipts, not the primary product, and not a retail crypto company.
Research
Luxi Inference is LuxiEdge's research program for deterministic, energy-aware transformer execution. Prefill, decode, receipts, and energy measurement are documented on the Research and Evidence pages, each with its source and scope.
