LuxiEdge · deterministic quantitative computing
Deterministic quantitative computing, ready for real workloads.
LuxiEdge builds reproducible computing technology for quantitative and numerical work. LuxiQuant is the commercial division: pricing, Greeks, covariance, statistics, risk, and scenario work under a documented execution contract, with verifiable receipts. LuxiBook - the European option-book pricer - is the part you can download and run today. The rest is reached through a paid evaluation on agreed hardware.
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 signed receipt to the run. Every run emits a signed receipt: a SHA-256 fingerprint of the output numbers, sealed with an Ed25519 signature from the install that produced them.
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
signed 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.
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 16, 2026. Two books - the 10-row example_book.csv and a 237-row stress book - each produced a single SHA-256 output hash across five NVIDIA GPUs spanning four architecture generations, on both the CPU and the CUDA path. Twenty signed receipts are published, and every signature verifies.
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.
