Product ยท deterministic numerical runtime
LuxiQuant: numerical computing with defined behavior and receipts.
LuxiQuant is a deterministic numerical and quantitative runtime for workloads where the same input must produce the same output, every time, with proof attached. It is a numerical execution engine - not an LLM weight-quantization tool, and not an inference serving stack.
What it is
A compact, locally executed numerical runtime with documented execution modes. You choose the contract; the engine behaves as documented for that contract.
Binary and API surfaces
Ships as a single compact binary with a REST interface. JSON expressions in, results plus a SHA-256 receipt out. Runs locally with no cloud dependency after deployment.
Defined execution behavior
Each execution mode carries a documented contract: the f64 CPU gold path provides the strongest reproducibility contract; fast f32 and GPU paths carry configuration-specific contracts that are never presented as equivalents.
Reproducible numerical work
Defined execution order and canonical requests and outputs, so supported workloads can be re-run and compared byte-for-byte under the documented conditions.
Cryptographic receipts
Every response can carry a SHA-256 receipt over the output bytes. Store it at computation time; a matching receipt on re-run confirms byte-identical output under the same documented configuration.
Quant and risk workloads
Receipt-enabled risk, Greeks, streaming statistics, online covariance, and scenario-batch processing for reproducible quantitative pipelines.
Supported platforms
CPU scalar, AVX2, AVX-512, and ARM Neon paths; CUDA on tested NVIDIA GPUs. Vulkan is available but experimental. Per-platform status: Capabilities.
Independently evaluated - TestFort, December 2025
TestFort QA Lab independently evaluated a defined deterministic numeric workload on NVIDIA H100 hardware. The evaluation did not certify every function, platform, backend, or expression.

What a paid pilot looks like
A design-partner pilot measures LuxiQuant against your reference workload, on agreed hardware, under an agreed measurement protocol.
- Define the workload, reference method, and acceptance criteria together.
- Run matched comparisons with receipt-attested outputs.
- Deliver a scoped measurement report: correctness, throughput, and measured energy for the agreed configuration.
