LuxiEdge

Deterministic vector math. JSON in, results out, SHA256 hash on every response.

Same input gives identical output across CPU, GPU, ARM, x86. Bit-for-bit. No floating point drift between platforms.

Download

Go to Releases and download the binary for your platform.

Platform	Binary	Size
macOS ARM64 (M1/M2/M3)	luxiedge-macos-arm64	2.1 MB
Linux x86_64 GPU	luxiedge-linux-x86_64-gpu	2.5 MB
Linux x86_64 CPU	luxiedge-linux-x86_64	2.5 MB
Linux ARM64	luxiedge-linux-arm64	1.0 MB

Each binary has a corresponding .sha256 checksum file. Verify your download: shasum -a 256 luxiedge-macos-arm64

Compare the output to the contents of luxiedge-macos-arm64.sha256.

Quick Start

Step 1: Download and Prepare

Download the binary for your platform from the Releases page. Then make it executable: chmod +x luxiedge-macos-arm64

Step 2: Start the Server

./luxiedge-macos-arm64 --port 9090

You should see: Listening on http://0.0.0.0:9090...

The server is now running and ready to accept requests.

Step 3: Send Your First Request

Open a new terminal window and run: curl -X POST http://localhost:9090/evaluate
-H "Content-Type: application/json"
-d '{"expr":"sin(x)","values":[0.5,1.0,1.57,2.0,3.14],"precision":"f32"}'

You will receive: { "expr": "sin(x)", "results": [0.47942554, 0.84147096, 0.99999964, 0.9092974, 0.0015926529], "count": 5, "precision": "f32", "sha256": "9d7aa9e5e6b09ae8bb377f8c8ea01fbfa9e98a53814f533bee0681d924703ff1" }

That SHA256 hash is identical on every platform: macOS, Linux, CPU, GPU, ARM, x86. That is the point.

Gold Master Hashes

These hashes verify your binary is working correctly. All hashes below were generated using input values [0.5, 1.0, 1.57, 2.0, 3.14] with f32 precision.

If your binary produces these exact hashes, it is operating correctly and deterministically.
