SafetensorsExporter class

Utility class for serializing and exporting GPUTensor weights into the Hugging Face Safetensors binary format. Handles flattening nested lists, pulling buffers from VRAM to CPU, converting values to 32-bit floats, and writing the 8-byte length prefix, JSON metadata header, and raw data buffer.

Static Methods

saveModel(Map<String, GPUTensor> modelTensors, String outputPath) → void

Exports a map of GPUTensor instances to disk at outputPath adhering to the Hugging Face Safetensors format. Pulls tensor data from VRAM to CPU, flattens dimensions, packs the data into little-endian Float32 byte buffers, constructs the JSON metadata header, and writes the complete binary file with an 8-byte little-endian header length prefix.
