From-Scratch Safetensors & GGUF Weight Loader with Lazy Memory-Mapped Tensor Streaming and Q4_0/Q8_0 Dequantization in Pure Python
A step‑by‑step guide to creating a lightweight, lazy‑evaluated weight loader that streams safetensors and GGUF tensors, applies Q4_0/Q8_0 dequantization, and can be dropped into any inference pipeline.
