Converts a custom Hugging Face checkpoint into a cross‑platform LiteRT IR in under a minute, runs quantization in ~40 seconds, and pushes the packaged model to a phone to run on-device GPU successfully; workflow uses the LiteRT Torch toolchain, Edge Quantizer, and LiteRT runtime with PyTorch FX lowering and an MLIR backend, supporting CPU/GPU/NPUs and producing a single TRM bundle (model, tokenizer, metadata). Demonstrates enabling QWEN0.6 in 20 minutes and end‑to‑end verification via terminal or Colab.
