Usage
from transformers import AutoModelForCausalLM, AutoTokenizer

Method
- Phase 3 — PPO agent assigns per-layer bit widths under the Balanced reward target.
- Phase 4 — Policy replayed on real weights; WikiText-2 perplexity validates quality.
- Export — Fake-quantized FP16 weights compatible with Hugging Face Transformers.
