Usage
from transformers import AutoModelForCausalLM, AutoTokenizer
repo = "AvoCahDoe/qwen2-5-7b-rlmpq-high-fidelity"
model = AutoModelForCausalLM.from_pretrained(repo, torch_dtype="float16")
tokenizer = AutoTokenizer.from_pretrained(repo)

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