Usage

python

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "AvoCahDoe/llama-2-13b-rlmpq-conservative"

model = AutoModelForCausalLM.from_pretrained(repo, torch_dtype="float16")
tokenizer = AutoTokenizer.from_pretrained(repo)

Scenario	Avg bits	Compression	WikiText-2 PPL
Aggressive	3.75	4.2667x	4.5724
Balanced	4.4	3.6364x	4.4797
Extreme Survival	2.775	5.7658x	6.1148

Method

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