Usage

from transformers import AutoModelForCausalLM, AutoTokenizer

repo = "AvoCahDoe/llama-2-13b-rlmpq-extreme-survival"

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

Grouped archive (all scenarios in one repo): AvoCahDoe/llama-2-13b-rlmpq

Method

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