Llama-3.1-5B-40pct-Compressed-8B-EN-V1

Llama-3.1-5B — 40% Compressed from Llama-3.1-8B (English)

Built with Llama. This repository is part of the Efficient and Robust AI System (E-AI) Project by Vincent-Daniel Yun. This model is a compressed edition of meta-llama/Llama-3.1-8B with 13 of 32 transformer layers removed (19 layers remain, ≈5.19B parameters), recovered training-free. It is a base (non–chat-tuned) model.

⚠️ Language: English-focused. Use as a discrimination / classification engine (classification, reading comprehension, domain QA, judging, safety screening) — open-ended long-form generation is degraded by compression (see PPL). For factual questions use retrieval (RAG).

About E-AI

Modern AI is powerful but heavy. State-of-the-art models are enormous and their inference is slow. The E-AI (Efficient-AI) project builds compact yet capable AI — making every model lightweight and fast, and keeping multi-agent teams reliable even when some members fail — so AI can assist people in urgent, high-stakes moments.

Method

The pruning method and the training-free recovery method are proprietary, undisclosed methods created by Vincent-Daniel Yun and are not released. Only the resulting model is shared.

Results (measured, full test sets)

PPL on 2048-token context (↓ better); downstream & MMLU are 0-shot via lm-eval-harness (↑ better).

Task-suitability (vs base Llama-3.1-8B)

Where this compressed model stays close to the base on discrimination tasks (full test sets):

(Discrimination is largely preserved; generation/PPL degrades with compression. Yes/No safety-F1 benchmarks are omitted as the non-chat base is poorly calibrated for them.)

Efficiency (measured, fp16, single GPU)

Usage — Transformers

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
m = AutoModelForCausalLM.from_pretrained("daniel-eai/Llama-3.1-5B-40pct-Compressed-8B-EN-V1", trust_remote_code=True, dtype=torch.float16, device_map="cuda")
tok = AutoTokenizer.from_pretrained("daniel-eai/Llama-3.1-5B-40pct-Compressed-8B-EN-V1", trust_remote_code=True)
ids = tok("The capital of France is", return_tensors="pt").to("cuda")
print(tok.decode(m.generate(**ids, max_new_tokens=20)[0]))

trust_remote_code=True is required (custom decoder layer in modeling_llama_recovered.py).
