Meta-Llama-3.1-8B-Instruct-rtn-w4a16

Round-to-nearest 4-bit weight quantization (w4a16, no calibration data) of meta-llama/Meta-Llama-3.1-8B-Instruct (calibration-free). One of the 30 compressed configurations released with the ICAIF '26 paper Damage Predicts Recovery: When Calibration Data Matters in Compressing Financial LLMs, which studies when post-training compression of financial LLMs needs domain-matched calibration data.

Code, calibration corpora, evaluation suite and all other configurations: github.com/JunyiYe/finance-ptc-calibration - full collection: Financial LLM Compression & Calibration (ICAIF 2026).

Usage

The checkpoint is in compressed-tensors format and loads directly in vLLM, or in transformers:

from transformers import AutoModelForCausalLM, AutoTokenizer
model = AutoModelForCausalLM.from_pretrained("jy395/Meta-Llama-3.1-8B-Instruct-rtn-w4a16", device_map="auto")
tokenizer = AutoTokenizer.from_pretrained("jy395/Meta-Llama-3.1-8B-Instruct-rtn-w4a16")

To reproduce the paper's evaluation (ten financial tasks), see the evaluation suite in the code release.
