unsloth/llama-2-7b — lems search — 0.6 target ratio

This model was compressed using kfac_svd with lems rank search starting from unsloth/llama-2-7b as base model. You may check out our publication and project page for details on kfac-svd and our LEMS rank search.

Update (2026-10-23). The weights were recomputed with the fixed KFAC-SVD implementation. The first release of the code (v1, used for the published paper) whitened the output side of each weight with the Cholesky factor L of G = LLᵀ instead of Lᵀ. The correct version was described by the algorithm in the paper already. Those weights, which the paper's tables report, remain available as revision v1-paper: AutoModelForCausalLM.from_pretrained("MoritzMo123/kfac-svd_lems_llama-2-7b_0.6", revision="v1-paper", trust_remote_code=True).

Compression Details

Metric	Value
Base Model	`unsloth/llama-2-7b`
Method	`kfac_svd`
Search Method	`lems`
Target Ratio	0.6
Compression Metric	`params`
Recommended Dtype	`float16`
Compressed Layers	175
Total Parameters	4,147,615,919

Usage

The checkpoint records its recommended dtype in config.json; no explicit torch_dtype argument should be needed with this remote-code wrapper. For standard Transformers models, torch_dtype="auto" is the portable fallback.

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "MoritzMo123/kfac-svd_lems_llama-2-7b_0.6",
    trust_remote_code=True,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("MoritzMo123/kfac-svd_lems_llama-2-7b_0.6")

inputs = tokenizer('Hello, ', return_tensors="pt").to(model.device)
outputs = model.generate(**inputs, max_new_tokens=50)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
