Model card
Llama 3.1 405B represents a significant shift in the open-weights landscape, offering frontier-level performance that rivals top-tier proprietary models. For developers, its primary value lies in its massive scale, which enables complex reasoning, sophisticated multilingual support, and high-fidelity code generation. Unlike smaller models, the 405B variant is designed for heavy-duty production workloads where precision is non-negotiable. It is particularly effective as a 'teacher model' for synthetic data generation to distill knowledge into smaller, more efficient models. Integration is streamlined via standard inference frameworks, though its footprint requires substantial VRAM or distributed deployment across multiple GPUs. It provides a viable alternative for teams needing full control over their weights without sacrificing the capabilities of a state-of-the-art LLM.
Model files and versions
Download this model
We recommend using the ModelScope CLI or SDK. Install ModelScope first, then choose a full snapshot, single file, SDK or Git LFS workflow.
meta-llama/Llama-3.1-405BInstall the CLI and SDK dependency before downloading.
pip install modelscopeDownload the complete weights, configuration and model card.
modelscope download --model meta-llama/Llama-3.1-405BREADME.md is used as an example; replace it with another repository file when needed.
modelscope download --model meta-llama/Llama-3.1-405B README.md --local_dir ./dirUseful in Python projects and automation scripts.
from modelscope import snapshot_download
model_dir = snapshot_download('meta-llama/Llama-3.1-405B')Make sure Git LFS is installed correctly.
git lfs install
git clone https://www.modelscope.cn/meta-llama/Llama-3.1-405B.gitFetch the repository structure first, then pull large files when needed.
