Model card
The paraphrase-MiniLM-L12-v2 is a lightweight, high-performance sentence transformer optimized for mapping sentences to a dense vector space. Unlike general-purpose LLMs, this model is specifically tuned for semantic textual similarity (STS), making it an ideal choice for developers building RAG pipelines, semantic search engines, or clustering systems where latency and resource overhead are critical constraints. It strikes a strong balance between embedding quality and inference speed, delivering performance comparable to much larger models while remaining small enough to deploy on edge devices or CPU-only environments. Integration is straightforward via the sentence-transformers library, allowing for rapid vectorization of large datasets without requiring massive GPU clusters.

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.
sentence-transformers/paraphrase-MiniLM-L12-v2Install the CLI and SDK dependency before downloading.
pip install modelscopeDownload the complete weights, configuration and model card.
modelscope download --model sentence-transformers/paraphrase-MiniLM-L12-v2README.md is used as an example; replace it with another repository file when needed.
modelscope download --model sentence-transformers/paraphrase-MiniLM-L12-v2 README.md --local_dir ./dirUseful in Python projects and automation scripts.
from modelscope import snapshot_download
model_dir = snapshot_download('sentence-transformers/paraphrase-MiniLM-L12-v2')Make sure Git LFS is installed correctly.
git lfs install
git clone https://www.modelscope.cn/sentence-transformers/paraphrase-MiniLM-L12-v2.gitFetch the repository structure first, then pull large files when needed.
