ModelScope is a big repository of the models and datasets.
This page covers how to use the modelscope ecosystem within LangChain. It is broken into two parts: installation and setup, and then references to specific modelscope wrappers.

​
Installation

pip install -U langchain-modelscope-integration
Head to ModelScope to sign up to ModelScope and generate an SDK token. Once you’ve done this set the MODELSCOPE_SDK_TOKEN environment variable: 
export MODELSCOPE_SDK_TOKEN=<your_sdk_token>

​
Chat Models

ModelScopeChatEndpoint class exposes chat models from ModelScope. See available models here. 
from langchain_modelscope import ModelScopeChatEndpoint

llm = ModelScopeChatEndpoint(model="Qwen/Qwen2.5-Coder-32B-Instruct")
llm.invoke("Sing a ballad of LangChain.")

​
Embeddings

ModelScopeEmbeddings class exposes embeddings from ModelScope. 
from langchain_modelscope import ModelScopeEmbeddings

embeddings = ModelScopeEmbeddings(model_id="damo/nlp_corom_sentence-embedding_english-base")
embeddings.embed_query("What is the meaning of life?")

​
LLMs

ModelScopeLLM class exposes LLMs from ModelScope. 
from langchain_modelscope import ModelScopeLLM

llm = ModelScopeLLM(model="Qwen/Qwen2.5-Coder-32B-Instruct")
llm.invoke("The meaning of life is")
