Model card
The gpt-oss-20b model represents a significant milestone for developers seeking a high-performance, open-weight alternative for text generation tasks. Built on a 20-billion parameter architecture, it strikes a pragmatic balance between computational efficiency and deep linguistic reasoning. Unlike massive proprietary models that require expensive API calls, this model is licensed under Apache-2.0, making it ideal for commercial integration and local fine-tuning within your own infrastructure. For engineering teams, this means full control over data privacy and the ability to optimize latency for edge deployment or high-throughput backend services. Whether you are building sophisticated RAG pipelines, automated code assistants, or complex content generation engines, gpt-oss-20b provides a stable, extensible foundation that competes effectively with closed-source counterparts while maintaining a significantly lower operational overhead.
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.
openai/gpt-oss-20bInstall the CLI and SDK dependency before downloading.
pip install modelscopeDownload the complete weights, configuration and model card.
modelscope download --model openai/gpt-oss-20bREADME.md is used as an example; replace it with another repository file when needed.
modelscope download --model openai/gpt-oss-20b README.md --local_dir ./dirUseful in Python projects and automation scripts.
from modelscope import snapshot_download
model_dir = snapshot_download('openai/gpt-oss-20b')Make sure Git LFS is installed correctly.
git lfs install
git clone https://www.modelscope.cn/openai/gpt-oss-20b.gitFetch the repository structure first, then pull large files when needed.
GIT_LFS_SKIP_SMUDGE=1 git clone https://www.modelscope.cn/openai/gpt-oss-20b.gitHow to use
