Model card
For developers looking to bridge the gap between proprietary performance and open-source flexibility, gpt-oss-120b offers a significant scaling milestone. Built on the Apache 2.0 license, this model is designed for high-throughput text generation tasks where data sovereignty and local deployment are non-negotiable. While many large-scale models remain locked behind closed APIs, the 120B parameter architecture provides the reasoning depth required for complex instruction following, code generation, and sophisticated RAG pipelines. Integration is straightforward via the Hugging Face ecosystem, making it compatible with standard inference engines like vLLM or Text Generation Inference (TGI). Compared to smaller distilled models, it excels in nuanced linguistic tasks and multi-step logic, though it requires substantial VRAM for optimal quantization and deployment. It is an ideal candidate for enterprises building private, fine-tunable LLM infrastructures without the recurring latency or privacy concerns of third-party endpoints.

pip install modelscopeDownload the complete weights, configuration and model card.
modelscope download --model openai/gpt-oss-120bREADME.md is used as an example; replace it with another repository file when needed.
modelscope download --model openai/gpt-oss-120b README.md --local_dir ./dirUseful in Python projects and automation scripts.
from modelscope import snapshot_download
model_dir = snapshot_download('openai/gpt-oss-120b')Make sure Git LFS is installed correctly.
