DeepSeek Open-Source Availability, Self-Hosting Options, And Deployment Models: Licensing, Practicality, And Cloud Integration
- 9 hours ago
- 3 min read
DeepSeek’s model ecosystem blends open-source code, varying license regimes for weights, and flexible deployment pathways that range from do-it-yourself GPU hosting to managed cloud services. The options and constraints for open access and deployment depend on both the specific DeepSeek model line and the licensing terms attached to each release.
·····
DeepSeek-R1 And Select V3 Releases Offer Fully Open-Source Weights And Code.
DeepSeek-R1 is positioned as fully open, with both the repository and model weights under the MIT License. This permissive license explicitly allows for commercial use, derivative works, and model distillation. Recent checkpoints for DeepSeek-V3 and DeepSeek-V3.1 have also been released under MIT, with Hugging Face repositories containing clear license files for both code and weights.
This level of openness allows researchers and organizations to download, adapt, and run models in local or production environments with minimal licensing friction, provided they comply with MIT’s minimal attribution requirements.

DeepSeek Open-Source Status By Model Line
Model Line | Code License | Weights License | Commercial Use | Distillation Rights |
DeepSeek-R1 | MIT | MIT | Allowed | Explicitly allowed |
DeepSeek-V3.1 | MIT | MIT | Allowed | Allowed |
DeepSeek-V3-0324 | MIT | MIT | Allowed | Allowed |
DeepSeek-Coder-V2 | MIT | Model License* | Allowed* | Paper frames as permissive |
*Some DeepSeek-Coder and older V3 releases use a Model License that includes use restrictions.

Some Model Weights Are Released Under A DeepSeek Model License With Extra Restrictions.
While DeepSeek’s codebase is MIT-licensed, some models—particularly Base/Chat variants of DeepSeek-V3 and DeepSeek-Coder-V2—are released under a “Model License.” This custom license may restrict certain uses, such as service deployment or derivative works, depending on checkpoint and documentation.
Distilled variants of DeepSeek models may also carry licensing conditions inherited from their upstream base models, so careful review of each release’s license file is critical for compliance.
........
DeepSeek Model License Considerations
Model Type | License Regime | Practical Impact |
MIT-only | Fully permissive | Commercial use and modification allowed |
Model License | Use-based restrictions | May restrict service or re-distribution |
Distilled models | Upstream license governs | Some inherited constraints may apply |
Open-weights may still have enforceable usage boundaries.
·····
Self-Hosting Is Supported Via Open Weights, Community Inference Stacks, And Official Demos.
Self-hosting DeepSeek models typically starts by downloading weights from Hugging Face or official mirrors, then running them with an inference engine compatible with large mixture-of-experts (MoE) models. DeepSeek-V3 documentation and repositories provide explicit “run locally” instructions, with support for community runtimes such as SGLang, LMDeploy, and vLLM, as well as an official DeepSeek-Infer Demo.
Organizations can deploy DeepSeek for research or production via DIY GPU servers, or use high-throughput serving stacks and container orchestrators to expose OpenAI-compatible endpoints. Long-context support and mixed precision (BF16, FP8) are common requirements for full performance.

DeepSeek Self-Hosting And Local Deployment Pathways
Method | Stack / Tooling | Suitability |
Community runtimes | SGLang, LMDeploy, vLLM | Flexible, supports large models |
Official demo | DeepSeek-Infer Demo | Quick-start and experimentation |
DIY production stack | Containers, GPU orchestration | Enterprise and research workflows |
Practical local deployment depends on infrastructure and compatibility.
·····
Managed Cloud, Marketplace, And Hosted Trials Expand Enterprise Deployment Choices.
DeepSeek models are also available as managed services on cloud platforms, shifting operational focus from GPU provisioning to API governance and cost management. Google Cloud Vertex AI and Microsoft Azure AI Foundry catalog list DeepSeek among their managed or self-deployed models, allowing organizations to use DeepSeek in compliant, scalable environments.
Some platforms offer “hosted trial” access to DeepSeek models, adding another license layer governed by the platform’s own community or enterprise terms.
........
DeepSeek Cloud And Marketplace Deployment Models
Platform | Deployment Option | License Context |
Google Cloud Vertex AI | Managed API, self-deploy | Google/Vertex service terms |
Azure AI Foundry | Model catalog, easy deploy | Azure service terms |
Hosted trial platforms | API access under trial | Platform’s license plus model license |
Cloud integration simplifies enterprise adoption and compliance.
·····
Licensing Nuances And Compliance Determine Open-Source Practicality.
The decision to self-host or use managed DeepSeek services depends on licensing, compliance, and operational needs. MIT-licensed releases maximize flexibility, while Model License versions require careful legal review. Regulatory and data handling considerations may lead organizations to prefer self-hosting or trusted cloud deployments for sensitive workloads.
