No platform support is stated in the record.
Suggest a correction - Where it runs
- Local machine
Open-weight models are run by the user, not served by the vendor.
Suggest a correction - Works offline

Local execution implies the model can run without a network once downloaded, but the vendor does not state this in the record.
Suggest a correction - Official service region
- Global
Mirrors the availability field already on the record ("global").
Suggest a correction - Public API
- Yes
The record mentions an API surface.
Suggest a correction - Licence
- DeepSeek-V3: MIT (repository code); DeepSeek Model License (Base and Chat weights)
Read on the DeepSeek-V3 model card: "This code repository is licensed under the MIT License. The use of DeepSeek-V3 Base/Chat models is subject to the Model License." The repository LICENSE-CODE file is the MIT text and LICENSE-MODEL is the DeepSeek License Agreement v1.0 (23 October 2023). The value is scoped to DeepSeek-V3; other DeepSeek releases were not read.
Suggest a correction - Commercial use
- Permitted
Scope: the DeepSeek-V3 model card states the V3 series (Base and Chat) supports commercial use; the DeepSeek Model License still imposes use-based restrictions. Commercial terms for other DeepSeek releases were not read.
Suggest a correction - Interface languages
- Not recorded
No vendor page read in this pass states the product's own interface languages; the key exists so the field can be answered later rather than left absent.

Licence: MIT for the DeepSeek-V3 repository code Verified 2026-10-13 raw.githubusercontent.com ↗
Applies to: Applies to the code in deepseek-ai/DeepSeek-V3 (LICENSE-CODE), not to the model weights and not to other DeepSeek releases.
LICENSE-CODE is the MIT text ("MIT License / Copyright (c) 2023 DeepSeek"); the model card repeats that the code repository is licensed under the MIT License.

Licence: DeepSeek Model License for the DeepSeek-V3 Base and Chat weights Verified 2026-10-13 raw.githubusercontent.com ↗
Applies to: Applies to the DeepSeek-V3 release only; other DeepSeek releases keep their own terms and were not read here.
LICENSE-MODEL is the "DEEPSEEK LICENSE AGREEMENT, Version 1.0, 23 October 2023". The model card says the Base/Chat models are subject to the Model License and that the V3 series supports commercial use. The licence carries use-based restrictions (Attachment A) that must be passed on to downstream users.

Licence: Licence terms are set per release, not for the DeepSeek family as a whole Our inference
Applies to: Scope statement: only the DeepSeek-V3 licences were read for this record.
The record keeps code terms and weight terms separate and names the release they were read from, so the values above are not presented as covering other DeepSeek models.

In the DeepSeek-V3 release read for this record, the repository code is MIT while the Base and Chat weights are under the DeepSeek Model License, which supports commercial use subject to its use-based restrictions. Other DeepSeek releases were not read. The chat assistant and API are hosted services, not downloads.
Who develops DeepSeek?

What are DeepSeek's reasoning models?
The DeepSeek R series is trained to reason step by step before answering, targeting math, coding, and analysis tasks.
What does the DeepSeek record not confirm?

Recorded instead are a pricing page and, for the DeepSeek-V3 release, its licences: MIT for the repository code and the DeepSeek Model License for the Base and Chat weights. Licences for other DeepSeek releases are not recorded.
