Choosing a licence
The licence says what others may do with your resource. If unsure: MIT for code or a configuration, CC BY 4.0 for a text, dataset or context.
| Licence | Commercial use | Credit the author | Modify | Same licence |
|---|---|---|---|---|
| MIT | Yes | Yes | Yes | No |
| Apache 2.0 | Yes | Yes | Yes | No |
| CC BY 4.0 | Yes | Yes | Yes | No |
| CC BY-SA 4.0 | Yes | Yes | Yes | Yes |
| CC BY-NC 4.0 | No | Yes | Yes | No |
| CC0 (public domain) | Yes | No | Yes | No |
| Proprietary | No | — | No | — |
| No licence | No | — | No | — |
MIT
Code, tools, prompts and configs: the simplest, most permissive software licence.
Can be duplicated
Apache 2.0
Like MIT, plus patent protection. Common for models (Mistral, for example).
Can be duplicated
CC BY 4.0
Texts, datasets and contexts: anything goes as long as the author is credited.
Can be duplicated
CC BY-SA 4.0
Like CC BY, but modified versions must keep the same licence (share alike).
Can be duplicated
CC BY-NC 4.0
Free reuse but no commercial use: share without a company profiting from it.
Can be duplicated
CC0 (public domain)
You waive all rights: anyone can do anything, without even crediting you.
Can be duplicated
Proprietary
Your own terms: other members must ask you before any reuse.
No duplication
No licence
By default nothing is allowed: others can read the resource but not reuse it. Best avoided.
