| PiCo-1B Open RAIL-M License |
| Version 1.0, dated June 25, 2026 |
|
|
|
|
| Section I: PREAMBLE |
|
|
| This Open RAIL-M License Agreement was created for PiCo-1B, a machine-learning |
| model developed by ArcOffical. This license is generally applicable to any |
| machine-learning Model. |
|
|
| This License Agreement strives for both the open and responsible Use of the |
| accompanying Model. Openness here is understood as enabling users of the Model |
| on a royalty-free basis to Use it, modify it, and even share commercial versions |
| of it. Use restrictions are included to prevent misuse of the Model. |
|
|
| This License Agreement governs the Use of the Model and Modifications of the |
| Model. Even though downstream derivative versions of the model could be released |
| under different licensing terms, the latter will always have to include — at |
| minimum — the same use-based restrictions as the ones in the original license. |
|
|
| The development and use of artificial intelligence ("AI") does not come without |
| concerns. The world has witnessed how AI techniques may, in some instances, |
| become risky for the public in general. These risks come in many forms, from |
| racial discrimination to the misuse of sensitive information. ArcOffical |
| believes in the intersection between open and responsible AI development; thus, |
| this License aims to strike a balance between both in order to enable |
| responsible open-science in the field of AI. |
|
|
| This License governs the use of the Model (and its Derivatives) and is informed |
| by the model card associated with the Model. |
|
|
| NOW THEREFORE, You and Licensor agree as follows: |
|
|
|
|
| Section II: DEFINITIONS |
|
|
| 1.1 "Complementary Material" means the accompanying source code and scripts used |
| to define, run, load, benchmark or evaluate the Model, and used to prepare data |

| "submitted" means any form of electronic, verbal, or written communication sent |
| to the Licensor or its representatives, including but not limited to |

| other model, in order to cause the other model to perform similarly to the |
| Model, including — but not limited to — distillation methods entailing the use |
| of intermediate data representations or methods based on the generation of |
| synthetic data by the Model for training the other model. |
|
|
| 1.6 "Distribution" means any transmission, reproduction, publication or other |
