+AI2 ImpACT License – Low Risk Artifacts
+==========================================
+
+### Version 1.0
+
+This AI2 ImpACT License for Low Risk Artifacts (“LR Agreement”) is between The Allen Institute for Artificial Intelligence (“AI2”) and any individual or entity who purchases, downloads, installs, logs into, accesses or otherwise uses any ”low risk” Artifacts that refer to this LR Agreement, including any other person or entity that an individual purports to represent, be the agent of, or otherwise act on behalf of (collectively, “You”).
+
+By clicking or taking similar action to accept this LR Agreement, or by accessing or using any Artifacts licensed under this LR Agreement, You agree to all the terms and conditions herein. You represent and warrant that You are at least 18 years old and have the full legal right and authority to enter into this LR Agreement and bind any employer or entity that You are acting on behalf of. If You do not agree or have the requisite authority, You have no right to access or use any Artifacts and must immediately cease any existing use.
+
+A human-friendly summary of the legal text can be found [here](http://allenai.org/impact-license).
+
+1. **DEFINITIONS**.
+
+    1. “**Artifact(s)**” means collectively and individually, anything used to build or apply a Model that is licensed by AI2 pursuant to this LR Agreement, such as weights or Data and any Derivatives of the original Artifact.
+
+    2. “**Code**” means a text listing of commands to be compiled or assembled into an executable computer program.
+
+    3. “**Data**” means the datasets created and/or compiled by AI2 to pretrain, train or fine-tune a Model.

+
+        2. all derivative works created from the Data that are considered copyrighted works under U.S. copyright laws.
+
+    5. “**Derivatives**” means anything that is based on or derived from any Artifact within the meaning of applicable U.S. copyright laws; including specifically and without limitation Model Derivatives and Data Derivatives
+
+    6. “**Distribute**” or “**Distribution**” means any transmission, reproduction, publication, public display, or other sharing of the Artifacts to a Third party by any means, including as a hosted service made available by electronic or other remote means - e.g. API-based or web access.

+        1. all modifications to the Model; and/or
+
+        2. any other model which is created or initialized by transfer of patterns of the weights, parameters, activations or output of the Model, to the 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.
+
+    9. “**Term**” means the period of time starting from the date You access or use any Artifacts until this LR Agreement is terminated in accordance with **Section 4**.
+
+    10. “**Third Party**” means any party other than You or AI2.

+
+    3. **Derivative Impact Reports**. AI2 seeks to encourage transparency around Derivatives through the use of Derivative Impact Reports, available [here](http://allenai.org/impact-license). Before releasing a Model Derivative or Data Derivative, You will complete a Derivative Impact Report and will publish, post, or make available the results of the Derivative Impact Report to the general public without imposing any direct or indirect restrictions, conditions or barriers to access, such as a paywall, fee, subscription, account, or requirement to submit personal information. You agree that AI2 may publish, post, or make available the information in Your Derivative Impact Report for review by the general public.

+
+        2. You acknowledge that Derivative Impact Reports are not intended to penalize any good faith disclosures about Derivatives. Accordingly, if You initiate or participate in any lawsuit or other legal action against a Third Party based on information in such Third Party’s Derivative Impact Report, then this LR Agreement will terminate immediately as of the date such lawsuit or legal action is filed or commenced.
+
+    4. **Use-Based Restrictions**. You will not use any Artifacts or Derivatives in connection with any Use-Based Restrictions, including without limitation, creating any content with, finetuning, updating, running, training, evaluating and/or reparametrizing a Model.
