Open Model License Agreement (OMLA) v1.0 — DRAFT
Copyright (c) 2025 Open Model Licensing Association

Permission is hereby granted, free of charge, to any person obtaining a copy of this AI model and associated files (the "Model"), to use, copy, modify, merge, publish, distribute, and/or create derivative works of the Model (collectively "Use"), subject to the terms and conditions below.

1. DEFINITIONS
"Model" means the AI model weights, parameters, datasets, and documentation provided under this License.
"Derivative Model" means any model based on or derived from the Model, including fine‑tunes, LoRAs, merges, or adaptations.
"Creator(s)" means the individual(s) or entity(ies) designated to receive royalties for a Model.
"Commercial Use" means any Use intended for or resulting in monetary gain or commercial advantage, including charging for access to the Model, using it in paid services, or selling outputs substantially generated by it.
"Revenue" means gross receipts from Commercial Use minus reasonable direct costs of model inference/serving for that use (e.g., compute). General overhead is excluded from deduction.

2. GRANT OF RIGHTS
Subject to this License, you may Use the Model and any Derivative Model for any purpose, worldwide and perpetually, including personal, research, and commercial purposes. No fees or royalties are required for non‑commercial Use. Commercial Use is conditioned on Section 4.

3. ATTRIBUTION & NOTICES
When publishing or distributing the Model or a Derivative Model, retain all author notices and this License. Identify modifications made. Attribution in public materials is encouraged.

4. ROYALTY SHARING FOR COMMERCIAL USE
4.1 Rate. For each Commercial Use, allocate thirty percent (30%) of Revenue as the royalty pool.
4.2 Upstream Distribution. One hundred percent (100%) of the royalty pool is paid to Creators of upstream/base Models, in proportion to declared contribution percentages. Implementers of the current Model do not take from this pool.
4.3 Derivative Contribution Cap. For Derivative Models, the creator’s self‑attributed contribution may not exceed fifty percent (50%) of total contributions without approval by the OMLA Board or written consent of upstream Creators.
4.4 Payment Cadence. Royalties should be remitted contemporaneously via automated split payments where feasible; otherwise no less frequently than quarterly, with a simple revenue/expense record.
4.5 Transparency. Use OMLA wallets/smart‑contracts or equivalent auditable mechanisms. Keep reasonable proof of payment.
4.6 Breach. Failure to remit required royalties for Commercial Use is a material breach of this License.

5. OUTPUTS
Outputs generated by the Model belong to the user subject to applicable law. This License does not claim rights in outputs; however, monetization of outputs constitutes Commercial Use of the Model for purposes of Section 4.

6. WARRANTY & LIABILITY
THE MODEL IS PROVIDED “AS IS”, WITHOUT WARRANTY OF ANY KIND. IN NO EVENT SHALL CREATORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY, WHETHER IN CONTRACT, TORT, OR OTHERWISE, ARISING FROM OR IN CONNECTION WITH THE MODEL OR ITS USE.

7. TERMINATION
Rights under this License terminate automatically upon material breach (including non‑payment under Section 4). Cure within thirty (30) days may reinstate rights at Creators’ discretion. Termination does not affect prior recipients in compliance.

8. GOVERNANCE & VERSIONS
This Model is licensed under OMLA v1.0. Future versions may be published; Creators may re‑license at their option. The OMLA Board may issue non‑binding guidelines and approve exceptions under Section 4.3.

9. SEVERABILITY; ENTIRE AGREEMENT
If any provision is unenforceable, the remainder remains in effect. This License constitutes the entire agreement for Use of the Model under OMLA.
