## Use cases

- [Commercial use of licensed digital assets](https://www.a2ally.com/use-cases/commercial-use) — May an agent acquire and commercially exploit this asset? a2ally checks the controlling terms' reviewed profile for the commercial_use permission and any prohibition before any purchase.
- [Using assets for AI model training](https://www.a2ally.com/use-cases/model-training) — Training use is a distinct right from inference. a2ally assesses model_training separately: prohibited training returns BLOCK, undocumented training INSUFFICIENT_EVIDENCE, and training under licenses whose conditions may or may not reach a trained model HUMAN_REVIEW. Permission is never assumed.
- [Using assets at inference time](https://www.a2ally.com/use-cases/model-inference) — Runtime/inference use (retrieval, display, generation context) assessed against the reviewed profile independently of training rights.
- [Redistributing licensed assets](https://www.a2ally.com/use-cases/redistribution) — Passing the asset (or copies) to third parties requires an explicit documented redistribution permission in the controlling terms.
- [Modifying and creating derivatives](https://www.a2ally.com/use-cases/modification) — Modification/derivative-work rights are checked against the reviewed profile; duties such as attribution are surfaced as required next actions.
- [Sublicensing rights to others](https://www.a2ally.com/use-cases/sublicensing) — Granting others rights under the license. Creative Commons and GNU licenses do not allow it; MIT and Apache 2.0 do. a2ally returns BLOCK where the license prohibits it.
- [Deploying assets in production systems](https://www.a2ally.com/use-cases/deployment) — Using an asset in a live product or service. Assessed against the license's grant and duties; deploying adapted material counts as sharing it, which NoDerivatives licenses do not allow.
- [Attribution duties](https://www.a2ally.com/use-cases/attribution) — Where a profile carries an attribution duty, assessments flag attribution planning as a required next action before use.
