Nano Banana 2 is released under the Apache License, Version 2.0. This is a widely adopted permissive open-source license that allows you to use, modify, and distribute the software freely, including in proprietary commercial products. The key requirement is attribution: you must retain copyright notices and include a copy of the license when distributing the software or derivative works. Unlike some other open-source licenses, Apache 2.0 does not require you to open-source modifications you make, which makes it compatible with closed-source commercial use.
Apache 2.0 also includes an explicit patent grant. Contributors to the project grant users a perpetual, worldwide, royalty-free license to any patents they hold that are necessarily infringed by the software. This provision gives enterprises using the library additional legal clarity, which is one reason Apache 2.0 is commonly chosen for infrastructure and developer tooling projects. If a contributor later asserts a patent claim against a user of the software, that user’s license terminates, which creates a practical deterrent against such behavior within the project ecosystem.
If you are evaluating Nano Banana 2 for use in an organization with formal open-source review processes, the Apache 2.0 license is generally pre-approved by legal teams familiar with standard open-source licenses. The project provides a LICENSES file at the root of the repository listing both the primary license and the licenses of all included third-party dependencies. This makes it straightforward to produce accurate open-source compliance documentation for internal audits or distribution requirements.
