We are excited to announce that, as of 05 March 2026, the **OpenIFS model** from ECMWF is available under the **Apache 2.0 open-source licence**.

This is a big step forward for our model’s user community. Moving to Apache 2.0 means you are now free to use, modify, and share the model under the terms of the open-source licence, making it much easier to collaborate, experiment, and build new developments on top of OpenIFS.

The official open-source release of the ECMWF OpenIFS model is available here:

[https://github.com/ecmwf-ifs/openifs](https://github.com/ecmwf-ifs/openifs)

Please note that the GitHub repository above is the only location where the open-source OpenIFS model is now available and where new model versions will be released.

**Previous versions of OpenIFS** (downloaded from the tarball download site, the ftp server, or ECMWF Bitbucket) that have so far been used under the ECMWF OpenIFS software licence agreement **are not open source and should be replaced** with this new GitHub release if you want to benefit from the open-source licence, future new model releases, and ongoing contributions.

We look forward to seeing the expanded opportunities this change will bring to model’s user community.

The OpenIFS Team at ECMWF
