In tandem with our acquisition, we are updating the license of all of our models to Apache 2.0. This means you can now self-serve our models through any inference providers without a commercial license. The different options are all listed in our migration guide.

If you’re using zsearch, ZeroEntropy’s search engine, we recommend following our migration guide to migrate to another vendor.
