Gemma 4’s Apache 2.0 license is the most permissive of Google’s Gemma releases, removing prior restrictions on commercial use and making it legally safe to embed in products, fine-tune for proprietary domains, and deploy alongside open-source infrastructure like Milvus without license entanglement.
Previous Gemma models required agreeing to a custom license that imposed usage restrictions, creating legal uncertainty for enterprises building commercial products. Apache 2.0 removes that friction — you can integrate Gemma 4 as an embedding model or generation backbone in your Milvus-powered pipeline and distribute the resulting application without special licensing review.
For self-hosted Milvus deployments, this matters in several practical ways. You can fine-tune Gemma 4’s E2B or E4B variants on proprietary data to generate domain-specific embeddings, store those embeddings in Milvus, and ship the resulting search capability as part of a commercial product — all under a well-understood open-source license. The combination of Apache 2.0 Gemma 4 and Apache 2.0 Milvus gives you a fully open-source stack from embedding generation through vector retrieval without any license compatibility concerns.
