EmbeddingGemma 2 开源：Apache 2.0 许可确立嵌入模型标准
Google 发布 EmbeddingGemma 2，采用 Apache 2.0 许可证开源。该举措解决了专有嵌入模型因供应商停服导致向量数据失效的风险，确立了“云端托管+本地备份”的混合部署最佳实践。

My comment on EmbeddingGemma 2 — Hacker News.
I really appreciate that EmbeddingGemma 2 is under the Apache 2.0 license.
For embedding models in particular, I don't think it makes sense to use a closed, proprietary, hosted-only model.
Most applications of embedding models involve calculating thousands or even millions of embedding vectors and storing them for later comparison.
If your model is proprietary, the vendor is likely someday going to decide to stop offering that model. They'll have a better model to replace it, but you still need to pay to re-calculate those millions of stored existing vectors.
Notably, I don't want to host the model myself. I'd much rather pay a provider for a hosted model while knowing that if they ever stop hosting it I can run the open weights version myself - or find another vendor who can do that for me.
