Model overview
`jina-embeddings-v2-base-zh` is a Chinese/English bilingual text **embedding model** supporting **8192 sequence length**. It is based on a BERT architecture (JinaBERT) that supports the symmetric bidirectional variant of ALiBi to allow longer sequence length. We have designed it for high performance in mono-lingual & cross-lingual applications and trained it specifically to support mixed Chinese-English input without bias. Additionally, we provide the following embedding models: `jina-embeddings-v2-base-zh` 是支持中英双语的**文本向量**模型,它支持长达**8192字符**的文本编码。 该模型的研发基于BERT架构(JinaBERT),JinaBERT是在BERT架构基础上的改进,首次将ALiBi应用到编码器架构中以支持更长的序列。 不同于以往的单语言/多语言向量模型,我们设计双语模型来更好的支持单语言(中搜中)以及跨语言(中搜英)文档检索。 除此之外,我们也提供其它向量模型: `mean poooling` takes all token embeddings from model output and averaging them at sentence/paragraph level. It has been proved to be the most effective way to produce high-quality sentence embeddings. We offer an `encode` function to deal with this.

Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
