The text embedding set trained by Jina AI, Finetuner team.
Intended Usage & Model Info
jina-embeddings-v2-base-zh is a Chinese/English bilingual text embedding model supporting 8192 sequence length. Our model has the same architecture as jina-embeddings-v2-base-en and has 161 million parameters.
We have designed it for high performance in cross-language applications and trained it specifically to support mixed Chinese-English input without bias.
| Model | Language | Max Sequence Length | Dimension | Model Size |
|---|---|---|---|---|
| jina-embeddings-v2-base-en | English | 8192 | 768 | 0.27GB |
| jina-embeddings-v2-base-zh | Chinese and English | 8192 | 768 | 0.32GB |
You can use the embedding model either via the Jina AI's Embedding platform, AWS SageMaker or in your private deployments.
Usage Jina Embedding API
The following code snippet shows the usage of the Jina Embedding API:
