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 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.
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:
curl https://api.jina.ai/v1/embeddings \
-H "Content-Type: application/json" \
-H "Authorization: Bearer jina_xxxxxxx" \
-d '{
"input": ["你的输入可以是纯中文", "or purely in English", "or like mixture of 中文 and 英文"],
"model": "jina-embeddings-v2-base-zh"
}'
