 ## Intended Usage & Model Info
 
-`jina-embedding-s-en-v2` is an English, monolingual embedding model supporting 8k sequence length.
-It is based on a Bert architecture that supports the symmetric bidirectional variant of ALiBi to support longer sequence length.
-The backbone Jina Bert Small model is pretrained on the C4 dataset.
-The model is further trained on Jina AI's collection of more than 40 datasets of sentence pairs and hard negatives.
+`jina-embedding-s-en-v2` is an English, monolingual **embedding model supporting 8192 sequence length**.
+It is based on a Bert architecture (Jina Bert) that supports the symmetric bidirectional variant of [ALiBi](https://arxiv.org/abs/2108.12409) to support longer sequence length.
+The backbone `jina-bert-s-en-v2` is pretrained on the C4 dataset.
+The model is further trained on Jina AI's collection of more than 400 millions of sentence pairs and hard negatives.
 These pairs were obtained from various domains and were carefully selected through a thorough cleaning process.
 
-The embedding model was trained using 512 sequence length, but extrapolates to 8k sequence length thanks to ALiBi.
+The embedding model was trained using 512 sequence length, but extrapolates to 8k sequence length (or even longer) thanks to ALiBi.
 This makes our model useful for a range of use cases, especially when processing long documents is needed, including long document retrieval, semantic textual similarity, text reranking, recommendation, RAG and LLM-based generative search,...
 
-This model has 33 million parameters, which enables lightning-fast and memory efficient inference on long documents, while still delivering impressive performance.

 ## Plans
-The development of new multilingual models is currently underway. We will be targeting mainly the German and Spanish languages. The upcoming models will be called `jina-embedding-s/b/l-de/es-v2`.
