# Built-in NLP models
There are natural language processing models that are available for use in every cluster out-of-the-box. These models are pre-trained which means they don’t require fine-tuning on your own data, making it adaptable for various use cases out of the box. The following models are available:
- [ELSER](https://www.elastic.co/docs/explore-analyze/machine-learning/nlp/ml-nlp-elser) trained by Elastic
- [Jina models](https://www.elastic.co/docs/explore-analyze/machine-learning/nlp/ml-nlp-jina)
- [Elastic Rerank](https://www.elastic.co/docs/explore-analyze/machine-learning/nlp/ml-nlp-rerank)
- [E5](https://www.elastic.co/docs/explore-analyze/machine-learning/nlp/ml-nlp-e5)
- [Language identification](https://www.elastic.co/docs/explore-analyze/machine-learning/nlp/ml-nlp-lang-ident)
