 The simplest way to use NLP models in the {{stack}} is through the [`semantic_text` workflow](semantic-search/semantic-search-semantic-text.md). We recommend using this approach because it abstracts away a lot of manual work. All you need to do is create an index mapping to start ingesting, embedding, and querying data. There is no need to define model-related settings and parameters, or to create {{infer}} ingest pipelines. 
 
-{applies_to}`stack: ga 9.1` We recommend using the ELSER model hosted on Elastic Inference Service (EIS) by setting the `inference_id` to `.elser-2-elastic` in your index mapping. For more details, see the ELSER on EIS guide.
