+ # sentence-transformers/sentence-t5-xxl
13
+
14
+ This is a [sentence-transformers](https://www.SBERT.net) model: It maps sentences & paragraphs to a 768 dimensional dense vector space. The model works well for sentence similarity tasks, but doesn't perform that well for semantic search tasks.
15
+
16
+ This model was converted from the Tensorflow model [st5-11b-1](https://tfhub.dev/google/sentence-t5/st5-11b/1) to PyTorch. When using this model, have a look at the publication: [Sentence-T5: Scalable sentence encoders from pre-trained text-to-text models](https://arxiv.org/abs/2108.08877). The tfhub model and this PyTorch model can produce slightly different embeddings, however, when run on the same benchmarks, they produce identical results.
17
+
18
+ The model uses only the encoder from a T5-11B model. The weights are stored in FP16.
19
+
20
+
21
+ ## Usage (Sentence-Transformers)
22
+
23
+ Using this model becomes easy when you have [sentence-transformers](https://www.SBERT.net) installed:
24
+
25
+ ```
26
+ pip install -U sentence-transformers
27
+ ```
28
+
29
+ Then you can use the model like this:
30
+
31
+ ```python
32
+ from sentence_transformers import SentenceTransformer
33
+ sentences = ["This is an example sentence", "Each sentence is converted"]
34
+
35
+ model = SentenceTransformer('sentence-transformers/sentence-t5-xxl')
36
+ embeddings = model.encode(sentences)
37
+ print(embeddings)
38
+ ```
39
+
40
+ The model requires sentence-transformers version 2.2.0 or newer.
41
+
42
+ ## Evaluation Results
43
+
44
+ For an automated evaluation of this model, see the *Sentence Embeddings Benchmark*: [https://seb.sbert.net](https://seb.sbert.net?model_name=sentence-transformers/sentence-t5-xxl)
