 RETVec is trained to be resilient against character-level manipulations including insertion, deletion, typos, homoglyphs, LEET substitution, and more. The RETVec model is trained on top of a novel character encoder which can encode all UTF-8 characters and words efficiently. Thus, RETVec works out-of-the-box on over 100 languages without the need for a lookup table or fixed vocabulary size. Furthermore, RETVec is a layer, which means that it can be inserted into any TF model without the need for a separate pre-processing step.
 
-RETVec's speed and size (~200k instead of millions) also makes it a great choice for on-device and web use cases. It is [natively supported in TensorFlow Lite](notebooks/tf_lite_retvec.ipynb) via [custom ops in TensorFlow Text](https://www.tensorflow.org/text/api_docs/python/text/utf8_binarize), and we provide a Javascript implementation of RETVec which allows you to deploy web models via TensorFlow.js.
