T5Gemma Base PrefixLM Instruction-Tuned

Yes, it is 2025 and we are getting a modern version of T5 (Text-To-Text Transfer Transformer, 2019, encoder-decoder models). Some of the versions use Gemma 2 (2B and 9B) for the decoder part, while others are using the same sizes as mT5 and are trained from scratch, allowing an easy switch between old deployments still using T5 and those new versions. Considering that T5 still rakes in millions of downloads each month, those models could end up being similarly popular. However, these new versions are licensed under Gemma, not under Apache 2.0 like the original T5 models.
