T5Gemma: A new collection of encoder-decoder Gemma models

Google's T5Gemma is a new set of encoder-decoder language models adapted from Gemma 2. These models excel at summarization and translation, offering improved performance and efficiency over decoder-only models. T5Gemma achieves comparable or better results on benchmarks like SuperGLUE and GSM8K, with flexible configurations for quality-efficiency trade-offs. Google has released multiple T5Gemma checkpoints, including pretrained and instruction-tuned versions in various sizes, to support ongoing research in large language models.
