Google DeepMind has introduced T5Gemma, a new family of encoder-decoder large language models derived from their existing Gemma 2 models. This adaptation technique allows for flexible combinations of encoder and decoder sizes, enabling a better balance between model quality and inference efficiency. Experiments show T5Gemma models achieve performance comparable to or exceeding their decoder-only Gemma counterparts across various benchmarks, offering significant advantages in speed and accuracy for tasks like math reasoning and reading comprehension.
