T5Gemma 2: Google’s Breakthrough in Multimodal Long-Context AI

T5Gemma 2: Breakthroughs and Applications of the Next-Generation Encoder-Decoder Model In the fast-paced world of artificial intelligence, encoder-decoder architectures have long stood out as a cornerstone of research and practical application, thanks to their unique strengths in tasks like text generation, translation, and question answering. In December 2025, Google unveiled T5Gemma 2—not just an upgrade to the previous T5Gemma, but a next-generation encoder-decoder model built on the Gemma 3 framework, marking the first integration of multimodal capabilities and long-context processing in this model family. This article will take you on a comprehensive journey through T5Gemma 2, covering its background, core …
