What is new in Google Gemma 4 E2B IT is the smallest instruction-tuned Gemma 4 variant, with 2.3 billion effective parameters and 5.1 billion including embeddings. That distinction explains its local-device focus without making E2B a 2B total model.

Apache 2.0 and the compact parameter size mark the checkpoint’s on-device direction. The E stands for effective parameters, not a shortened model name. Gemma 4 E4B IT offers more capacity while keeping the same on-device direction.
