Google DeepMind releases the Gemma 4 open model family

Gemma 4: Byte for byte, the most capable open models

Google DeepMind released Gemma 4, which it calls its most intelligent open model yet, aimed at advanced reasoning and agentic workflows under an Apache 2.0 license. The family comes in four sizes: E2B, E4B, 26B MoE and 31B Dense. The 31B ranks 3rd among open models on the Arena AI text leaderboard, and the 26B ranks 6th.

Why it matters: Gemma 4 is Apache 2.0 and spans four sizes from on-device to workstation, so you can weigh deployment and fine-tuning options for open models.
