Google released Gemma 4 yesterday, and it's incredibly powerful! It's specifically designed to run on local devices (like phones and computers) and supports agents and tools. Four parameter sizes: E2B: Primarily for mobile phones/IoT/edge devices. E4B: Designed for mobile devices + Jetson/Raspberry Pi. 26B MoE: 3.8B per activation, very small effective parameters, focusing on high TPS and low latency. 31B Dense: Fully dense 31B, primarily for desktop workstations/single-card H100, etc. This time, they prioritized Agency Workflows support: native support for Function Calls, JSON and structured output, and System Instructions. Even stronger, it's a native multimodal model, supporting image and video understanding, speech-to-text, and can function as a local voice assistant. Furthermore, this time it's truly Apache 2.0 open source, allowing commercial use, redistribution, embedding in products, and private deployment without additional terms.
