Gemma 4 E2B

Gemma 4 E2B is an ultra-efficient model with 2.3B effective parameters (5.1B with Per-Layer Embeddings) designed for mobile and IoT devices. Supports text, image, and audio input with 128K context window, delivering frontier capabilities on edge devices with near-zero latency and offline operation. Features built-in reasoning mode and native function calling for agentic workflows.

About Gemma 4

Gemma 4 is Google DeepMind's most advanced open model family, built from Gemini 3 research and technology. Featuring both Dense and Mixture-of-Experts (MoE) architectures, these multimodal models handle text, images, and audio (on smaller variants), with context windows up to 256K tokens. Designed for frontier-level performance across reasoning, coding, and agentic workflows, Gemma 4 delivers unprecedented intelligence-per-parameter from mobile devices to enterprise servers. Released under Apache 2.0 license.
