It is designed for highly constrained on-device deployment with text, image, and audio input support. ## At a Glance **Where Gemma 3n E2B leads** - Smallest Gemma 3n model — lowest inference cost - Multimodal: text, image, and audio inputs at 2B effective param scale - MatFormer nested architecture for efficient on-device execution - Suitable for most-constrained mobile hardware **Where it lags** - 40.5% MMLU-Pro — limited academic knowledge at 2B scale - Below Gemma 3n E4B on all benchmarks (expected at 2B vs 4B) - Text-only alternatives (Llama 3.2 1B) offer similar size **Best for:** Most-constrained on-device deployment; wearables and IoT; minimum-footprint multimodal AI. ## What Gemma 3n E2B Is Gemma 3n E2B is the smallest model in Google's Gemma 3n family, announced at Google I/O 2025. At 2B effective parameters with the MatFormer nested architecture, it targets the most resource-constrained on-device use cases — wearables, IoT, and entry-level smartphones. Like Gemma 3n E4B, it supports text, image, and audio inputs — multimodal capability at scales where most models are text-only. The MatFormer architecture allows dynamic compute allocation, so actual inference cost varies by task complexity. For most mobile applications, Gemma 3n E4B provides meaningfully better benchmarks (50.6% vs 40.5% MMLU-Pro) with acceptable additional compute. E2B is preferred when E4B exceeds device constraints. ## Specifications | Field | Value | |---|---| | Organization | Google | | Effective parameters | 2B (MatFormer nested) | | License | Gemma Terms of Use | | HuggingFace | [google/gemma-3n-E2B-it](https://huggingface.co/google/gemma-3n-E2B-it) | | Release date | May 20, 2025 | | Knowledge cutoff | February 2025 | | Modality | Text + Vision + Audio | | Architecture | MatFormer (nested) | ## Pricing Open weights under Gemma Terms of Use — free to self-host.

What is Gemma 3n E2B?

Google's May 2025 smallest on-device multimodal model with 2B effective parameters (MatFormer), scoring 51.7% ARC-C, 40.5% MMLU-Pro, and 72.2% HellaSwag. Supports text, image, and audio.

Should I use Gemma 3n E2B or E4B?

E4B for better performance (50.6% vs 40.5% MMLU-Pro). Use E2B only when E4B exceeds device hardware constraints.
