About Gemma 4 E4B

Gemma 4 E4B is a multimodal model with 4.5 billion effective parameters (8B with embeddings). It supports text, image, video, and audio inputs with a 128K token context window and over 140 languages.

Gemma 4 introduces Per-Layer Embeddings (PLE) for richer token representations, shared KV cache for efficient long-context inference, and variable aspect ratio vision encoding. It offers a strong balance of capability and efficiency for multimodal tasks.
