Gemma 3 4B IT — Hardware Requirements & GPU Compatibility

Vision

Gemma 3 4B IT is a small, roughly 4.3-billion-parameter model from Google's earlier Gemma 3 generation, tuned for instruction-following and chat. It accepts image input alongside text, so it can handle visual question answering and image-grounded prompts in addition to text-only conversation. At this size, the model is comfortable on modest consumer hardware, running even on integrated graphics at low quantization, making it one of the most accessible vision-capable models for local use. Released on February 20, 2025, Gemma 3 4B IT predates the Gemma 4 family and is distributed under Google's Gemma license terms rather than a standard open-source license. Its compact size and image-input support make it a practical choice for lightweight, on-device multimodal applications.

Frequently Asked Questions

How much VRAM does Gemma 3 4B IT need?

Gemma 3 4B IT requires 2.8 GB of VRAM at Q4_K_M, or 9.5 GB at BF16.

VRAM = Weights + KV Cache + Overhead

Weights = 4.3B × 4.8 bits ÷ 8 = 2.6 GB

KV Cache + Overhead ≈ 0.2 GB (at 2K context + ~0.3 GB framework)

Fit ratings and hardware model lists check this model with room for a 16K-token context, which needs a little more memory.
