Gemma 3 4B IT
Google's 4B instruction-tuned Gemma 3 model with text and image-input capabilities in its published model family.
Model overview
Available quantizations
Lower-bit quantizations generally use less memory. The compatibility calculator uses these candidates and its transparent approximate memory assumptions; it does not make a performance guarantee.

Compatibility notes
Estimates use the cataloged model-weight size (or a parameter-based estimate), apply weight overhead, and include standard runtime overhead. Context/KV-cache estimates are shown separately only when a target context and supported sourced architecture metadata are available. Real requirements vary with runtime, drivers, and other system use. A model page cannot determine compatibility without your hardware profile; use the calculator for that assessment.
