Gemma 3 1B IT
Google's compact instruction-tuned Gemma 3 model for constrained local systems.
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.
Google Gemma 3 model card; verified value, last verified 2026-09-23. The publisher specifies text and image input and 32K context for the 1B variant; the 128K figure applies to larger Gemma 3 variants. The current catalog does not verify whether its generic GGUF planning candidates include the vision components. View source
Multimodal memory scope: The catalog has not verified whether the selected GGUF weights include all multimodal components or require separate files. Multimodal runtime memory is not estimated and may be missing from this result. Google Gemma 3 1B model card
