gemma-3-270m-it GGUF size and VRAM requirements
unsloth/gemma-3-270m-it-GGUF is a compact instruction-tuned chat model with 0.27 billion parameters, built on the gemma3 architecture. It is released under the gemma license and has been downloaded 100,960 times.
To run unsloth/gemma-3-270m-it-GGUF locally at a 4,096-token context, its quantized versions need between 1.01 GB (IQ2_XXS, lowest quality) and 1.35 GB (F16, highest quality) of memory, weights plus KV cache and a system margin included.
For most users the best balance is F16, needing about 1.35 GB. That means unsloth/gemma-3-270m-it-GGUF fits entirely in the VRAM of a 6 GB GPU or larger, running fully on the GPU.

Frequently asked questions
How much VRAM do you need to run unsloth/gemma-3-270m-it-GGUF?
You need about 1.35 GB of VRAM to run unsloth/gemma-3-270m-it-GGUF entirely on the GPU using the F16 quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run unsloth/gemma-3-270m-it-GGUF on an 8 GB GPU?
Yes. With 8 GB of VRAM you can run unsloth/gemma-3-270m-it-GGUF fully on the GPU using F16 (about 1.35 GB).
Can I run unsloth/gemma-3-270m-it-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run unsloth/gemma-3-270m-it-GGUF fully on the GPU using F16 (about 1.35 GB).
Can I run unsloth/gemma-3-270m-it-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run unsloth/gemma-3-270m-it-GGUF fully on the GPU using F16 (about 1.35 GB).
What is the best quantization for unsloth/gemma-3-270m-it-GGUF?
If memory allows, higher bits-per-weight means better quality. A common sweet spot is a Q4_K_M or Q5_K_M quantization, which keeps most of the quality while roughly halving the memory versus 8-bit. Pick the highest quantization that still fits in your VRAM.
