Frequently asked questions
How much VRAM do you need to run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF?
You need about 9.41 GB of VRAM to run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF entirely on the GPU using the IQ1_S quantization (at a 4,096-token context). Smaller quantizations lower the requirement at the cost of quality.
Can I run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF on an 8 GB GPU?
Partially. unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF only fits on an 8 GB GPU by offloading part of it to system RAM (with Q5_K_XL), which runs but is slower.
Can I run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF on a 16 GB GPU?
Yes. With 16 GB of VRAM you can run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF fully on the GPU using Q3_K_M (about 14.69 GB).
Can I run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF on a 24 GB GPU?
Yes. With 24 GB of VRAM you can run unsloth/Qwen3-30B-A3B-Instruct-2507-GGUF fully on the GPU using Q5_K_XL (about 21.23 GB).
What is the best quantization for unsloth/Qwen3-30B-A3B-Instruct-2507-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.
