Frequently asked questions
FAQ — AuraFlow v0.3 VRAM, Runtimes & Fit
How much VRAM does AuraFlow v0.3 need?
AuraFlow v0.3 (6.35B parameters) requires approximately 17.0 GB of VRAM at FP16 precision for standard 1024×1024 image generation. If you want a lighter setup, lower precisions like FP8 can reduce memory use when available.
Can I run AuraFlow v0.3 on an 8GB GPU?
AuraFlow v0.3 usually needs more than 8GB for comfortable local use. Check the VRAM table above for the exact resolution and precision trade-off.
Does AuraFlow v0.3 work in ComfyUI and Diffusers?
AuraFlow v0.3 is marked for ComfyUI and Diffusers support in our catalog, so those are the runtimes we recommend first for local setup. If your workflow uses another front end, check the model's available formats and workflow notes above before downloading.
Can I run AuraFlow v0.3 on RTX 4090?
Yes, the RTX 4090 (24 GB VRAM) can run AuraFlow v0.3 comfortably at FP16. Expected generation time is around ~18s per image at 1024×1024.
Does AuraFlow v0.3 support ControlNet?
There are currently no known ControlNet adapters for AuraFlow v0.3. Check Hugging Face and Civitai for community-contributed adapters.
Does AuraFlow v0.3 have LoRA support?
No LoRA ecosystem. AuraFlow is relatively niche compared to Flux and SDXL. The LoRA ecosystem for AuraFlow v0.3 is rated as "none". Each LoRA adds roughly 0.0 GB of extra VRAM.
How fast is AuraFlow v0.3?
On a reference GPU (RTX 4090 24GB), AuraFlow v0.3 generates a 1024×1024 image in approximately ~18s at FP16 with 28 inference steps. Faster GPUs with higher memory bandwidth will produce images more quickly.
