Can the Mac 16 GB run ERNIE-Image (Turbo)?
Yes, but only just: Q8_0 leaves 1.7 GB free on the Mac 16 GB.
Q8_0 (8.7 GB) fits with only 1.7 GB to spare (about 11.0 GB of 12.7 GB).

Only for some workflows: ERNIE prompt enhancer (optional) (6.9 GB). On a Mac, FP8 text encoders do not load, so a 16-bit one is listed. Sizes from Hugging Face, 2026-10-01.
Shared memory: about 22.7 GB of your 16 GB. On this machine the model, the text encoder, the VAE and the operating system all use the same memory. That is about 6.7 GB more than there is. It still runs: while the model works, the system compresses or swaps the idle text encoder, so loading and changing the prompt get slower. A smaller file or text encoder avoids that. calculated

04About the Mac 16 GB
A Mac with 16 GB shares that memory between the CPU and the GPU. On current macOS the GPU may use about 12.7 GB of it by default (older macOS versions: about 11.5 GB); that is the figure used here. ComfyUI can go past it, but macOS then starts compressing and swapping memory and everything slows down. ComfyUI runs on Apple GPUs through PyTorch's MPS backend. 16-bit and GGUF files work; FP8 and INT8 files do not save memory on a Mac, so they are skipped. Speed is the catch: even the fastest Macs are several times slower per image than a desktop RTX card. Chips sold with 16 GB: M1, M1 Pro, M2, M2 Pro, M3, M4, M5, M6 (memory bandwidth 68.25–200 GB/s - the higher, the faster). Everything about Macs and local AI →

05Questions
How much VRAM does ERNIE-Image need?
Around 5.5 GB with the smallest file (Q2_K) and 11.0 GB with an 8-bit file (Q8_0). The full 16-bit file needs about 18.4 GB.
Which ERNIE-Image file should I download for the Mac 16 GB?
Q8_0 (8.7 GB) from unsloth/ERNIE-Image-Turbo-GGUF. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
How much do I need to download for ERNIE-Image on the Mac 16 GB?
16.7 GB: ernie-image-turbo-Q8_0.gguf, ministral-3-3b.safetensors, flux2-vae.safetensors.
