Can the Mac 16 GB run Boogu-Image (Turbo)?
Not at full quality. The 16-bit and 8-bit files are too big for the Mac 16 GB; the largest that fits is Q5_1 (8.6 GB).
Q5_1 (8.6 GB) fits with only 1.5 GB to spare (about 11.2 GB of 12.7 GB). Quality: close; small differences in fine detail. For better quality, Q8_0 (11.6 GB) also runs, with about 1.5 GB spilling into system RAM - a little slower, still practical.

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 25.4 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 9.4 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

“Needed” adds 1.8 GB of working memory for Boogu-Image and a 0.8 GB reserve. Sizes 2026-10-01. FP8 and INT8 files are left out on a Mac: Apple GPUs cannot compute FP8, so ComfyUI either fails to load them or converts them back to 16-bit, which saves no memory. Use a 16-bit or GGUF file.
03Measured and reported results
Nobody has sent measured numbers for this pair yet. If you run Boogu-Image on a Mac 16 GB, send your time per image and peak VRAM and it will appear here, credited.
04With more VRAM
With 16 GB you could run Boogu-Image at 8-bit or better (Q8_0, 11.6 GB) with no offloading: for example on the RTX 5080 16 GB, RTX 5070 Ti 16 GB, RTX 5060 Ti 16 GB.
05About 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 →

06Questions
How much VRAM does Boogu-Image need?
Around 10.0 GB with the smallest file (Q4_1) and 12.9 GB with an 8-bit file (FP8). The full 16-bit file needs about 23.2 GB.
Which Boogu-Image file should I download for the Mac 16 GB?
Q5_1 (8.6 GB) from realrebelai/Boogu-Image-Turbo_GGUFs. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
FP8 or Q8_0 for Boogu-Image on the Mac 16 GB?
Q8_0 (11.6 GB). The Mac 16 GB has no FP8 maths, so FP8 (10.3 GB) only saves memory and is a step further from the original.
How much do I need to download for Boogu-Image on the Mac 16 GB?
19.4 GB: boogu-turbo-dit-Q5_1.gguf, qwen3vl_8b_fp8_scaled.safetensors, flux1_vae_bf16.safetensors.
