Stable Diffusion 3.5 Large GGUF files and Mac RAM

8.1 billion parameter MM-DiT text-to-image model with three text encoders, positioned for professional use at 1 megapixel. The Stability AI Community License requires registration for commercial use and ends above USD $1,000,000 annual revenue.

No published Mac run with a GGUF build yet. The smallest complete GGUF download is 16.36 GB; a download that fits in memory does not prove the model runs.

Stability AI Community License. Commercial use: restricted. Excluded territories: none listed. Commercial use requires registration with Stability AI. Licenses terminate above USD $1,000,000 in annual revenue until a separate license is requested.

This is Stable Diffusion 3.5 Large, not Large Turbo or Medium.

Does it fit your Mac's RAM?

Published names the exact measured machine. est. is a memory calculation. unknown means the run verdict is not established, not that the model fails.

How does it rank in blind votes?

#81 of 82 in text to image blind votes, from 23,396 votes.

Quality: blind human votes from stable-diffusion-v35-large (arena.ai), CC BY 4.0, snapshot 2026-10-07. Scores are for the Arena checkpoint, not your local quantized build.

Which Mac software routes are listed?

  • ComfyUI

    Official

    Formats: safetensors, gguf. Memory policy: component stages stay resident.

    On Apple Silicon ComfyUI runs on PyTorch MPS, not MLX. GGUF files need the separate city96/ComfyUI-GGUF custom node. Resident size is the sum of the weights, an upper bound: ComfyUI can unload models between stages and publishes no per-model Mac peak.

What does the official configuration say?

"The launch page says the model suits professional use at 1 megapixel resolution. It gives no Large-specific RAM or VRAM minimum."

What known issues should you check?

  • Known issue 1

    One reported ComfyUI run of SD 3.5 Large on a 16 GB Mac mini M4 failed with an MPS memory error. This is one issue report, not a general 16 GB verdict.
