Answer

3 of 9 listed image models run on a 16 GB Mac: Qwen-Image-2.1, FLUX.2 [klein] and SDXL Base 1.0. Highest blind-vote rank among them: Qwen-Image-2.1, #19 of 82 in text to image (Arena, snapshot 2026-10-07). No figure covers FLUX 3 Image Klein, MOSS-Image and Z-Image-Turbo at this size yet. FLUX.2 [dev], Krea 2 Turbo and Stable Diffusion 3.5 Large need more memory.

License check before commercial use: Qwen-Image-2.1, FLUX.2 [klein].

Table 1

Which image models run on a 16 GB Mac?

9 models

Runs means a published run on 16 GB or less, or a model card or app maker figure at or below it. Does not fit means the weights the app keeps resident in the smallest complete build are larger than 16 GB. A Mac has one memory pool, so the text encoder cannot move out to a separate system RAM; an app that loads the text encoder and the main model one after the other counts only its largest stage. unknown means no source covers this size yet; it is not a failure.
