Can the RTX 4060 Ti 16 GB run Qwen-Image-Edit (2511)?
Download Q3_K_M (9.9 GB). With the model's working memory it needs about 12.9 GB, leaving 3.1 GB spare on 16 GB. Quality: noticeable loss of detail. For better quality, Q4_K_M (13.2 GB) also runs, with about 0.2 GB spilling into system RAM — a little slower, still practical.
Worth trying on this GPU: with an up-to-date ComfyUI, Dynamic VRAM (on by default for NVIDIA since March 2026) streams whatever does not fit from system RAM, and ComfyUI's own start-up message recommends native FP8/INT8 files over GGUF, saying they “will be faster even if they are larger than your memory”. So before settling for a heavily compressed GGUF, try the native FP8 file (20.5 GB). The file recommended above is the best one that fits entirely — the safe choice on older ComfyUI versions, AMD and Intel. Comfy blog: Dynamic VRAM →

Alternatives: Qwen2.5-VL 7B BF16 (16.6 GB). The 16-bit text encoder is a little more faithful; the smaller one is chosen here because it loads faster and needs less RAM. Sizes read from Hugging Face (2026-09-25). “Download” links start the file directly; the file name links are the same files the official ComfyUI workflows use.
System RAM: 32 GB or more. ComfyUI keeps the model file, the text encoder and the VAE in system RAM and moves them to the GPU as needed. With this set of files that is about 19.6 GB, plus roughly 6 GB for Windows, ComfyUI and a browser: 25.6 GB in total. With less RAM it still runs, but Windows starts swapping to disk and loading gets very slow. calculated

03The text encoder
Qwen2.5-VL 7B: 16.6 GB as 16-bit, 9.4 GB as FP8. ComfyUI encodes the prompt first and can push the encoder out of VRAM before sampling, so it does not have to fit together with the model. On 16 GB the FP8 encoder fits on its own, so prompt encoding stays fast.
04About this GPU
The RTX 4060 Ti 16 GB is an Ada Lovelace GPU with hardware FP8, so ComfyUI can compute Comfy-Org's FP8 files natively: small and fast. (Plain FP8 files use FP8 maths with the --fast fp8_matrix_mult option.)

05What more VRAM would change
With 24 GB you could run Qwen-Image-Edit at 8-bit or better (FP8, 20.5 GB) with no offloading: for example on the RTX 4090 24 GB, RTX 3090 24 GB, RX 7900 XTX 24 GB.

07Questions
How much VRAM does Qwen-Image-Edit need?
Around 10.5 GB with the smallest file (Q2_K) and 23.5 GB with an 8-bit file (FP8), counting working memory and a small system reserve. The full 16-bit file needs about 43.9 GB.
Which Qwen-Image-Edit file should I download for the RTX 4060 Ti 16 GB?
Q3_K_M (9.9 GB) from unsloth/Qwen-Image-Edit-2511-GGUF. Load it with Unet Loader (GGUF) from the ComfyUI-GGUF node pack.
Is FP8 faster than GGUF on the RTX 4060 Ti 16 GB?
It can be. This GPU has FP8 hardware, and ComfyUI computes FP8 natively for files made for it (Comfy-Org's fp8_scaled files), or for any FP8 file with the --fast fp8_matrix_mult option. GGUF files are unpacked on the fly, which costs some speed.
How much do I need to download for Qwen-Image-Edit on the RTX 4060 Ti 16 GB?
About 19.6 GB for the model file, text encoder and VAE listed on this page, and the same again free on disk. With a 16 GB card, 32 GB of system RAM or more is recommended.
