Install ComfyUI
Download ComfyUI for Windows and select the NVIDIA/CUDA setup. Open ComfyUI before adding any model files.
Official ComfyUI download Qwen-Image-2.1 official ComfyUI guideCreate an image with the official Qwen Image 2.1 ComfyUI template, or choose the publisher Turbo pipeline for a faster eight-step route.
These are capacity starting points for the complete pipeline, not speed tests. The ComfyUI Base route and publisher Turbo route use different files and runtimes.
| Machine | Qwen-Image-2.1 · 7B Base | Qwen-Image-2.1 Turbo · 7B |
|---|---|---|
| NVIDIA GPU · 16 GB VRAM | Possible with ComfyUI offload; start at 1024 px and check memory. | Check complete BF16 pipeline fit; a small package size alone is insufficient. |
| NVIDIA GPU · 24 GB VRAM | Good starting candidate at 1024 px; verify actual peak. | Candidate; verify CUDA memory and leave headroom for encoders. |
| NVIDIA GPU · 32 GB VRAM | Good starting candidate; 2K output costs more memory. | Good capacity candidate; benchmark the exact output size. |
| AMD Radeon · 24 GB VRAM | Conditional on supported ComfyUI ROCm setup; check all nodes. | No documented Turbo ROCm route here; use NVIDIA rental. |
| Intel Arc · 16 GB VRAM | No validated Qwen 2.1 pipeline in this guide; use NVIDIA rental. | No validated Turbo Intel route; use NVIDIA rental. |
| Apple Silicon · 64 GB unified memory | ComfyUI Mac route available; start at 1024 px and check pressure. | No validated Turbo MPS route; choose Base or NVIDIA rental. |
| CPU only · 64 GB RAM | Not a practical first-run path for this guide; rent a GPU. | No CPU route documented here; rent a GPU. |
| RunPod · NVIDIA GPU · 48 GB VRAM | Generous memory candidate; check storage and ComfyUI nodes. | Generous candidate for BF16; verify runtime before a long rental. |
Start small, then raise resolution after a successful render. Source documentation verifies package files and settings; these rows are estimates, not YouRunAI benchmarks.
Choose the maintained ComfyUI template for Base or the publisher’s faster Turbo checkpoint. The package selector changes every step.
Select the weights you want. The instructions, downloads and settings change with your choice.
Save your machine in My Hardware to get an automatic starting choice. You can always choose any package yourself.
Begin at 1024 px and 25 steps. A 64 GB Apple Silicon Mac is an estimated starting point for the complete ComfyUI pipeline, not a measured speed result. Increasing resolution and image references raises full-pipeline memory.
Choose your computer first, then its GPU path. Follow the visual setup and import the linked workflow.

Official ComfyUI download Qwen-Image-2.1 official ComfyUI guideDownload the diffusion checkpoint, base text encoder, and VAE into these ComfyUI/models folders. The prompt-enhancement encoder is optional while refine_prompt is off. Restart ComfyUI after placing files.
In ComfyUI Workflow Templates, choose Qwen-Image-2.1 Text to Image, or import this JSON. Confirm each loader names the files above; update ComfyUI if a node is red.
Download the official ComfyUI JSON Read the Qwen Image setup and settingsIn the Qwen Image 2.1 Text to Image subgraph, select the exact loaded model, enter a scene prompt, start at 1.0 megapixel (about 1024×1024), 25 steps, CFG 1, Euler/simple, and record the seed. Leave prompt enhancement off for the first run.
Click Queue. Open the generated PNG in ComfyUI/output and compare it to the prompt. Save the seed and size alongside the image so a second run can be reproduced.
Open the PNG in ComfyUI/output or the Turbo script folder. Confirm it follows the prompt and record the package, seed, resolution and settings.
The base and Turbo packages are distinct checkpoints. The ComfyUI template loads a Comfy-Org repackaging of the Qwen publisher weights. Turbo uses Qwen’s own Diffusers example. GPU advice is estimated from full-pipeline components, not a site-run benchmark.
Update ComfyUI and compare the three required filenames and their folders with the official Qwen guide. Restart after adding files; keep prompt enhancement off until its optional encoder is installed.
Check the actual input pixel count and start near 1024×1024, close other GPU apps, and use the int8 ComfyUI template. Turbo needs its separate BF16 pipeline and sufficient GPU memory.
Install Diffusers from current source as the Qwen Turbo card requires for saved sampling sigmas; confirm the selected model ID is Qwen/Qwen-Image-2.1-Turbo, not Base.

Source-backed package and platform-route plan for private local chat with Qwen3.5 · 9B. Preserves the official Ollama 9B package, a smaller 4B family fallback, and a clearly labeled community uncensored GGUF option.
Run Qwen3.8 27B with Ollama, connect it to Cline in VS Code, and make one reviewable code change in a tiny local project.
Generate images from text prompts in ComfyUI with the fast distilled or more adjustable base 4B model. Save your results and reuse the visual workflow.
