Qwen Image 2.1 downloads: component sets, quantization and source identity
Select the diffusion model, conditioning encoder and VAE separately. Keep optional prompt enhancers and file-size estimates out of minimum-VRAM claims.
Select a complete set
The reviewed official template selects the three files below. These are model-folder locations, not packages to install with pip. Q05
ComfyUI/models/
diffusion_models/qwen_image_2.1_int8_convrot.safetensors
text_encoders/qwen3vl_8b_int8_convrot.safetensors
vae/qwen_image_2.1_vae_bf16.safetensors
Choose variants deliberately
The Comfy-Org card also lists a BF16 diffusion model and BF16 and W4A8 encoder variants. Q08 Treat the generator and conditioning encoder as separate selections. Match each selection to the loader and implementation you are using; a shared safetensors extension does not prove that a different quantization layout is supported. Keep the VAE in the set.
Do not substitute a prompt enhancer for the encoder
Files containing pe_t2i or pe_i2i are extra prompt-rewriting models. They do not replace qwen3vl_8b_*. The baseline graph does not become incomplete merely because an optional rewriter has not been downloaded. The publisher's pinned metadata provides SHA-256 values and exact byte counts for both enhancers at one repository commit; this site has not downloaded or hashed either file. Q14 Q15
Keep the source identity
Open the original file page and record the repository, relative path, revision, displayed size and license. The official template also links the Comfy-Org repository on ModelScope. That is an author-declared alternative entry point; this review has not checked file-by-file equality across the two hosts. Q05 Do not replace it with an unrelated mirror merely because the article is being read in Chinese.
Disk size is not a GPU budget
The W4A8 encoder page displays roughly 6.31 GB and the VAE page roughly 676 MB. Neither number measures the complete runtime. Q12 Q13 The publisher's pinned file metadata reports exact byte counts and LFS SHA-256 values for all eight listed files; these are source metadata, not local hash or GPU-memory measurements.
A filename can outlive its contents
The BF16 file history includes an old-file rename followed by an upload under the original name. Q16 Preserve revision and checksum information in addition to the filename. A checksum mismatch can mean that the upstream file changed, not only that a transfer failed. Compare identities before deleting a previously working copy. The eight inventory URLs now use an immutable repository commit; the model card and history views under main can change later.
