+# Prompting Prism / Qwen Image 2.1
+
+Start with a concrete natural-language paragraph: medium, subject, action,
+relationships, composition, lighting, materials, then exact lettering. Keep each
+attribute next to the object it describes. The supplied workflows use 40 steps,
+Euler/simple, CFG 1, denoise 1, and fixed seeds.
+
+## Text to image
+
+Describe a scene that can be depicted in one image. For a product photo, specify
+the object, material, label, supporting objects, surface, background and lighting.
+For a portrait, specify the action and framing as well as the person's appearance.
+The included product prompt is a complete starting point.
+
+Set output width and height in Empty Latent Image. The encoder's resolution field
+controls reference-image resizing, not the independent text-to-image canvas.
+Changing image dimensions may change composition even with the same seed.
+
+At CFG 1, the negative conditioning branch does not guide sampling. Put essential
+requirements in the positive prompt. Higher CFG is not a validated improvement
+for this package.
+
+## Lettering
+
+Quote the exact text and specify its position and hierarchy. Example:
+
+> Large cream headline at the top reads exactly "TAKE THE SCENIC ROUTE".
+> A smaller line at the bottom reads exactly "SLOW TRAVEL CLUB".
+> Generous margins, flat navy, coral and cream inks, subtle paper grain.
+
+Proofread the result. Clear headings and short labels worked in the release
+examples, but the astronaut test also shows small-label spelling errors in the
+BF16 baseline. Neither precision is a guarantee of perfect text.
+
+## Image editing
+
+Upload the reference in Load Image. Connect it and the matching VAE to
+TextEncodeQwenImage21. Use that node's latent output for sampling, so the output
+matches the processed first reference's size. The included editing workflow
+already has those connections.
+
+Name the changes and the elements to preserve:
+
+> Change the amber glass bottle to deep translucent cobalt-blue glass and the
+> brass cap to brushed silver. Replace the orange with lime and rosemary with
+> lavender. Keep the bottle shape, cream EMBER label, marble pedestal, camera
+> angle, background and lighting.
+
+For multiple references, refer explicitly to the first and second images.
+Reference preservation is semantic, not pixel-locked: small details, hand poses,
+clothing coverage and object placement can change.
+
+## Native transparency
+
+Use an explicit RGBA instruction around the subject description:
+
+> This is an RGBA image with transparency. A charming hand-painted gouache sticker
+> of a small orange fox curled around a glowing blue book, round spectacles,
+> moss-green scarf, clean complete silhouette and generous empty margin.
+> The image has alpha channel and the background is transparent.
+
+Save as PNG. Check the alpha channel or composite over a checkerboard. The hidden
+RGB under transparent pixels can be colored; an RGB-only viewer is not an alpha
+test. The supplied example has alpha values spanning 0 through 255.
+
+## Comparisons
+
+Keep the prompt, seed, dimensions, sampler, steps, backend and encoder mode fixed.
+The optional NVFP4 encoder patch changes conditioning arithmetic and may change
+the generated image. Compare stock and accelerated modes as distinct settings.
+The gallery contains the complete 12-prompt, two-seed comparison set.

+# 🚀 Prism Image 2.1 — NVFP4 for ComfyUI
+
+**The image model AND the text encoder. 12.42 GB for the complete package.**
+
+I converted Qwen Image 2.1's image transformer and Qwen3-VL 8B language encoder
+directly from the official BF16 weights into native ComfyUI NVFP4. The vision
+tower, embeddings, output head, critical image-model tensors, and VAE stay BF16.
+Real Blackwell FP4 kernels in both denoising and text conditioning, with an
+included small runtime patch for the latter. No new nodes.
+
+**Built with Qwen.** Research/evaluation use only under the included license.
+
+**RTX 5090: 6.746 s median for a complete 1024×1024, 40-step run** versus
+15.629 s with BF16 and 7.553 s with official INT8. Three warm runs per variant,
+every node executed, including text encoding. This one-prompt benchmark used the
+encoder patch; [full method and limits](VALIDATION.md).
+
+![Reference photo and the NVFP4 product edit](assets/editing.jpg)
+
+## 📦 Download once, wire nothing
+
+Tested with **ComfyUI 0.36.0**, PyTorch **2.14.0+cu130**, comfy-kitchen **0.2.35**,
+and an **RTX 5090**. Use a ComfyUI build with `TextEncodeQwenImage21` and native
+NVFP4 support. Older builds without the Qwen Image 2.1 integration will not work.
+
+| File | Where it goes | Size |
+|---|---|---:|
+| [prism_image_2.1_nvfp4.safetensors](diffusion_models/prism_image_2.1_nvfp4.safetensors) | `ComfyUI/models/diffusion_models/` | 4.20 GB |

+| [qwen_image_2.1_vae_bf16.safetensors](vae/qwen_image_2.1_vae_bf16.safetensors) | `ComfyUI/models/vae/` | 0.68 GB |
+
+The original BF16 set is 32.44 GB. This package is **61.7% smaller on disk**.
+File sizes are decimal GB, not a VRAM requirement. Keep your existing identical
+VAE if you already have it.
+
+1. Put the three files in the folders above and refresh ComfyUI's model list.
+2. For accelerated NVFP4 text conditioning, apply the [runtime patch](runtime/README.md)
+   and restart. Without it, the same models and nodes work, but text conditioning
+   uses dequantized weights and FP32 activations. Denoising still uses NVFP4.
+3. Import one of the workflows below using **Ctrl+O**, then click **Run**.
+4. For editing, use **Upload** in Load Image to select the included
+   [reference image](input/prism_edit_reference.png), or your own image.
+
+| Working workflow | Purpose |
+|---|---|
+| [01 — Text to image](workflows/01_Text_to_Image.json) | 1024×1024 product example; change the prompt and latent size |
+| [02 — Image editing](workflows/02_Image_Editing.json) | One reference, coherent material/color/object changes |
+| [03 — Transparent RGBA](workflows/03_Transparent_RGBA.json) | Native alpha output; no background-removal node |
+| [04 — 2K typography](workflows/04_2K_Typography.json) | 2048×2048 poster with exact requested lettering |
+
+The workflows use core `UNETLoader`, `CLIPLoader` (type **qwen_image**),
+`TextEncodeQwenImage21`, `KSampler`, and VAE nodes. Leave diffusion weight dtype
+at **default**. Defaults are 40 steps, Euler, simple scheduler, CFG 1, denoise 1.
+The encoder node's resolution controls reference resizing; text-to-image output
+size comes from Empty Latent Image. API equivalents are in [workflows/api](workflows/api).

+All **24 matched pairs** are in [COMPARISONS.md](COMPARISONS.md). Download
+`gallery.html` and its `assets` folder together for the offline comparison slider.
+See [PROMPTING.md](PROMPTING.md) for text, editing, lettering and transparency tips.
+
+See [VALIDATION.md](VALIDATION.md) for the test set, measured results, precision
+tradeoffs, and execution requirements. The comparisons use BF16 source weights
+against this complete accelerated NVFP4 package. Quantization changes results;
+this is not a promise of pixel-identical output or a universal quality ranking.
+
+## 🧠 What's actually quantized?
+
+| Component | Policy |
+|---|---|
+| Image transformer | 192 attention Q/K/V/output and fused MLP gate/up/output matrices: NVFP4 |
+| Qwen3-VL language backbone | 252 attention and MLP matrices: NVFP4 |
+| Vision tower, token embeddings, language head | Original BF16 tensors retained |
+| Image-model input/output, timestep, modulation, normalization | Original BF16 tensors retained |
+| VAE | Original BF16 file, unchanged |
+| Scales | E4M3 FP8 blocks of 16, FP32 tensor scales |
+
+Native packed E2M1 FP4, native scale layout, and per-layer `comfy_quant` metadata.
+This is a mixed-precision NVFP4 stack, not every parameter forced into four bits.
+No GGUF loader, no requantization of the INT8 release, no dropped vision tower.
+No calibration or fine-tuning was used for this conversion.
+
+## 🔧 Reproduce it
+
+Source repository: [Comfy-Org/Qwen-Image-2.1](https://huggingface.co/Comfy-Org/Qwen-Image-2.1),
+revision `ace0edeb3791a594ddfa36ed5f41a178a394e921`.
+
+Use the Python environment of the tested ComfyUI installation:
+
+```powershell
+python tools/convert.py path/to/qwen_image_2.1_bf16.safetensors diffusion_models/prism_image_2.1_nvfp4.safetensors --component dit --comfy-root path/to/ComfyUI
+python tools/convert.py path/to/qwen3vl_8b_bf16.safetensors text_encoders/prism_qwen3vl_8b_nvfp4.safetensors --component encoder --comfy-root path/to/ComfyUI
+```
+
+The converter uses installed Comfy Kitchen operations, validates matrix alignment,
+and emits tensor manifests with source/output hashes and reconstruction error.
+`tools/verify.py SOURCE CONVERTED` checks the stored format, checkpoint hash, and
+exact equality of every protected tensor. Final file checksums are in `SHA256SUMS`.

+# Validation — RTX 5090, 20 September 2026
+
+## What passed
+
+- Both native safetensors checkpoints loaded through standard ComfyUI loaders.
+- 48 main renders: 12 prompts × two seeds × BF16/NVFP4, all at 1024×1024.
+- Eight extended renders: product edit, portrait edit, transparent RGBA and 2K
+  typography, each with BF16 and NVFP4.
+- Six held-out renders: Chinese lettering, 1536×864 landscape and two-reference
+  image editing, each with BF16 and NVFP4. These prompts were not used to choose
+  the conversion recipe.
+- Four shipped workflows imported and executed through the actual frontend.
+- Three subjects tested across all four combinations of BF16/NVFP4 transformer
+  and encoder weights, using the original stock conditioning path.
+- Real SM120 block-scaled FP4 CUDA kernels observed in both language conditioning
+  and image denoising with the accelerated encoder patch.
+- All 571 protected tensors checked for exact equality against the source files.
+  All 444 quantized matrices checked for packed shape, marker, scale dtype and
+  finite scales. Source and release file hashes recorded.
+- Hub-uploaded weights downloaded into a separate directory and matched against
+  the release SHA-256 hashes. The VAE hash matches the official original.
+- All four API workflows also passed using the Hub-downloaded files on the
+  unpatched base runtime, with custom nodes disabled. Thus stock compatibility
+  and optional accelerated conditioning were tested separately.
+
+No calibration, optimization against the test prompts, or fine-tuning was used.
+The quantization recipe remained unchanged after its first conversion.
+
+## Measured performance
+
+1024×1024 EMBER product prompt from the shipped generation workflow, seed
+20260922, 40 steps, Euler/simple, CFG 1, denoise 1. One first-after-unload run,
+then three warm runs per variant. **Every node executed on every repeat** using
+`--cache-none`; the histories were checked for an empty cached-node list.
+Elapsed time comes from server execution-start/success timestamps, not polling
+latency. Includes conditioning, denoising, VAE decode and PNG save.
+
+| Weights / encoder mode | Warm median | Warm range | First after unload | Largest sampled GPU use, warm |
+|---|---:|---:|---:|---:|
+| Official BF16 / stock FP32 conditioning | 15.629 s | 15.553–15.650 s | 18.932 s | 31,677 MiB |
+| Official INT8 ConvRot / stock conditioning | 7.553 s | 7.496–7.591 s | 9.973 s | 18,433 MiB |
+| Prism NVFP4 / patched BF16 + NVFP4 conditioning | **6.746 s** | **6.706–6.749 s** | **8.083 s** | **13,249 MiB** |
+
+This NVFP4 workflow delivered **2.32× the BF16 throughput** and took **10.7% less
+time than INT8** in this one controlled test. These are local measurements, not
+general speed guarantees. First-after-unload is not a cold filesystem-cache or
+fresh-boot test. The quality-suite runs used ordinary node caching and are not
+the basis of this performance table.
+
+GPU memory was sampled through `nvidia-smi` every 100 ms. Values are **whole-GPU
+usage**, including Windows and other idle desktop services, not PyTorch peak
+allocated memory or a minimum VRAM requirement. The largest sampled NVFP4 warm
+value is about 12.94 GiB. No other model inference job was running during this
+benchmark. Hardware other than the RTX 5090 was not benchmarked.
+
+Raw measurements: [benchmark.json](validation/benchmark.json).
+
+## Quality observations and limits
+
+The main set covers portraits, landscapes, glass products, typography, object
+counts and spatial relationships, illustration, fashion, night scenes,
+architecture, macro, astronaut portraits and botanical posters. All 24 matched
+pairs are published in [COMPARISONS.md](COMPARISONS.md).
+
+Visual review found coherent images and preserved useful text, material and
+editing capabilities. It also found real differences: changed portrait details,
+object placement, typography layout and small material/color details. In one
+macro pair the quantized spider is less green. Small astronaut-label spelling
+was imperfect in the BF16 baseline too. The Chinese probe retained the requested
+wording, but NVFP4 moved the subtitle above the cup rather than below it.
+
+The two-reference test combined the reference woman with the EMBER bottle and
+removed the violin, while changing hand pose. The product edit preserved the
+label and scene while changing glass, metal and props. Portrait recoloring can
+also change sleeve coverage. This is semantic reference preservation, not a
+pixel-locked edit.
+
+The transparent example has genuine RGBA output: alpha minimum 0, maximum 255,
+49.3% of pixels below alpha 16 and 49.7% above alpha 240. See the original
+[RGBA PNG](assets/03_Transparent_RGBA.png) and the
+[checkerboard composite](assets/transparency-checker.jpg). RGB-only viewers may
+show the purple RGB values stored underneath transparent pixels.
+
+This is a small local evaluation, not a blinded preference study or a benchmark
+proving no quality loss. There was no LoRA, ControlNet, training or video test.
+Long text, exhaustive multilingual coverage and every reference-image count were
+not tested. Stock encoder arithmetic and accelerated encoder arithmetic can
+produce different images even with identical weights and seeds.
+
+## Runtime and kernel evidence
+
+- Windows, Python 3.13.12, RTX 5090 32 GB.
+- ComfyUI 0.36.0, base commit `99073836d45f66053c45ba8564984e6def9cebba`.
+- Included Qwen-specific encoder patch; local validation commit `2d324220`.
+- PyTorch `2.14.0+cu130`; comfy-kitchen `0.2.35`; comfy-aimdo `0.5.5`.
+- Frontend package `1.53.6`; safetensors `0.8.0`.
+- Comfy Kitchen attention, normal VRAM mode, async offload, batch size one.
+- All tests ran with `--disable-all-custom-nodes`.
+
+The profiler captured kernels beginning
+`cutlass3x_sm120_bstensorop_s16864gemm_block_scaled_ue4m3xe2m1_ue4m3xe2m1`
+for short conditioning sequences and image-denoising sequences. This confirms
+hardware FP4 execution, rather than relying on checkpoint names or successful
+loading. Raw observations: [kernel_audit.jsonl](validation/kernel_audit.jsonl).
+No NVFP4 matmul-fallback warning occurred in the successful audited runs.
+
+The first acceleration probe exposed FP32 activations entering a BF16/FP16-only
+quantizer. The included patch fixes that at the Qwen Image 2.1 encoding boundary:
+vision preprocessing stays unchanged, the resulting multimodal embeddings become
+BF16 only for NVFP4 conditioning on supported hardware, and existing ComfyUI
+matmul dispatch is used. BF16 and INT8 checkpoints retain their original path.
+
+## Precision and provenance
+
+The DiT converts 192 matrices and retains its other 73 tensors. The encoder
+converts 252 matrices and retains its other 498 tensors, including the complete
+vision tower, embeddings and output head. Per-matrix relative reconstruction
+RMSE is recorded in the manifests; it is not an image-quality score.
+
+Source revision: `Comfy-Org/Qwen-Image-2.1@ace0edeb3791a594ddfa36ed5f41a178a394e921`.
+The image transformer source SHA-256 is
+`89f4158d066cc33906a199fca85634f766892dd78f49b6698dabf187ac86c4bc`.
+The encoder source SHA-256 is
+`68bdc82bc1b66851162ae656225e7e2068166b603db19bd5d5a3b90eb12669a9`.
+Full tensor manifests sit beside each checkpoint; `SHA256SUMS` covers the release.
