 ## 🔥 Latest Updates
+### July 15 2025: WanGP v7.0 is an AI Powered Photoshop
+This release turns the Wan models into Image Generators. This goes way more than allowing to generate a video made of single frame :
+- Multiple Images generated at the same time so that you can choose the one you like best.It is Highly VRAM optimized so that you can generate for instance 4 720p Images at the same time with less than 10 GB
+- With the *image2image* the original text2video WanGP becomes an image upsampler / restorer
+- *Vace image2image* comes out of the box with image outpainting, person / object replacement, ...
+- You can use in one click a newly Image generated as Start Image or Reference Image for a Video generation
+
+And to complete the full suite of AI Image Generators, Ladies and Gentlemen please welcome for the first time in WanGP : **Flux Kontext**.\
+As a reminder Flux Kontext is an image editor : give it an image and a prompt and it will do the change for you.\
+This highly optimized version of Flux Kontext will make you feel that you have been cheated all this time as WanGP Flux Kontext requires only 8 GB of VRAM to generate 4 images at the same time with no need for quantization.
+
+WanGP v7 comes with *Image2image* vanilla and *Vace FusinoniX*. However you can build your own finetune where you will combine a text2video or Vace model with any combination of Loras.
+
+Also in the news:
+- You can now enter the *Bbox* for each speaker in *Multitalk* to precisely locate who is speaking. And to save some headaches the *Image Mask generator* will give you the *Bbox* coordinates of an area you have selected.
+- *Film Grain* post processing to add a vintage look at your video
+- *First Last Frame to Video* model should work much better now as I have discovered rencently its implementation was not complete
+- More power for the finetuners, you can now embed Loras directly in the finetune definition. You can also override the default models (titles, visibility, ...) with your own finetunes. Check the doc that has been updated.
+
+
+### July 10 2025: WanGP v6.7, is NAG a game changer ? you tell me
+Maybe you knew that already but most *Loras accelerators* we use today (Causvid, FusioniX) don't use *Guidance* at all (that it is *CFG* is set to 1). This helps to get much faster generations but the downside is that *Negative Prompts* are completely ignored (including the default ones set by the models). **NAG** (https://github.com/ChenDarYen/Normalized-Attention-Guidance) aims to solve that by injecting the *Negative Prompt* during the *attention* processing phase.

+Please dot not modify any file in this Folder.

+If you want to change a property of a default model, copy the corrresponding model file in the ./finetunes folder and modify the properties you want to change in the new file.
+If a property is not in the new file, it will be inherited automatically from the default file that matches the same name file.

 A Finetuned model is model that shares the same architecture of one specific model but has derived weights from this model. Some finetuned models have been created by combining multiple finetuned models.

-As there are potentially an infinite number of finetunes, specific finetuned models are not known by default by WanGP, however you can create a finetuned model definition that will tell WanGP about the existence of this finetuned model and WanGP will do as usual all the work for you: autodownload the model and build the user interface.
+As there are potentially an infinite number of finetunes, specific finetuned models are not known by default by WanGP. However you can create a finetuned model definition that will tell WanGP about the existence of this finetuned model and WanGP will do as usual all the work for you: autodownload the model and build the user interface.
+
+WanGP finetune system can be also used to tweak default models : for instance you can add on top of an existing model some loras that will be always applied transparently.

 Finetune models definitions are light json files that can be easily shared. You can find some of them on the WanGP *discord* server https://discord.gg/g7efUW9jGV

+All the finetunes definitions files should be stored in the *finetunes/* subfolder.
+
 Finetuned models have been tested so far with Wan2.1 text2video, Wan2.1 image2video,  Hunyuan Video text2video. There isn't currently any support for LTX Video finetunes.

-## Create a new Finetune Model Definition
-All the finetune models definitions are json files stored in the **finetunes** sub folder. All the corresponding finetune model weights will be stored in the *ckpts* subfolder and will sit next to the base models.

-WanGP comes with a few prebuilt finetune models that you can use as starting points and to get an idea of the structure of the definition file.
+
+## Create a new Finetune Model Definition
+All the finetune models definitions are json files stored in the **finetunes/** sub folder. All the corresponding finetune model weights when they are downloaded will be stored in the *ckpts/* subfolder and will sit next to the base models.
+
+All the models used by WanGP are also described using the finetunes json format and can be found in the **defaults/** subfolder. Please don’t modify any file in the **defaults/** folder.
+
+However you can use these files as starting points for new definition files and to get an idea of the structure of a definition file. If you want to change how a base model is handled (title, default settings, path to model weights, …) you may override any property of the default finetunes definition file by creating a new file in the finetunes folder with the same name. Everything will happen as if the two models will be merged property by property with a higher priority given to the finetunes model definition.

 A definition is built from a *settings file* that can contains all the default parameters for a video generation. On top of this file a subtree named **model** contains all the information regarding the finetune (URLs to download model, corresponding base model id, ...).

 You can obtain a settings file in several ways:
 - In the subfolder **settings**, get the json file that corresponds to the base model of your finetune (see the next section for the list of ids of base models)
- From the user interface, go to the base model and click **export settings**
+- From the user interface, select the base model for which you want to create a finetune and click **export settings**

 ## Architecture Models Ids
-A finetune is derived from a base model and will inherit all the user interface and corresponding model capabilities, here are Architecture Ids:
- *t2v*: Wan 2.1 Video text 2 
- *i2v*: Wan 2.1 Video image 2 480p
- *i2v_720p*: Wan 2.1 Video image 2 720p
+A finetune is derived from a base model and will inherit all the user interface and corresponding model capabilities, here are some Architecture Ids:
+- *t2v*: Wan 2.1 Video text 2 video
+- *i2v*: Wan 2.1 Video image 2 video 480p and 720p
 - *vace_14B*: Wan 2.1 Vace 14B
 - *hunyuan*: Hunyuan Video text 2 video
 - *hunyuan_i2v*: Hunyuan Video image 2 video

+Any file name in the defaults subfolder (without the json extension) corresponds to an architecture id.
+
+Please note that weights of some architectures correspond to a combination of weight of a one architecture which are completed by the weights of one more or modules.
+
+A module is a set a weights that are insufficient to be model by itself but that can be added to an existing model to extend its capabilities.
+
+For instance if one adds a module *vace_14B* on top of a model with architecture *t2v* one gets get a model with the *vace_14B* architecture. Here *vace_14B* stands for both an architecture name and a module name. The module system allows you to reuse shared weights between models.
+
+
 ## The Model Subtree
 - *name* : name of the finetune used to select
 - *architecture* : architecture Id of the base model of the finetune (see previous section)
 - *description*: description of the finetune that will appear at the top
 - *URLs*: URLs of all the finetune versions (quantized / non quantized). WanGP will pick the version that is the closest to the user preferences. You will need to follow a naming convention to help WanGP identify the content of each version (see next section). Right now WanGP supports only 8 bits quantized model that have been quantized using **quanto**. WanGP offers a command switch to build easily such a quantized model (see below). *URLs* can contain also paths to local file to allow testing.
- *modules*: this a list of modules to be combined with the models referenced by the URLs. A module is a model extension that is merged with a model to expand its capabilities. So far the only module supported is Vace 14B  (its id is *vace_14B*). For instance the full Vace model is the fusion of a Wan text 2 video and the Vace module.
+- *modules*: this a list of modules to be combined with the models referenced by the URLs. A module is a model extension that is merged with a model to expand its capabilities. Supported models so far are : *vace_14B* and *multitalk*. For instance the full Vace model is the fusion of a Wan text 2 video and the Vace module.
 - *preload_URLs* : URLs of files to download no matter what (used to load quantization maps for instance)
+-*loras* : URLs of Loras that will applied before any other Lora specified by the user. These loras will be quite often Loras accelerator. For instance if you specified here the FusioniX Lora you will be able to reduce the number of generation steps to -*loras_multipliers* : a list of float numbers that defines the weight of each Lora mentioned above.
 - *auto_quantize*: if set to True and no quantized model URL is provided, WanGP will perform on the fly quantization if the user expects a quantized model
+-*visible* : by default assumed to be true. If set to false the model will no longer be visible. This can be useful if you create a finetune to override a default model and hide it.
+-*image_outputs* : turn any model that generates a video into a model that generates images. In fact it will adapt the user interface for image generation and ask the model to generate a video with a single frame.
+
+In order to favor reusability the properties of *URLs*, *modules*, *loras* and  *preload_URLs* can contain instead of a list of URLs a single text which corresponds to the id of a finetune or default model to reuse.
+
+For example let’s say you have defined a *t2v_fusionix.json* file which contains the URLs to download the finetune. In the *vace_fusionix.json* you can write « URLs » : « fusionix » to reuse automatically the URLS already defined in the correspond file.

 ## Finetune Model Naming Convention
 If a model is not quantized, it is assumed to be mostly 16 bits (with maybe a few 32 bits weights), so *bf16* or *fp16* should appear somewhere in the name. If you need examples just look at the **ckpts** subfolder, the naming convention for the base models is the same.

-If a model is quantized the term *quanto* should also be included since WanGP supports for the moment only *quanto* quantized model, most specically you should replace *fp16* by *quanto_fp16_int8* or *bf6* by *quanto_bf16_int8*.
