# Anima & Krea-2 GGUF Text-to-Image Workflows Collection

This repository provides highly optimized ComfyUI workflows tailored for the **Anima** and **Krea-2** model families, specifically utilizing **GGUF** quantized variants. Built entirely around ComfyUI's **native core nodes and GGUF loaders**, these workflows enable high-speed, high-fidelity Text-to-Image (t2i) generation while maintaining an exceptionally low VRAM footprint.

## Workflow Files & Overview

The repository contains the following production-ready workflow files.  
*(Note: `YYMM.x` in the file names represents the release year, month, and version number, e.g., `2606.1`)*

| # | File Name | Workflow Target | Key Features & Quick Notes |
|---|---|---|---|
| 1 | **Anima_t2i-javanoYYMM.x.json** | **Anima Text-to-Image (t2i)** | Pure Text-to-Image generation running on **Anima GGUF**. Optimized for ultra-fast sampling, high prompt adherence, and rich textural composition. |
| 2 | **Krea2_t2i-javanoYYMM.x.json** | **Krea-2 Text-to-Image (t2i)** | Native GGUF workflow for **Krea-2**. Tailored to enhance cinematic aesthetics, sharp details, and clean spatial upscaling. |

## Detailed Workflow Breakdown

### 1. Anima Text-to-Image Generation (`Anima t2i`)
Designed for high-resolution static image production utilizing Anima's native GGUF Text-to-Image architecture to minimize VRAM usage on consumer-grade GPUs.
* **Native GGUF Architecture:** Completely bypasses complex wrapper extensions, routing the model structure natively through ComfyUI's core sampling blocks (`Unet-Loader (GGUF)`).
* **Advanced Prompt Adherence:** Fully optimized KSampler configurations specifically balanced to harness Anima's unique aesthetic qualities, fine micro-details, and crisp compositions without cooking or oversaturating the output.
* **Flexible Resolution Control:** Set up with standard latent aspect ratio selectors to ensure optimal structural generation at native resolutions.

### 2. Krea-2 Text-to-Image Generation (`Krea-2 t2i`)
A dedicated workflow built to unleash the powerful aesthetic capabilities of the Krea-2 model within a lightweight GGUF framework.
* **Cinematic & Spatial Optimization:** Finetuned sampler settings that maximize Krea-2's core strengths—including enhanced lighting, realistic rendering, and crisp composition framing.
* **Efficient Inference Pipeline:** Leverages native GGUF quantization to handle Krea-2's advanced parameters smoothly, lowering hardware entry barriers while preserving premium image quality.

## Prerequisites & Installation

To ensure all workflows load correctly without errors, please ensure your environment is fully updated:

1. **ComfyUI Core:** Update ComfyUI to **v0.24.0 / Frontend 1.45.15** or newer. These workflows run entirely on ComfyUI's **native GGUF** implementation—**no extra model wrapper extensions are needed.**
2. **Custom Nodes:**
   * Ensure `ComfyUI-GGUF` (or the core node equivalent for loading GGUF model weights) and standard utility nodes (such as `ComfyUI-KJNodes`) are fully updated via the ComfyUI Manager. 
   * If any supporting node appears red upon loading, simply use ComfyUI Manager -> *Install Missing Custom Nodes*.
3. **Required Assets:**
   * **Base Models (GGUF):** Download the correct **Anima GGUF** and **Krea-2 GGUF** quantized weights and place them into your `models/unet/` or designated GGUF directory.
   * **Text Encoders / VAE:** Ensure your required Text Encoders (CLIP / T5) and target VAE are correctly configured in your `models/clip/` and `models/vae/` directories to process the text prompts accurately.
