LongCat Image Model in ComfyUI -- Full Workflow, GGUF vs BF16, Real-World Tests & Review

🔥 LongCat Image Model Tested in ComfyUI (Complete Workflow & Benchmark) In this video, we test the LongCat Image 6B model inside a native ComfyUI workflow, exploring both BF16 safetensors and GGUF quantized versions (Q3 to Q8) to evaluate performance, realism, speed, and VRAM efficiency. LongCat-Image is a powerful open-source bilingual (Chinese-English) foundation model focused on photorealism, efficient deployment, strong text rendering, and developer accessibility --- all at just 6B parameters. ------------------------------------------------------------------------ 🚀 What's Covered in This Video ✅ Complete ComfyUI LongCat workflow setup\ ✅ Required models (LongCat BF16 / GGUF, Qwen 2.5 7B VL, Flux VAE)\ ✅ Portrait realism test\ ✅ Cinematic Hollywood landmark test\ ✅ Geometric abstract mosaic symmetry test\ ✅ Text rendering accuracy test (blackboard typography)\ ✅ Football action scene with sponsor logo accuracy\ ✅ Hyper-realistic Seattle HDR winter cityscape\ ✅ Honest review of realism, lighting, prompt adherence & text rendering ------------------------------------------------------------------------ ⚙️ Model Highlights 6B parameter architecture\ BF16 size \~12.5GB\ GGUF quantization from 2.8GB (Q3) to 6.7GB (Q8)\ Strong Chinese and English rendering\ Photorealistic image generation\ Efficient VRAM usage\ Native ComfyUI support ------------------------------------------------------------------------ 🔹 Download Links: diffusion_models BF16: https://huggingface.co/Comfy-Org/Long...
