Civitai detects the NVFP4 as BF16 quantization and this cannot be changed; it is not BF16.<span style="background-color:rgb(37, 38, 43);color:rgb(193, 194, 197);font-family:-apple-system, BlinkMacSystemFont, &quot;Segoe UI&quot;, Roboto, Helvetica, Arial, sans-serif, &quot;Apple Color Emoji&quot;, &quot;Segoe UI Emoji&quot;;font-size:14px">The INT4 ConvRot SR file was also added.INT4 ConvRot SR – Performance Edition This quantization is primarily intended for NVIDIA GPUs that can efficiently accelerate low-precision INT4 workloads. Performance gains depend heavily on your GPU architecture, inference backend, and available kernels.On my RTX 4090 (Ada Lovelace), at 1152×1440 resolution, this version reduced generation time from approximately 11 seconds with FP8 to ~4.7 seconds, using the same generation settings.The model size is also significantly reduced, from roughly 12 GB with FP8 to just under 7 GB, making it considerably lighter in terms of storage and VRAM requirements.INT4 ConvRot SR trades some numerical precision for substantially lower memory bandwidth and much faster inference when the hardware/backend can take advantage of it. A small loss of fine detail may become noticeable compared with the original FP8 model, so I recommend FP8 for maximum quality and INT4 ConvRot SR for maximum speed.Recommended: modern NVIDIA RTX GPUs with good INT4/low-precision acceleration, especially when supported by optimized inference kernels. Results may vary significantly between GPU generations and software backends.The INT8 and CONVROT quantizations are now up.IOR v2 — GGUF Q4_K EditionIOR v2 is now available in GGUF Q4_K, bringing the same model to users with more limited VRAM without requiring the full FP8 checkpoint.This version was quantized directly from the original IOR v2 model. Despite the much more aggressive quantization, my testing showed surprisingly little visual degradation. The characteristic realism, natural skin detail, lighting, textures and overall photographic behavior of IOR v2 remain remarkably close to the original.The Q4_K version offers a significantly lighter alternative for users with less VRAM.FP8 remains the recommended version if you have enough VRAM and want the original checkpoint at its highest available fidelity. GGUF Q4_K is intended as the more accessible option.Same IOR. Less VRAM.NVFP4 VersionNVFP4 is NVIDIA’s 4-bit floating-point quantization format, designed primarily for Blackwell-generation GPUs such as the RTX 50 series, where native FP4 hardware acceleration can provide the greatest benefit.This version significantly reduces model size and VRAM requirements while preserving most of the original model quality. It may also run on older NVIDIA GPUs through supported inference implementations, although they do not have Blackwell’s native FP4 acceleration.This IOR v2 NVFP4 was converted directly from the original checkpoint. In my testing it produced valid generations at essentially FP8-like speed, despite the substantially smaller model size.Recommended for: RTX 50-series / Blackwell GPUs and users looking for a lower-VRAM SafeTensors version.For maximum fidelity: use the original FP8 version.Recommended Settings<ul><li>Width and height: 896*1152 base and 1152x1440 Hires</li><li>CFG Scale: 1</li><li>Steps: 8</li><li>The sampling method i use is Euler-SGM Uniform, You can also try ER SDE-SGM Uniform for a bit more rawness.</li></ul><h2 id="about-this-version">About this version</h2>IOR V2 — Imitation of RealityIOR V2 is a major evolution of the original IOR for Krea2, built around one simple idea: reality is imperfect.This version pushes the model further away from the polished, overly controlled look commonly associated with AI-generated imagery and toward something that feels photographed rather than generated.IOR V2 improves natural skin and material texture, believable human expressions, complex lighting, photographic depth, environmental coherence and fine detail, while preserving Krea2's excellent prompt understanding and versatility.But perhaps the most important change is not simply image quality.

Its mission is simple: create images so clean, detailed, and naturally balanced that they become almost indistinguishable from professional photographs.IOR Krea2 V1 has been carefully optimized to maximize resolution, fine detail, and image fidelity. Every aspect of the model has been refined to produce sharper textures, cleaner edges, realistic lighting, and highly accurate materials without sacrificing the natural look that makes an image believable.The result is a model capable of generating photographs with exceptional clarity while preserving authentic colors, realistic skin, physically convincing lighting, and true-to-life environmental details.<h2 id="why-you'll-love-ior">Why You'll Love IOR</h2><ul><li>Exceptional high-resolution performance.</li><li>Outstanding detail retention, even in complex scenes.</li><li>Clean, realistic images with minimal artifacts.</li><li>Highly accurate lighting, materials, and textures.</li><li>Natural skin tones and lifelike facial details.</li><li>Excellent consistency across a wide variety of prompts.</li><li>Optimized for photorealism without looking overprocessed.</li><li>Perfect for portraits, architecture, interiors, products, fashion, landscapes, automotive, and commercial-quality photography.</li></ul><h2 id="the-philosophy">The Philosophy</h2>IOR stands for Imitation of Reality, and that is exactly what this model was built to achieve.Instead of emphasizing stylization or dramatic effects, IOR focuses on reproducing the subtle visual characteristics that make a photograph feel genuine.
