[ComfyUI]Flux：开源可商用F1！Apache2开源OpenFLUX1模型，已去蒸馏可微调

大家好我是安琪！！！在人工智能领域，开源模型的贡献对于推动技术发展和创新至关重要。今天，我们兴奋地宣布，ComfyUI团队再次引领潮流，推出了OpenFLUX1模型------这是Flux系列中首个开源可商用的模型，它已经去除了蒸馏过程，并且可以进行微调，为图像生成与反推技术带来了新的可能性。

OpenFLUX1模型基于Apache 2.0许可证开源，这意味着它不仅可供个人和研究机构免费使用，还可以被商业实体集成到他们的产品和服务中。以下是OpenFLUX1模型的一些亮点：

可商用：OpenFLUX1模型允许商业使用，为企业和开发者提供了更多的灵活性和创新空间。

去蒸馏：OpenFLUX1模型经过特殊处理，去除了蒸馏过程，使得模型更加精简高效。

可微调：用户可以根据自己的需求对OpenFLUX1模型进行微调，以适应特定的应用场景或优化性能。

OpenFLUX.1简介

近日由作者 @ostris 在huggingface上开源了Flux开源版本社区模型：ostris/OpenFLUX.1 。作者称：该模型是作者花费了大量的金钱在计算资源上进行训练，经过多轮迭代训练版本。OpenFLUX.1 模型是一个与FLUX.1 可媲美的新模型（实测与FP8也略逊一筹，但开源可加强后期训练 ）。并且是完全开源的 ，允许微调。

OpenFLUX.1 模型是在开源 FLUX.1-schnell 模型基础上进行微调的模型，并且已经去除了FLUX.1-schnell 模型蒸馏过程。Flux Schnell 是根据 Apache 2.0 开源许可的一个蒸馏模型。OpenFLUX.1 模型是一次在FLUX.1-schnell模型基础上尝试去除蒸馏过程，创建一个可以微调的开源商用许可的模型。

由于FLUX.1-schnell 模型的蒸馏过程已经被微调出来，OpenFLUX.1 模型使用了经典的 CFG。因此也需要一个与原始 FLUX.1 schnell 和 FLUX.1 dev 模型不同的管道。作者为此创建了新的管道，并且可以在代码仓库的 open_flux_pipeline.py 中找到。目前作者推荐：3.5 的 CFG 似乎效果很好。

OpenFLUX.1 ComfyUI体验

OpenFLUX.1 的使用方式和FLUX.1-schnell 类似，无需下载任何ComfyUI插件，使用和FLUX.1 一样的checkpoint方式加载 即可（测试不支持UNET加载方式，待进一步探索）。

• openflux1-v0.1.0-fp8.safetensors ：模型放置到 /ComfyUI/models/checkpoint/ 目录。下载地址为：https://huggingface.co/ostris/OpenFLUX.1/resolve/main/openflux1-v0.1.0-fp8.safetensors?download=true
• openflux1-vae.safetensors ：模型放置到 /ComfyUI/models/vae/ 目录，建议下载模型并rename。下载地址为:https://huggingface.co/ostris/OpenFLUX.1/resolve/main/vae/diffusion_pytorch_model.safetensors?download=true

OpenFLUX.1工作流

OpenFLUX.1 工作流如下所示，需要使用Flux的checkpoint方式加载 。并且在工作流中，笔者也加入了Flux DEV FP8 模型（OpenFLUX.1当前仅开放FP8模型。为了避免云存储资源FluxDev继续采用UNET加载方式）

比对工作流全貌：

注意：在运行OpenFLUX.1 模型时候，明显能感觉到运行速率会比较耗时 。出图质量与同等量化的Flux.1-DEV-FP8 模型会差一些。但是必究是社区开源可商用版本，可加强后期的数据集训练解决。

This is a real high-definition photo,This is a high-resolution, casual half-body portrait photo. The subject of the photo is a young woman wearing a white tank top and a denim jacket, with the sleeves of the jacket rolled up. She has black hair that falls over her shoulders. Her right hand is raised, shielding it from the sun, as if she is enjoying the seaside view. The background shows a beach and the ocean, with waves crashing against the shore and a small boat moored on the beach.

03. 善恶一念

This is a high-resolution,everyday scene image with a natural style,Create a movie poster with a dual-view design. On one side, depict a serene angelic figure against a pure white background, featuring a 20-year-old Chinese girl with an ethereal glow and delicate wings. On the other side, transform her into a captivating devil with striking horns and a fiery aura, set against a deep black background. Both images should seamlessly merge into one dynamic poster, capturing the contrast between light and dark, good and evil.
