Krea2 EchoRC 是一个面向 Krea2 / FLUX 架构模型 的 ComfyUI 推理增强节点。
Krea2 EchoRC is a ComfyUI inference enhancement node designed for Krea2 and FLUX-based diffusion models.
EchoRC 不修改模型权重，而是在 Krea2 采样过程中加入一个动态记忆系统，让模型在生成过程中保留部分历史状态信息，从而增强不同采样阶段之间的信息传递。
主要用于提升：
复杂提示词理解
场景一致性
多物体关系
细节稳定性
EchoRC does not modify model weights. Instead, it introduces a lightweight dynamic memory system during Krea2 sampling, allowing information from previous denoising stages to influence later generation steps.
Designed to improve:
Complex prompt consistency
Scene coherence
Object relationships
Detail stability
参数说明
Reservoir Size
控制动态记忆容量。数值越大，保存的信息越多，但计算量增加。
Rho (Spectral Radius)
控制记忆状态的稳定性和持续时间。越高，历史信息保留越久。
Leak Rate
控制新信息与旧状态的混合比例。越高，记忆衰减越慢。
Input Scale
控制输入信息进入 EchoRC 的强度。
Strength
控制 EchoRC 对最终生成结果的影响程度。
Start Block / End Block
控制 EchoRC 作用于 Krea2 Transformer 的范围。
Seed
控制 EchoRC 动态状态初始化，使结果具有可复现性。
Parameters
Reservoir Size
Controls the memory capacity of the reservoir. Higher values store more information but increase computation.
Rho (Spectral Radius)
Controls memory stability and retention length.
Leak Rate
Controls the balance between previous memory states and new information.
Input Scale
Controls the strength of input signals entering the reservoir.
Strength
Controls the overall influence of EchoRC on generation.
Start Block / End Block
Defines which Krea2 Transformer blocks are affected.
Seed
Controls reservoir initialization for reproducible results.
Description
第一版的代码实际上有实现上的逻辑漏洞，我现在已经解决了问题，本节点现在会更显著的影响图片生成，带来更好、更显著的优化，另外测试表明，本节点会加速生成速度（可能是偶发现象，但是在四次测试中均提升了大约6%的速度），如果您觉得本节点好用，欢迎分享到你的论坛或者聊天室。
本节点可能偶尔会带来负优化，灵活调整参数，或者开关本节点以达到您需要的效果。
The first version of the code actually had a logical flaw in its implementation, which I have now resolved. This node now significantly impacts image generation, bringing better and more noticeable optimizations. Additionally, testing shows that this node accelerates generation speed (this may be an occasional phenomenon, but it improved speed by approximately 6% in four tests). If you find this node useful, please feel free to share it on your forums or chat rooms.
This node significantly optimizes image detail and image expressiveness. You can see these changes in the example images. I believe this node has achieved all my expected goals. If you have any good optimization ideas, or would like to discuss technical issues with me, please feel free to send a private message or email to [email protected].
This node may occasionally bring negative optimizations. Adjust the parameters flexibly, or toggle this node on and off to achieve the desired effect.
