When resolution doubles, the attention computation the model must handle often grows fourfold or more, causing elapsed time to increase non-linearly.

VerifiedTransformer架构的自注意力机制在处理长序列时面临二次方复杂度的计算开销，上下文长度翻倍则计算量增长四倍78% similarUnverified14倍的提升由多因子叠加而来：批处理贡献3-4倍、内存优化贡献1.5-2倍、会话复用与线程调优再叠加若干76% similarVerifiedThe self-attention mechanism causes computational complexity to grow quadratically with sequence length, so expanding the context from 1,000 to 4,000 tokens increases the computation by 16 times.75% similarUnverifiedThe more sampling steps a diffusion model uses, the more thorough the denoising and the higher the image quality, but the computational time also increases proportionally.75% similar
