ComfyUI posts that Transformers and diffusion transformers share a historical rhyme

ComfyUI says on X that history does not repeat but often rhymes, hinting that the Transformer and the Diffusion Transformer share that pattern.

The post does not explain the comparison in further detail.

The post links to a Brian Armstrong account of Coinbase fine-tuning the open-weight Qwen3.5-9B model on internal data. Armstrong says the tuned model outperformed frontier models on fraud prevention at lower cost and higher speed.
