Spectral-Progressive Thought Flow for Lightweight Multimodal Reasoning

In three linesSpecFlow introduces a lightweight multimodal spatial reasoning framework representing intermediate visual thoughts in fixed-size discrete cosine space. Classifier-free guidance enables autoregressive textual thoughts to steer visual state updates without context expansion. Achieves competitive reasoning performance while reducing computation and KV cache costs by up to 2.1×.
