🪄 Draft Before Generation

We propose Draft-as-CoT (DraCo), a novel interleaved reasoning paradigm that fully leverages both textual and visual contents in CoT for better planning and verification.

Our method 🎨 first generates a low-resolution draft image as a preview, providing more concrete and structural visual planning and guidance.

Then, we 🔎 employ the model’s inherent understanding capability to verify potential semantic misalignments between the draft and input prompt, and 🖼️ perform refinement through selective corrections with superresolution.
