✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

we introduce Render-of-Thought (RoT), the first framework to reify the reasoning chain by rendering textual steps into images, making the latent rationale explicit and traceable... achieves 3-4x token compression and substantial inference acceleration compared to explicit CoT... maintains competitive performance

C2weakest assumption

leverage the vision encoders of existing Vision Language Models (VLMs) as semantic anchors to align the vision embeddings with the textual space without incurring additional pre-training overhead

C3one line summary

RoT renders CoT reasoning text as images and aligns them via VLM vision encoders to achieve 3-4x token compression and faster inference with competitive accuracy.
