✓ 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

RIME substantially outperforms prior generative embedding models while significantly reducing the length of thinking.

C2weakest assumption

The rewrite step preserves necessary semantic information for downstream retrieval while remaining retrieval-friendly; this is asserted but not derived in the abstract.

C3one line summary

Rewrite-driven generation with alignment and RL produces shorter, more effective generative multimodal embeddings than CoT methods on retrieval benchmarks.
