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

TorchUMM, the first unified codebase for comprehensive evaluation, analysis, and post-training across diverse UMM backbones, tasks, and datasets.

C2weakest assumption

That the chosen models, tasks, and datasets are representative enough to produce fair comparisons and that the unified interface does not introduce implementation-specific biases that distort model capabilities.

C3one line summary

TorchUMM is the first unified codebase and benchmark suite for standardized evaluation of diverse unified multimodal models on understanding, generation, and editing tasks.
