Do 3D Large Language Models Really Use 3D Evidence?

Recent 3D Large Language Models (3D-LLMs) have shown strong performance on scene question answering with extensive post-training. Yet, existing benchmarks rarely evaluate how 3D-LLMs respond to referential ambiguity, insufficient scene evidence, or false presuppositions, obscuring whether their responses are grounded i...

From Global Alignment to Local Grounding: Zero-Shot Chinese Character Recognition with Radical Verification

This work proposes a global-to-local two-stage framework for zero-shot Chinese character recognition that achieves state-of-the-art performance under the character-level zero-shot setting, and shows that the explicit geometric priors and radical-level verification provide complementary improvements.
