Zero-Token 5.6x Faster Spatial Intelligence: MJev-Spatial Tops HF Daily Papers Alongside CUHK JIA-Lab's CarryOn Dual-Loop Robot Harness
Tackling high latency and safety failures in spatial VLM and embodied VLA deployment, MJev-Spatial (arXiv:2610.22276, #1 on HF Daily Papers with 350 upvotes) reformulates spatial judgment as single-pass native Q/K attention matching with zero added parameters—achieving 65.64% across 12 benchmarks while running 5.6x faster than its Qwen3.5-4B base—while CUHK JIA-Lab's CarryOn (arXiv:2610.21453) wraps frozen VLA policies in a dual-loop harness that cuts safety violations from 52.6% to 6.1% and raises physical recovery success from 13% to 80%.
Key Takeaways
- MJev-Spatial reuses pretrained Q/K projections for single-pass spatial classification with zero generated tokens, running 5.6x faster than its Qwen3.5-4B base with a top 65.64% average across 12 benchmarks
- Teacher-forced coarse-to-fine supervision and length-aware global batching boost MJev-Spatial training throughput by 30.8% across 12.3M spatial QA pairs
- CUHK JIA-Lab's CarryOn dual-loop VLA harness cuts safety violations from 52.6% to 6.1% and raises physical failure recovery success from 13% to 80%
