   EC²-Bench Evaluates Edge-Cloud Collaboration for Long-Horizon AI Agents

   Northeastern University, Tsinghua University and China Mobile researchers released EC²-Bench, an open benchmark for edge-cloud collaboration in long-horizon AI agent tasks. It contains 128 executable digital-workspace tasks across six scenarios, with 100 tasks carrying fine-grained privacy annotations covering 3,385 sensitive information units, and evaluates task performance, resource costs and privacy exposure. The study compares four collaboration strategies; with Qwen3.5-9B, the best strategy raised the completion score from 39.12 under edge-only execution to 60.46 while using cloud resources costing 15% of the cloud-only setup.

   Preprint reports zero-shot steering transfer between text and image generation

   An arXiv preprint reports that steering vectors derived from one modality can transfer zero-shot to another in several unified multimodal models. The authors report bidirectional transfers between text-to-image and image-to-text generation across concepts including emotion and object size. They argue that steering provides a causal test beyond correlational alignment such as representational similarity, and that highly transferable vectors tend to point in similar directions for the same concept despite a gap between text and image representations. The preprint includes links to code, data and a demo; the supplied report does not identify the evaluated models.
