QUESTION — How can diverse execution trajectories from specialized agent harnesses be systematically scaled and reconstructed into reusable training data?
Three harnesses jointly solve 759 tasks, 34.3% more than the strongest individual harness in the recorded pool.
QUESTION — How can an adaptive runtime adjust execution plans during LLM reinforcement learning post-training to handle changing resource availability and distributed state?
Online TP/PP adaptation reduces average step latency by 27.7% relative to the initial fixed TP/PP layout with DP scaling on a real-data trace.
QUESTION — Can a general-purpose vision-language model operate a robot directly from observations without relying on external action experts or grounding tools?
MotorMind achieves 66.7% success on the base LIBERO-PRO suites and 53.8% under perturbations.
QUESTION — How can LLM agents synthesize reusable skills from past experience without discarding critical knowledge or retaining irrelevant instance-specific details?
ExpVoyager reframes agent skill synthesis as a dynamic navigation problem over past experience rather than relying on fixed procedural knowledge.
QUESTION — How can idea-driven automated scientific research be managed autonomously to organize evolving ideas and allocate computational budgets effectively?

QUESTION — How can historical frames be effectively selected for long-horizon video generation based on future information needs?
The paper presents FrameMorrow, a prospective frame selector that predicts a small set of prospective tokens representing future information needs to guide historical frame selection. By selecting historical frames according to their relevance to future needs rather than just the current content, FrameMorrow enables plug-and-play integration across diverse generative models, including closed-source architectures, with minimal inference overhead. Experiments across multiple benchmarks and generative models demonstrate consistent improvements in long-range consistency and visual quality.
