The user wants a concise HTML summary of the provided news about StreamOPD. I need to extract key points from the title and description. Title: "StreamOPD: A Post-Training Recipe with Spatio-Temporal Cue Gating for Streaming Video Understanding" Description mentions: streaming video understanding, existing systems add memory/retrieval/compression, but training-free sliding-window baseline matches them. They fix a memory-free recent-window protocol and explore how far post-training alone can go. RL with verifiable rewards encourages long "think-then-answer" generations, while on-policy distillation... (text cuts off). I need to summarize in 2-4 sentences. Focus on: StreamOPD is a post-training method for streaming video understanding using spatio-temporal cue gating. It adopts a memory-free recent-window protocol, showing post-training alone can be effective. RL with verifiable rewards leads to long generations, while on-policy distillation... (I'll infer from context: likely they propose on-policy distillation as alternative). I'll write 3 sentences. Ensure technical language. Output only HTML with

and link. Let's craft: StreamOPD introduces a post-training framework for streaming video understanding that employs spatio-temporal cue gating within a memory-free recent-window protocol. The approach demonstrates that post-training alone can achieve competitive performance without inference-time memory or retrieval mechanisms. Reinforcement learning with ver
