LEAP keeps hour-scale audio-video QA out of one giant context: 4.5–16.8% over the Qwen3-Omni-30B baseline and transfer to MiniCPM-o 4.5
LEAP splits an hour-scale recording into fixed-duration blocks, runs a lightweight localization pass per block to score short candidate windows, then re-encodes only the top-ranked windows in a single bounded answer pass, so the answer input and peak context stay independent of recording duration; across several AVQA benchmarks it improves over the Qwen3-Omni-30B-A3B baseline by 4.5–16.8% and transfers to MiniCPM-o 4.5, surpassing its published results by 3.1–13.0%.
