Choose the evaluation track
Use Progressive for fixed-prompt long-horizon behavior and Interactive for runtime response, retention, and reuse.

Official results
Compare systems by metric.
Choose a metric below to rank systems. Metrics use different scales and are therefore reported separately.
Quality, alignment, continuity, and efficiency metrics applied across both tracks.
Metric-wise ranking
Quality & Alignment
Perceptual quality and semantic or temporal correspondence between audio and video.
Ranked by Visual AestheticsHigher is better
Leaderboard unavailable
The leaderboard data could not be loaded.
Reading the ranks. Click any metric header to rank by that metric. Published three-decimal ties use competition ranking (for example, 1, 1, 3). PVRL and PARL are conditional on successful target achievement and should be read with PVUAR and PAUAR.
HDF is evaluated only when its required source state was established. NBC, FPS, and TTFC are unavailable for PixVerse R1, HappyOyster, and Odyssey-2 because their web interfaces do not expose the required traces.

How to read StreamAV-Bench
Performance is a profile, not a single number.
Read score and drift together
High quality or fulfillment can coexist with temporal drift. Read absolute scores alongside their drift counterparts.
Read success rate with latency
Low conditional latency does not guarantee reliable updates. Read response latency together with achievement rate.
