Audio preference Cap is the peer rank for this modality — preference arenas and measured boards (VBench / Open ASR / Open Media categories) when they exist. Empty axes stay blank; Cap never copies an overall score into realism or motion.
Open Media Arena evaluations (Text-to-Image, LMArena I2V, TTS Arena, …) feed this portfolio when the catalog worker has matched this slug. Cards below list Cap axes, arena scores, and evidence sources — not the Language Model Matrix.
NOT RANKED YET
We only rank a model once it has enough published benchmark results to compare fairly. Everything below is what we do know: pricing, news and any scores that have been published.
