The Hugging Face Open ASR Leaderboard exists, but the figures from that board were not collected in this pass.
In a one-off citation from Artificial Analysis, in the latest version we checked, Alibaba's Fun-Realtime-ASR-preview shows an AA-WER of 1.7%, at US$2.82 per thousand minutes. Source: Artificial Analysis (artificialanalysis.ai). The metric weights AgentTalk at 50%, VoxPopuli at 25% and Earnings22 at 25%, a mostly English mix, and the "preview" label itself can change. For a meeting, an interview or support in pt-BR, a test on your own audio still comes ahead of that cut.
