Thanks for the comment! Yes we should have specified Parakeet v2. The latest Parakeet v3 is in the main leaderboard (not yet in long form @Steveeeeeeen ), and has similar RTFx so there wouldn't be trade-off on multilingual (but dip in English performance).
First of all thanks for the leaderboard, very useful ressource.
It would be a very nice addition to have an "efficiency" column that directly shows the AverageWER / RTFx ratio, or a 2D plot of it, showing the "Pareto frontier", as is often done for LLMs nowadays.
Technology changes humanity
This breakdown captures how rapidly ASR is evolving, especially the clear divide between LLM-enhanced accuracy and the blazing throughput of CTC/TDT systems. The post also highlights the ongoing tradeoff between multilingual coverage and single-language specialization, which is crucial for real-world deployment scenarios like Fastest Trains or long-form transcription workflows. With the Open ASR Leaderboard adding multilingual and long-audio tracks, it’s becoming one of the most reliable ways to gauge practical ASR performance today.
why there is no models from China?
Great stuff, thank you! How do you view the longform results on the board?
