AssemblyAI Models
Every AssemblyAI speech and audio model, explained in plain English. AssemblyAI's speech models — the Universal transcription family used for meeting and call transcripts.
What are the AssemblyAI models?
AssemblyAI releases new AI models regularly, and the announcements are usually written for engineers. We explain each model in language anyone can follow: what it does well, what it costs, what it can handle, and how it compares to the one before it.
