How we rate models
- Quality. Three brains is top, one is basic. We anchor the rating on Word Error Rate on FLEURS / LibriSpeech — the standard speech-recognition accuracy test — how often the model mistakes a word.
- Fast. Shown when transcription runs at least 10× faster than the audio plays. Not every model qualifies.
- $$$$$$
- Cost. Single dollar is the cheapest tier (green), three dollars is the priciest (amber). We bucket models relative to the other models you can pick from on Zo, so the tier is meaningful across providers.
On Zo, you can choose between all the leading AI models for chatting, research, coding, and generating media. We believe in giving you the power to explore different models so that you can get the best results for any task.
