Gradium TTS vs Guava Daytona TTS: TTS API comparison
On P95 latency, Gradium TTS is faster: 104.3 ms for Gradium TTS against 584.8 ms for Guava Daytona TTS.
Listener Elo is not available for both models, so voice preference is not compared. A list price is missing for at least one of the two, so price is not compared.
Gradium TTS is ranked 1 of 23; Guava Daytona TTS is not in the multilingual speed ranking. Every comparison on this site uses Gradium TTS as its fixed reference, and no page says either model is better overall.

Ahead is computed from the figures only. A latency gap under 10 ms is a tie; listener Elo values whose 95% intervals overlap are a tie. A measure one benchmark does not hold is n/a for that model and is never estimated. See the methodology and each model page for sources.
