About ToneBench
Where this benchmark comes from, and who is behind it.
ToneBench grew out of the scripts we write for our YouTube channel, and the broader work we do at Towards AI helping people and companies actually build with AI. We pick writing models for this exact job every week, so we wanted a measurement we could trust more than a generic leaderboard.
