Artificial Analysis
Artificial Analysis is a community‑based arena leaderboard that evaluates TTS models by showing the outputs of two models to voters. Voters indicate the preferred audio; the votes are tallied and converted into Elo scores (Bradley–Terry) to rank the models. Artificial Analysis ranked Claude Opus 5.5 first Artificial Analysis ranked Muse Wonder Full Artificial Analysis ranked Muse Wonder Artificial Analysis scored Kimi K3.1 Pro 55 (against 53 for other models) Artificial Analysis placed Kimi K3.1 Pro fourth on its Intelligence Index Artificial Analysis calls GPT-6.1 Terra a new benchmark for intelligence per dollar Artificial Analysis ranks GPT‑6.1 Terra in its Intelligence Index (48 points) Artificial Analysis ranks GPT‑5.6 Terra in its Intelligence Index (42 points) X/Artificial Analysis provides the data for Artificial Analysis’s reports X/Artificial Analysis provides the data for Artificial Analysis’s reports Artificial Analysis overhauled its Intelligence Index· Entity summary generated by Graphiti
