StepFun: API-Anbieter-Benchmarking & Analyse
Analyse der API-Anbieter von StepFun anhand von Leistungskennzahlen, einschließlich Artificial Analysis Word Error Rate Index, Geschwindigkeit und Preis.
Artificial Analysis Word Error Rate (AA-WER) Index nach API
Artificial Analysis Word Error Rate (AA-WER) Index nach API
% of words transcribed incorrectly · Lower is better · AA-WER v2 incorporates 3 datasets: AA-AgentTalk (50%), VoxPopuli-Cleaned-AA (25%), Earnings22-Cleaned-AA (25%)
Hinweis: Wenn ein Modell bei Earnings22 aufgrund von Zeitlimits Audio in voller Länge nicht zuverlässig verarbeiten kann, teilen wir es in Segmente von ca. 9 Minuten auf (relevant für: Nova 2 Pro, Amazon, GPT-4o Transcribe, OpenAI und GPT-4o Mini Transcribe, OpenAI). Bei Modellen mit noch kürzeren Zeitlimits teilen wir es in Segmente von ca. 30 Sekunden auf (relevant für: Canary Qwen 2.5B, NVIDIA, Inworld STT 1).
