TTS API very slow today, even timing out
OpenAI Developer Community
March 7, 2026
Hey there,
for the first time ever I am suddenly seeing lots and lots of timeout exceptions when generating TTS via the api. I am using the model “gpt-4o-mini-tts-2025-12-15“.
Anyone else experiencing this? Generation of a short Sentence “Hey, my name is Mark and I am available” is taking 15-20 seconds.
Can’t be rate limited, I am at 0.62 cents today.
