Are all the TTS models unavailable? None of them seems to respond successfully and they all have just “–” for latency, throughput and 0% for uptime? Thanks

Welcome to the community! I can’t reproduce this on my side, the TTS models I checked are responding successfully for me. Also right now there isn’t anything on OpenAI’s status page, everything seems fully operational. Does it fail for you both in the Playground and through direct API calls or on…

It fails through API calls. The only combination I was able to use was model=“sesame/csm-1b”, voice=“alloy” and response_format=“mp3”. Are there any information on which voices and formats available for each model?

I am sorry they seem all working. it was my fault, I need to read the document carefully and use the right voice names. Thanks anyway for letting me know all is working as expected :slight_smile:
