Well, I jumped the gun yesterday. I started receiving numerous reports that speech generation had stopped working. After looking into it further, we found that the old models created by OpenAI appear to be throttled. This isn’t official, but it’s what we discovered. Generating a 20-second recording with the old model used to take 10 seconds or less; today, it's taking 137 seconds! FS PBX API requests time out after 60 seconds, so generation fails. A new model, which is significantly more expensive, takes only 6 seconds today. We had no choice but to switch to the new models in the latest commit.
