We have an API Service that is utilizing Perplexity’s chat completion via the official NodeJS SDK. We’re using the sonar-pro model with high reasoning effort. With no changes on our end, we’ve started noticing a huge increase in latency from perplexity API, we were originally averaging requests in the 3-10 second range and now we’re seeing 30+ second requests with the exact same prompt / configurations. Has something changed internally and is this is expected? is there a service degradation that we should be aware of? I am happy to provide any additional details or information to help figure this out, just hoping to get some clarity as this is impacting our customers.
