Marc Zhang Greetings & Welcome to Microsoft Q&A Forum!
We have been seeing abnormally high latencies when using gpt-4 and gpt-4-turbo models. In some extreme cases, the latency is more than 1 minute. This has become unusable for us at the moment. Anyone experiencing similar issues or know what could be the cause of this? For context, our input token length is about 6k tokens. We use function calling in our requests. We are not close to our throughput quota. We have multiple deployments in different regions, and face the same issue.
I understand that you are seeing high latency. Latency is expected if you are using GPT4 models considering that gpt-4 has more capacity than the gpt-3.5 version.
As of now, we do not offer Service Level Agreements (SLAs) for response times from the Azure OpenAI service.
As Charlie mentioned, I would suggest you, please check the documentation on improving the performance and latency.
Also, Here are some of the best practices to lower latency:
- Model latency: If model latency is important to you we recommend trying out our latest models in the GPT-3.5 Turbo model series.
- Lower max tokens: OpenAI has found that even in cases where the total number of tokens generated is similar the request with the higher value set for the max token parameter will have more latency.
- Lower total tokens generated: The fewer tokens generated the faster the overall response will be. Remember this is like having a for loop with
n tokens = n iterations
. Lower the number of tokens generated and overall response time will improve accordingly. - Streaming: Enabling streaming can be useful in managing user expectations in certain situations by allowing the user to see the model response as it is being generated rather than having to wait until the last token is ready.
- Content Filtering improves safety, but it also impacts latency. Evaluate if any of your workloads would benefit from modified content filtering policies.
I Hope this helps. Please let me know if you have any further queries.
