Has anyone noticed that Haiku 3.5 has 2-3 second additional latency in responses vs sonnet 3.7 which shows 600ms more latency in the preview, but is 2-3 seconds faster in most responses than Haiku in Vapi. Since Haiku is supposed to be significantly faster than sonnet, curious why with VAPI, Haiku is greater delays and latency. Something seems off, It has been slow for a while with haiku, and switching over to sonnet made it much faster, switching back to haiku slows it down again significantly. Seems like something on the VAPI end. Any solutions to fix this?
