By default, the upstream "ai" module (https://github.com/vercel/ai/) is returning the response from the Azure OpenAI API with a "text/plain" Content-Type. If your azurechat instance is hosted behind a cloudflared tunnel (maybe just Cloudflare in general, I haven't tested this), the response will be buffered by cloudflare(d) and returned all at once.
Other than not being the expected experience, this can lead to timeouts (cloudflare default = 100s) if the response is long or slow to generate. If the response is streamed, there should be enough data flowing to avoid this timeout.
Cloudflared looks for the Content-Type response header and if it is "text/event-stream" it will know not to buffer the response but to send it immediately to the requestor. Reference.
