The answer is in the correct format, and should stream properly, but your ask_ai response is taking a whopping 15.5 seconds. For a site with so few topics, I don’t think this is a good experience.
Ask AI has a 20-second deadline for the whole request, including retrieval, so I suspect it is timing out after showing the title and related topics.
I’d suggest switching back to the previous model, or using a provider with more consistent response times, to see if the answer appears. That would help confirm whether the request is timing out.
