I spent three weeks debugging an AI chatbot. It kept timing out.
The problem was not the API. The problem was how I called it.
Last quarter, I built a customer support chatbot for a SaaS product. It worked well in testing. In production, it failed.
Users waited 20 seconds for a single chunk of text. Then, 15% of requests hit a 504 Gateway Timeout. Users left the chat mid-response.
I tried several bad fixes first:
- I increased the timeout to 60 seconds. This only made failures take longer.
- I used synchronous retries. This caused memory spikes and server queues.
- I tried polling. The API did not support it.
The solution was streaming.
Streaming allows the model to send tokens as they generate. This solves two problems:
- Perceived latency drops to near zero. The user sees text within 200ms.
- Timeouts become easier to manage. You can handle the stream in parts.
I built a robust system using Python and aiohttp. Here is the logic:
- Open a streaming connection.
- Read chunks in real time.
- Track the last token index.
- If the connection drops, use a retry delay.
- Reconnect and resume from the last position.
After I deployed this, timeout errors dropped from 15% to less than 0.5%.
Three lessons I learned:
- Read the API docs thoroughly. I skipped the streaming section and paid for it.
- Add observability early. You need metrics on latency before users complain.
- Design for failure. Every network call must handle partial failures.
Streaming is not a magic fix. Not every API supports it. It also adds code complexity. If your API returns answers in under 2 seconds, you do not need it.
How do you handle unreliable AI responses?
