Developer fixes Anthropic client bug blocking asyncio event loop

By PulseAugur Editorial · [1 sources] ·

The problem was initially masked by single-user testing, where the blocking call appeared normal. The developer identified the issue by enabling asyncio debug mode and implementing a loop-lag monitor, ultimately resolving it by switching to the asynchronous Anthropic client and using `async for` for streaming responses.

    <p>With one user on the server, my voice AI answered in 0.9 seconds. With eight users, the last person in line waited 11.4 seconds, and it sounded broken. The model, the network and the speech vendor were all fine. The problem was one line, <code>client = Anthropic()</code>, call…
