Lumi 503 error "The model is overloaded" when asking questions using Gemini key

After asking Lumi questions (after adding Google AI Studio key), the first 1-2 responses work, then soon I get Chrome console errors as if your model is overloaded. Is this expected, because Gemini should not get overloaded so easily, or do you have a separate model? I recommend you look at your logs for the 503 errors.

Failed to load resource: the server responded with a status of 503 ()

hook.js:608
Error getting Lumi response: FirebaseError: Model call failed: 503 UNAVAILABLE. {'error': {'code': 503, 'message': 'The model is overloaded. Please try again later.', 'status': 'UNAVAILABLE'}}

bundle.js:65
POST https://us-central1-lumi-459321.cloudfunctions.net/get_lumi_response 503 (Service Unavailable)

bundle.js:982
Error getting Lumi response: FirebaseError: Model call failed: 503 UNAVAILABLE. {'error': {'code': 503, 'message': 'The model is overloaded. Please try again later.', 'status': 'UNAVAILABLE'}}

Let me know if unable to reproduce, or see the 503 errors in your logs, and I can provide the source Arxiv PDF.

Start by reviewing Firebase logs for the get_lumi_response Cloud Function and reproduce the failure after the first 1-2 responses. Compare the logs with the 503 errors shown for bundle.js and Chrome. Done means the cause of the model overload response is identified and the issue has a verified resolution or documented limitation.
