Google AI "Unavailable" error. (Code 503)

Most of my workflows have been having execution issues after adding Google AI Studio.
This is the free model, but they fail well below the threshold.
Anyone familiar with the issue below? What are some suggestions for a resolution?
(FYI, I switched from OpenAI for cost reasons)

Error message:
Step Name: Google AI Studio (Gemini) > Generate Content
Connection Name: Google AI Studio (Gemini) #1
Task Error Detail:

{
"error > code": 503,
"error > message": "The model is overloaded. Please try again later.",
"error > status": "UNAVAILABLE"
}

Current model:

Will other models work with the existing API?

Thanks

Temporary Solution: Try using a different model every 5 requests.
Permanent Solution: You’ll need to contact support, although people have been experiencing this error for over a year.

This is a known issue with Gemini. You can see it discussed here: https://discuss.ai.google.dev/t/model-is-overloaded/59817/18

Thanks for your input.
It's almost unbelievable that such a major issue is unresolved for this long.

What model would you recommend to replace Gemini AI?
I tried OpenAI, but GPT 5 costs add up fast.

You can try using a different model like GPT-4o Mini, which is more cost-effective.
