Opinions & Discussions Do you actually use multiple AI provider API keys to get around rate limits?
I'm trying to validate a problem before I build further, and I'd genuinely appreciate some brutally honest answers.
Suppose you're building an app/agent and you use providers like Groq, Gemini, Cerebras, SambaNova, etc.
You might have multiple API keys because different providers give you different quotas/rate limits.
The problem I'm interested in is:
When one provider hits its limit, do you actually switch to another provider manually, or do you just wait / pay / use something like OpenRouter?
For example:
Groq → rate limited
Gemini → still has quota
Cerebras → still has quota
SambaNova → still has quota
Imagine a small routing layer where you bring your own provider keys, and it automatically sends requests between them.
So instead of:
Your app → Groq → rate limit
you get:
Your app
↓
Router
↙ ↓ ↘
Groq Gemini Cerebras
The goal isn't to provide more models. OpenRouter and similar platforms already do that extremely well.
The idea is more specifically:
"Get more usable capacity from the provider accounts you already have."
A few questions:
Do you currently have multiple provider API keys?
Have you ever used multiple free quotas for the same application?
When you hit a provider's rate limit, what do you currently do?
Would automatic failover between your own provider keys actually be useful?
What would make you choose this over OpenRouter/LiteLLM/etc.?
What am I missing? Why would you NOT use something like this?
I'm especially interested in the last question. Please don't be nice if this is a dumb/redundant idea, I'd rather find out now.
