AI Builders, Beware of Hidden Risks with Gemini 2.5 Pro and…

Gemini 2.5 Pro is one of the best AI models out there in terms of cost-to-performance.
But have you ever thought about what happens if your project gets DDoSed or your API key gets exposed?

Be ready for a six-figure invoice.

You might assume you can set a hard spending cap like with OpenAI or Grok - but not on Google Cloud. Google only allows alerts and quotas, not true spending limits. There are probably some reasons for that… but it is also a big reason to be careful.

So what can you do?

1) Count API requests on your side and stop them when the limit hits.

Not precise, and it does not help if your API key is stolen.

2) Use Google Cloud Billing API to disable billing when reaching the limit.

Still delayed - you will likely be charged before it takes effect.

3) Best solution (IMO): Use a bridge like OpenRouter.ai

It acts as a unified API gateway for hundreds of AI models.
You can actually set a real spending limit on your account.
The fee is around 5.5% on top of model prices - worth the peace of mind.

As for reliability?

OpenRouter is already valued at over $500 million - not bad for a young startup that is quickly becoming the backbone of safer AI infrastructure.
