We just implemented AI Gateway using the Universal endpoint, with both OpenAI and Anthropic models in the list. Is there a way to test that the fallback is working (short of waiting for the next OpenAI service outage)? We've tried providing an invalid API key for the primary service from a local environment, but it seems like this would return a different error. What are the recommended ways to test different failure modes?

Also wondering what the "predetermined request timeout" is. The documentation on this is just a broken link (https://developers.cloudflare.com/ai-gateway/configuration/fallbacks/#request-timeouts:~:text=predetermined%20request%20timeouts)

Kathy•3/7/25, 7:28 PM

got it, we currently don't have per request control to disable guardrails. so thanks for sharing your use - something for us to think about

as for how to help right now, since guardrails is at the gateway level, you could use two gateways - one for embedding with guardrails on. one for queries wiht guardrails off. sorry not the cleanest

nclevenger•3/9/25, 9:59 AM

When using openrouter, the duration values are way lower than reality ... many of these requests are taking multiple seconds (or even 10s of seconds) ... and even the fastest ones are coming back in mid-to-high hundreds of milliseconds while AI Gateway isn't reporting anything over 225ms ...

The other [minor but annoying] issue with AI Gateway + OpenRouter is that the model names are cut off very short, and given the

{model}:{keyword}

{model}:{keyword}

syntax used by open router, the end of the model name is really critical to see when streaming or scanning the last

If you are going to publicly write about it without reporting it then that would be a security issue. If you don't end up reporting it then you should not publicly write about it.

RobbBoss•3/14/25, 10:03 PM

No, if I write about it I'll probably share it with researcher friends. I'm not going to randomly publicly disclose security issues.

Thank you for the due diligence in stating that.

I also have no interest in joining HackerOne, tbh. But I respect that there's a community of people that find bugs and there are bounties and all this. I have no interest in bounties at all. I would take this to #off-topic but I gather that this is probably the end of this thread.

Isaac McFadyen•3/14/25, 10:26 PM

It's less about bounties (although that's part of it) and more about responsible disclosure. By telling others that aren't Cloudflare, you risk them telling others themselves and eventually telling someone who is in a position to and wants to actively exploit it.

I would heavily encourage you to share through HackerOne, but if you don't want to I'd avoid sharing with anyone else regardless of whether they are friends or not.

I have a product idea. An AI Router. Similar to AI Gateway but it would allow me to define custom routes where I can define the target llm model and settings like temp, max_tokens etc. I would then route each app llm call to the custome AI Router endpoint. I would send only the prompts (system(optional) and user prompts). All other settings, like which llm to use, requst settings would be defined at AI router level. With one setting I can turn on AI Gateway on the router.

This would allow me to quickly adapt to the fast paced landscape of llm models. I can quickly reconfigure app's functionality to use different llm's and even run tests to quickly to validate outputs.

I'm wasting a lot of time updating and refactoring app code to stay up to date with llm models. Each time I need to:

find the llm api functionality. Try to remember what it does and understand it
refactor the code to use different model because i found a better one, cheaper one or the one im using will no longer available.
test in staging, test in production

I think there is a huge opportunity here for a cloud provider to own this pipeline. A great lock in for the customer as well. Please pass the idea to your product team to further explore. Thanks!

Hi! I’d like to use AI Gateway as a proxy for my Replicate model.

I see Replicate listed as a supported provider, and the docs mention it's “supported out of the box.” However, I don’t see any configuration options to route requests to Replicate — and in the “Connect to your applications with API Endpoints” popup, Replicate isn’t listed among the AI Platforms.

Is it currently possible to use AI Gateway as a proxy for Replicate? If so, how can I set that up?
