portkey is much faster but usually latency is constrained by the LLM not the gateway

hm so you would not want to run on the prompts where you're querying RAG? (this "knowledge query" part of RAG https://developers.cloudflare.com/reference-architecture/diagrams/ai/ai-rag/#knowledge-queries

For embeddings, we only evaluate the prompts https://developers.cloudflare.com/ai-gateway/guardrails/supported-model-types/

if it's a cache HIT the cost will be 0. Even if you have passed a custom cost

Is there a way to use AI gateway for models that are not supported? I’m thinking of image models API where it would be cool to have the request go through the AI gateway to log requests/costs/analytics…
In particular I’m thinking of something kind of universal where we just prepend the full endpoint with our gateway url and inject correct headers.

by cache hit, I mean the one on anthropic, not the one on CF https://docs.anthropic.com/en/docs/build-with-claude/prompt-caching

J

Johnny Bernhard•3/4/25, 3:24 PM

Yes. It's a super simple flow of:
Embed query and retrieve from Vector Store
Build a big prompt with query + RAG results
Send that to LLM

There is no need to double guardrail it. The prompt is already checked in the embedding step.
And the big query is build from safe-bits (guard before entrying into DB + guarded user query).

So the second guard is just extra latency.

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?

Yeah, two Gateways would work, but a bit annoying to set up 2 more gateways (prod and dev) and share the config around.
But definitely understand this not being too important to change right now.

please inplement ratelimit per user/metadata.... that would be awsome!

Super Morris•3/8/25, 4:52 PM

that would help everybody building apps with ai that want to rate limit their users usage out of the box.

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}

{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

Please do not post your question in multiple channels/post it multiple times per the rules at #

welcome-and-rules. It creates confusion for people trying to help you and doesn't get your issue or question solved any faster.

disabling and re-enabling will not clear it's previous cache, sorry

Right now the only option is to wait for the ttl to expire --> we need to add the ability to purge cache still

This is super interesting. Thank you for sharing that. From this, and based on the JSON output that was shared... well, I just devised another possible attack which might reveal the encryption keys themselves. It's possible this mitigation technique might create a compromise in its current implementation. Given that discussing it here would be irresponsible, who should I contact, please?

If you believe you've found a vulnerability you should report it through HackerOne.

SuperHelpflare•3/14/25, 8:55 PM

This discord is not for for reporting security reports. Cloudflare has a Responsible Disclosure program run through HackerOne where you can privately file reports, which will be reviewed by the appropriate teams and for which you may be eligible for bug bounties: https://hackerone.com/cloudflare

Cloudflare Public Bug Bounty - Bug Bounty Program | HackerOne

The Cloudflare Public Bug Bounty Bug Bounty Program enlists the help of the hacker community at HackerOne to make Cloudflare Public Bug Bounty more secure. HackerOne is the #1 hacker-powered security platform, helping organizations find and fix critical vulnerabilities before they can be criminally exploited.

Thanks, I juuust saw that at the end of the article. haha Thank you for responding, though, truly.

I am likely to write about it, but not likely to go through the trouble of proving it out, which seems necessary to report it there. Well, thank you for that insight, regardless!

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.

R

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.

R

RobbBoss•3/14/25, 10:03 PM

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!

Sunday night project drop! Built a Cloudflare AI Gateway Provider for the Vercel AI SDK

Unlike other gateway products (e.g., Portkey), this one lets you keep using the official providers, so you still get all the type hints!

Try it out: npm install ai-gateway-provider

I configured an AI gateway for the openrouter, but why does it always additionally call the @cf large language model when using the conversation feature?
