Too many providers for you to add,but most of them are OpenAI-Compatible-Endpoints, I am thinking if you can add a feature to let us input the API base that we want ai gateway request.

just like litellm or porkey and other ai gateway products do.

for custom costs, does it able to take cache hit/miss into consideration? otherwise is it possible for me to calculate a final cost and pass it? for example, I can get the request cost from OpenRouter directly and would like to have it recorded

For our use-case it would be enough to enable the guardrails on the embedding step before RAG. We don't need to run them afterwards.

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/

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.

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.

Yeah, two Gateways would work, but a bit annoying to set up 2 more gateways (prod and dev) and share the config around.

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

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

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
