Subject: Grok API Location Detection Issue When Using ai-gateway from Mainland China

Description:

Hello Cloudflare team,

I am a developer based in Mainland China. I am currently using ai-gateway to call the Grok API. I have noticed that when I make requests directly (without a VPN) from my local developing Mac, Grok is able to detect my actual location and refuse my request. However, when I use a VPN to make the same Grok API calls, this location detection issue does not occur.

Could you please help me understand why Grok is able to recognize my real location when I am not using a VPN, and whether there are any configuration options or best practices to prevent this? Is this expected behavior for users in Mainland China, or is there something specific to ai-gateway or my setup that I should be aware of?

Thank you for your assistance!

I have an app where users add their own OpenAI api key. So the Auth header will be different from user to user.

Can I still use

ai-gateway

ai-gateway

ai-gateway

ai-gateway or cache will get mixed up?

abuiles•4/19/25, 1:38 AM

Minor nit, but it seems like the logs filter UI is assuming strings in the metadata.

The example in the docs shows this

--header 'cf-aig-metadata: {"team": "AI", "user": 12345, "test":true}' \

--header 'cf-aig-metadata: {"team": "AI", "user": 12345, "test":true}' \

--header 'cf-aig-metadata: {"team": "AI", "user": 12345, "test":true}' \

--header 'cf-aig-metadata: {"team": "AI", "user": 12345, "test":true}' \

But then when you try to filter in the UI it won't work

filters: [{"key":"metadata.value","operator":"eq","value":["12345"]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

filters: [{"key":"metadata.value","operator":"eq","value":["12345"]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

filters: [{"key":"metadata.value","operator":"eq","value":["12345"]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

filters: [{"key":"metadata.value","operator":"eq","value":["12345"]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

I changed the request manually to a a number and it worked

filters: [{"key":"metadata.value","operator":"eq","value":[12345]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

filters: [{"key":"metadata.value","operator":"eq","value":[12345]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

filters: [{"key":"metadata.value","operator":"eq","value":[12345]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

filters: [{"key":"metadata.value","operator":"eq","value":[12345]},{"key":"metadata.key","operator":"eq","value":["user"]},{"key":"created_at","operator":"gt","value":["2025-04-18T01:21:00.000Z"]}]

Is this expected?

Cloudflare AI Gateway has a 100-second origin timeout. But when using inference models like Gemini 2.5 Pro without streaming output, it's easy to exceed that 100-second limit.

This results in an HTTP 524 error, which is a real headache.

Hi everyone,

I'm wondering if there are plans to support cost estimation for streaming requests in AI Gateway?

We're looking at AI Gateway + Logpush for our SaaS application where we need to track costs across different tenants. Currently, we're using various models from different AI providers, and managing cost tracking has become quite messy.

AI Gateway looks really promising for our use case, but we specifically need to understand how streaming requests would be handled in terms of cost estimation.

Is there a public roadmap available that might indicate when this feature could be expected? Or any information about the development timeline for streaming request cost tracking?

ItsWendell•4/22/25, 10:01 PM

I've been running into the same problem, I think the 100-second limit also applies for outgoing requests from workers, whether you use AI Gateway or not.

I also did long thinking, non- streaming requests with high output token limits to the Gemini 2.5 APIs where I ran into this problem quite often. I needed to use JSON / structured outputs.

I wrote my engine to use streaming text endpoints. I prompt engineered it in a way where it streams occasional [markers] for real time updates I needed and for structured output I needed for the request, which honestly have been working quite well. It prevents the 100 seconds proxy timeout since the streams start before that time, meanwhile I can comfortably stream up to 40/50k tokens like this using 1 API call.

I also built in some fault tolerance and output recovery, by occasionally storing the output during streaming into KV (Durable Objects storage is also a possibility). If it fails midway and retries in my workflow, it attempts to restore the state and resume where it left off.

What I really like is that I can send real-time updates this way to consumers, since I prompted Gemini to occasionally send an [status: {...}] marker which I can parse in real-time, since outputting 40/50k tokens can time some time.

if requests are not going through AI Gateway, you might need to increase this limit for your domain. Looks like it may be an enterprise only capability https://developers.cloudflare.com/fundamentals/reference/connection-limits/#between-cloudflare-and-origin-server

When HTTP/HTTPS traffic is proxied through Cloudflare, there are often two established TCP connections: the first is between the requesting client to Cloudflare and the second is between Cloudflare and the origin server.

Thanks for coming back to this! I was aware of the limits and the ability of getting an enterprise plan to upgrade these limits, but that would be for our business in an MVP / prototyping phase not feasable.

If context caching would be supported in AI Gateway, that would be great since than we could also use features like tracking costs of that (in google's case it returns usage, unsure if other providers offer similar methods).

I

ItsWendell•4/24/25, 5:02 PM

@Kathy | Browser Rendering PM Ah fair, it's related to "context caching" at Google / Vertex AI. For huge contexts and long repeated runs with the same context this can siginificantly speed up inference and cost savings. https://ai.google.dev/gemini-api/docs/caching?lang=rest.

The problem I'm having here is that Google is taking an increasingly long time to more context you give it to create this Context Cache. We often hit 2+ minutes for bigger context (20/30+ PDF files, some of them 100+ pages, which on their side I think are being transformed into images, and then into tokens).

Hey!

I'm currently checking AI Gateway for the company I work at — mainly to track token usage per our customer.

While testing GPT-4.1 with streaming enabled, I noticed that if a client cancels a request mid-stream, there’s no trace of that request in the AI Gateway logs.
Is this the intended behavior, or could this be a bug or a limitation of the current implementation?

None of the newer gemini models (2.5 Flash / Pro) and even 2.0 Flash (and 2.0 Flash Lite) properly track input / output tokens. We started sending metadata and pricing information into the AI Gateway, but just realized that tokens are not tracked and we don't have control over that.

Google does provide in both streaming and non-streaming use-cases the used tokens in detail, also visible in the output json of AI Gateway.
