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).

explain more what you meant by your last sentence on context caching? initially i thought that was re: semantic caching, but seems you're talking about something different

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).

thanks for sharing so the ask here is for ai gateway to support tracking the costs of context caching through providers, including google

what does the response look like from google when using conext caching? Curious to see how it splits out input, output, and context caching because that is how we would track tokens to then calculate

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?

ItsWendell•5/10/25, 1:42 PM

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.

I am unsure if this is the best place for a bug report... AI Gateway openai comptable for workers-ai (https://developers.cloudflare.com/ai-gateway/providers/workersai/#openai-compatible-endpoints) isn't working properly when sending an image to llama4 (https://developers.cloudflare.com/workers-ai/models/llama-4-scout-17b-16e-instruct/) while if using AI Gateway + Direct model call (@cf/meta/llama-4-scout-17b-16e-instruct) it will work.

Nico•6/4/25, 12:19 AM

I'm trying out the new OpenAI-compatible endpoint and running into a weird difference between using the OpenAI SDK and curl. I've tested the exact code from the docs for both methods and curl works but the typescript example does not.

Here's the typescript:

import OpenAI from "openai";

const client = new OpenAI({
    apiKey: process.env.GEMINI_API_KEY,
    baseURL: "<my gateway url>"
});

const response = await client.chat.completions.create({
    model: "google-ai-studio/gemini-2.0-flash",
    messages: [{ role: "user", content: "What is Cloudflare?" }],
});

console.log(response.choices[0]?.message.content);

import OpenAI from "openai";

const client = new OpenAI({
    apiKey: process.env.GEMINI_API_KEY,
    baseURL: "<my gateway url>"
});

const response = await client.chat.completions.create({
    model: "google-ai-studio/gemini-2.0-flash",
    messages: [{ role: "user", content: "What is Cloudflare?" }],
});

console.log(response.choices[0]?.message.content);

import OpenAI from "openai";

const client = new OpenAI({
    apiKey: process.env.GEMINI_API_KEY,
    baseURL: "<my gateway url>"
});

const response = await client.chat.completions.create({
    model: "google-ai-studio/gemini-2.0-flash",
    messages: [{ role: "user", content: "What is Cloudflare?" }],
});

console.log(response.choices[0]?.message.content);

import OpenAI from "openai";

const client = new OpenAI({

    baseURL: "<my gateway url>"
});

const response = await client.chat.completions.create({
    model: "google-ai-studio/gemini-2.0-flash",
    messages: [{ role: "user", content: "What is Cloudflare?" }],
});

console.log(response.choices[0]?.message.content);
