Hi,

I’m encountering an issue with

Ai-Search (Auto RAG)

Ai-Search (Auto RAG)

Ai-Search (Auto RAG)

Ai-Search (Auto RAG) with folder-based filtering using the

gt

gt

gt

gt,

gte

gte

gte

gte, and

eq

eq

eq

eq filter types. Filtering works as expected when targeting a top-level folder, but fails when specifying a sub-folder.

Below is an example payload that works and returns all files inside

customer-a

customer-a

customer-a

customer-a as well as its sub-folders:

{
  "query": "Cat",
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a//"
  }
}

{
  "query": "Cat",
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a//"
  }
}

{
  "query": "Cat",
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a//"
  }
}

{
  "query": "Cat",
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a//"
  }
}

However, the following payloads do not return any results, although the specified sub-folder exists:

{
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gt",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "eq",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "eq",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "eq",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "eq",
    "key": "folder",
    "value": "customer-a/sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder//"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder//"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder//"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a/sub-folder//"
  }
}

The following variant does work, but only returns items from the folder itself — not from its deeper sub-folders:

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a//sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a//sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a//sub-folder"
  }
}

{
  "filters": {
    "type": "gte",
    "key": "folder",
    "value": "customer-a//sub-folder"
  }
}

What I need

I would like to search inside a specific sub-folder, ideally including its nested sub-folders, similar to how filtering works for the top-level folder.

Could you please advise on the correct filtering method or confirm whether this is a known limitation or bug?

Thank you in advance for your assistance.

Hi! Thanks for the replies
I have one follow-up question:

I want to upload the whole PDF file directly to the AI model and get back a clean, readable JSON — without having to parse the PDF myself first.

Basically:
No pre-processing
No pdf-parse / PDF.js / external extraction
Just: Upload PDF → AI extracts → returns structured output

Is there a recommended Cloudflare AI model / workflow that already supports this type of direct PDF→JSON parsing?
A model similar to “document AI” (like Google’s), where you upload a PDF and get structured data back?

Thanks again!

I am trying to use Flux Schnell text to image model from my worker and I am encountering censorship, not only that but I get censorship errors even when I didn't enter anything spicy in the prompts like just the word "Elephant" triggers:

"AiError: Input prompt contains NSFW content."

and the other thing is, what does this model accept 2 params (prompt and steps)? its unusable since I can't even ask for a specific size.

Any way to disable the NSFW filter and accept more params?

Are you using workers typescript binding? I do that, and readable stream output gets me only one 41 byte chunk stating network connection lost. This happens when I apply stream flag.

Are you doing the same and you get streaming chunks fine?

On another topic regarding usage storage and logging.

My understanding is that workers ai do NOT store any data or logs for inputs and outputs of any of the models involved.

Of course, I’m talking about direct workers AI no gateways etc.

I’m referring to this section of https://developers.cloudflare.com/workers-ai/platform/data-usage/

Your Customer Content for Workers AI may be stored by Cloudflare if you specifically use a storage service (e.g., R2, KV, DO, Vectorize, etc.) in conjunction with Workers AI.

Would that be correct?

Cloudflare Docs

Data usage

Cloudflare processes certain customer data in order to provide the Workers AI service, subject to our Privacy Policy and Self-Serve Subscription Agreement or Enterprise Subscription Agreement (as applicable).

npx wrangler login

npx wrangler login or

to be clear, i don’t think that’s intended to work that way, so there’s probably something wrong with my setup that causes that behavior.

captain•12/3/25, 10:23 PM

been reviewing the new flux 2, and comparing using on workers vs fal.ai, i would rather just use it in workers to make things less complex. However it seems like using it on fal.ai if i campare the demo promt in the workers docs: 16 steps + 1024x1024. That demo would be half the price on fal, does anybody know if i am calculating this incorrectly or if i am not properly understanding the value of the worker request. I am typically used to cloudflare costs being lower but in this case it doesn't seem so

Reux•12/8/25, 6:50 PM

I've been using Flux 2 Dev, and there honestly seems to be a serious issue with the filter for prompts and input images, there are way too many false positives, It's flagging completely legitimate images and prompts that are the exact opposite of inappropriate. The false positives are so frequent that it's impossible to use the model in a real-world application, please take a look at the filter

What is the correct page to see the pricings?

Take @cf/google/embeddinggemma-300m:

The model page says nothing: https://developers.cloudflare.com/workers-ai/models/embeddinggemma-300m/
The workers ai platform page also says nothing: https://developers.cloudflare.com/workers-ai/platform/pricing/
But then the models overview that doesn't have descriptions, shown a neuron price, but unlike other models no price per million in USD: https://dash.cloudflare.com/123456/ai/workers-ai/models

Does this mean the model can only be used via neurons? Or is this a documenation issue?
