Yes. It's not implemented in the package. I created a quick fix (https://github.com/Raylight-PWL/workers-ai-provider/pull/1) but haven't used/tested the package. In any case, you can look at the diff if you want to patch it yourself.

do you plan to add more embedding models?
only having a single not multi lingual model available for embedding is kind of a big blocker to use workers ai

beingmudit [WePlayDOS]•2/12/25, 9:08 PM

Hi CF team, had a doubt about function calling and the supported model. I can see that only one model is supported but in the documentation of this llama model - https://developers.cloudflare.com/workers-ai/models/llama-3.2-11b-vision-instruct/

I can see in the input/output params, we can pass tools. Is there a documentation mismatch?

blindChicken•2/13/25, 8:58 PM

I think the error may be caused because you did not provide a description for your properties.
You have:

"properties": {
  "model": {
    "type": "string"
  },
  ...

"properties": {
  "model": {
    "type": "string"
  },
  ...

"properties": {
  "model": {
    "type": "string"
  },
  ...

"properties": {
  "model": {
    "type": "string"
  },
  ...

This should be:

"properties": {
  "model": {
    "type": "string",
    "description": "name of the model to be used" //or whatever the appropriate description is
  },
  ...

"properties": {
  "model": {
    "type": "string",
    "description": "name of the model to be used" //or whatever the appropriate description is
  },
  ...

"properties": {
  "model": {
    "type": "string",
    "description": "name of the model to be used" //or whatever the appropriate description is
  },
  ...

"properties": {
  "model": {
    "type": "string",
    "description": "name of the model to be used" //or whatever the appropriate description is
  },
  ...

And this should be repeated for each of your props.

Hey! our AI requests are failing with the following rate limit error, while the volume is relatively low ($20 of consumption). That heavily impacts our services

 {       message: 'AiError: AiError: Capacity temporarily exceeded, please try again.',       code: 3040     }

 {       message: 'AiError: AiError: Capacity temporarily exceeded, please try again.',       code: 3040     }

I was getting the same error, but according to my dashboard I was no where close to the my limit. I think the error is not specific to any one account but may be that the network is overloaded. (I'm speculating) I waited a few minutes and I was able to continue normally.

IDK about enforcement, but it is needed so that the model can assign the proper value to the proper properties. Since all this AI stuff is probabilistic it is possible that it can work without the description, and then just as easily not work.

Bbeingmudit [WePlayDOS]CF team, can anyone help with yhe above?

only 1 ancient model on CF support Func Calling, even when your payload works, it would return something poor-quality and irrelevant, that's my experience

I agree it sucks, and it would be nice if someone from Cloudflare could chime in a clarify exactly what the error really is:

{ message: 'AiError: AiError: Capacity temporarily exceeded, please try again.', code: 3040 }

{ message: 'AiError: AiError: Capacity temporarily exceeded, please try again.', code: 3040 }

Sry is i missunderstand, but i am RN on the free plan, using my 10.000 AI Neurons a day and ran into a problem

The LLM response seems to be arbitrarily cut off at 500 tokens.
is there such a policy? is there a way to disable this or is it just a code issue on my part?

Has anyone tried tool calling with

Deepseek-R1

Deepseek-R1

? When I tried it,the model simply returns a normal response as if tools where not specified. I used the schema that works

Hermes

and

LLama

LLama

, and I have also tried the schema shown here: https://api-docs.deepseek.com/guides/function_calling. But neither work.
