do i need to send the assistant querying the tool as part of the message history?

DrWayne•7/29/25, 7:25 PM

I'm having trouble with the https://api.cloudflare.com/client/v4/accounts/{accountId}/ai/models/search endpoint in-browser. The fetch triggers an OPTIONS request that fails with "400 Bad Request".
The GET request works just fine via curl on the command line, and the OPTIONS request curl returns

{"success":false,"errors":[{"code":9106,"message":"Missing X-Auth-Key, X-Auth-Email or Authorization headers"}]}

{"success":false,"errors":[{"code":9106,"message":"Missing X-Auth-Key, X-Auth-Email or Authorization headers"}]}

Since the OPTIONS call is checking whether the endpoint allows those headers, it will never include them in the request. I'm betting it is just an overzealous config on needing the auth header/s missing an exception for the OPTIONS call. Or am I missing something here?

Yes, both the tool result and the tool call need to be included as a message.

Isaac McFadyen•7/29/25, 7:38 PM

Also it looks like you have the messages array backwards. Lower in the array (higher index) is more recent.

Isaac McFadyen•7/29/25, 7:38 PM

I.e. system, then user, then assistant tool call, then tool result.

zsueoOP•7/29/25, 7:38 PM

huh the example had it higher in the array as first, easier for me to manage

IIsaac McFadyen Yes, both the tool result and the tool call need to be included as a message.

zsueoOP•7/29/25, 7:39 PM

the input schema for this model doesnt have anything like that i guess the docs are a bit behind

Zzsueo huh the example had it higher in the array as first, easier for me to manage

Yeah, so the

oh right myb i got it mixed up

IIsaac McFadyen Yes, both the tool result and the tool call need to be included as a message.

zsueoOP•7/29/25, 7:42 PM

is there a recommended schema for this?

zsueoOP•7/29/25, 7:42 PM

i cant find anything on cloudflares docs

Isaac McFadyen•7/29/25, 7:45 PM

I'm not 100% sure, but I expect it mirrors the OpenAI schema, so it would be an assistant message but with

tool_calls

tool_calls

instead of string

content

zsueoOP•7/30/25, 6:02 PM

hey im noticing that sometimes the ai does not call the tool properly leading to json just floating in the reply, what is the expected format the ai is supposed to output in so i can try and force that?

ed•7/30/25, 7:54 PM

when's the next models update? would love to have kimi-k2, GLM, etc

apparently maybe K2 soon

i kindly pray by my bedside that we support

in cloudflare workers ai.

would acc be so insane.

im using it for my current embeddings and i don't think its best practice to use 2 different embedding models, as I see we only support bge.

Shadi•8/1/25, 4:35 PM

lmao

can anyone say how can we change the embdding model in autorag?
and also does autorag support multilanguae?

Hi Cloudflare team,

Does the workers ai @cf/openai/gpt-oss-120b model support structured outputs with JSON schemas?

I need to force the model to return responses in a specific JSON format using response_format parameter. I don't see this mentioned in the docs.

Chaika•8/6/25, 6:19 PM

They're using the new responses openai format:
https://platform.openai.com/docs/api-reference/responses/create

which supports that under the text object looks like. Tested it quickly and it seems to work fine for me

will gpt-oss-120b support stream ?

Chaika•8/7/25, 3:37 PM

It already does support streaming via openai's new response format streaming:
https://platform.openai.com/docs/guides/streaming-responses?api-mode=responses

akazwz•8/7/25, 5:00 PM

I was using the response api. without stream param, it works, with stream: true, server error, return 500

Chaika•8/7/25, 5:20 PM

Have to use Workers binding for streaming

Chaika•8/7/25, 5:23 PM

I don't think the direct api has supported streaming for any model? Not 100% sure as I don't use the api myself, but yea that same request via binding streaming looks fine

Dev2xl•8/9/25, 10:35 PM

Hello,
I’m exploring options for running inference on private TensorFlow models with Cloudflare’s products. Is it possible to achieve this using Workers or any other Cloudflare service? Any technical guidance or references would be greatly appreciated. Thank you!

Isaac McFadyen•8/10/25, 4:16 PM

You could try Containers but they're currently ill-suited for most ML things as they have fairly low resource allocation and no GPUs.

ixixix•8/12/25, 6:44 AM

I know the docs don't mention it, but just to confirm, the /audio/transcriptions endpoint isn't supported as an openai compatible endpoint in Workers AI or AI Gateway for the cloudflare whisper models, right? I'm getting

{"errors":[{"code":7000,"message":"No route for that URI"}]}

{"errors":[{"code":7000,"message":"No route for that URI"}]}

and

{"code":2002,"message":"Internal server error"}

{"code":2002,"message":"Internal server error"}

tomerzcod•8/13/25, 7:29 AM

Hey, i've been following the cloudflare docs, I have a worker with ai bindings set I'm logged in but whatever i do I get the 10000: authentication error.

What am I missing? can't find any info how to fix this

Hi, does anyone happen to know when the Chat Completions API will come to the gpt-oss models?

Bryan•8/15/25, 4:38 AM

Does anyone have advice for getting worker-ai function calling models to work with traditional tool calls, while using the open-ai compatibility layer *and * streaming?
I can't get any model to both send back tool recommendations in the correct format and summarize a tool call.

Mistral keeps recommending tools via XML in regular text content, but when given a chat history where the most recent message is a tool execution, it will correctly summarize the tool execution.
llama-4-scout will correctly recommended a tool, but when given a chat history where the most recent message is a tool execution, it will recommend the tool again instead of summarizing.
The other 2 function calling models aren't any better.

If i turn off streaming, Mistral at least works correctly, but streaming is strongly preferred.

Does anyone know what I'm missing?

AAhmed is there a way to get sparse embeddings from `@cf/baai/bge-m3`

Nipsuli•8/15/25, 11:15 PM

openai model dont work with chat/completion API, that can be fixed? from model change standpoint it's good to have the option to switch only changing the string name of the model

Heya pretty people! Im looking for a way to set a 'spending limit' on my worker ai usage. Does that exist ?

How to use the current image generation models that CF offers? So far in my tests I have good results with https://developers.cloudflare.com/workers-ai/models/flux-1-schnell/. However there is no dimension control which renders it pretty much unusable for what I want to offer. Then I dont see any other upscaling models available either unfortunately.

Is there any AI model available that has internet access and could search for realtime/live data? I don't think so, couldn't find one, but asking just in case
