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

Isaac McFadyen•7/29/25, 7:41 PM

Yeah, so the unshiftunshift adds the system message to the start of the array

zsueoOP•7/29/25, 7:42 PM

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_callstool_calls instead of string contentcontent: https://platform.openai.com/docs/api-reference/chat/create

Isaac McFadyen•7/29/25, 7:45 PM

Worth a try, if it's wrong you'll get an error that might help troubleshoot further

zsueoOP•7/29/25, 7:46 PM

thanks so much!

zsueoOP•7/29/25, 9:02 PM

it worked!! just incase anyone wants to do something similar this is the schema i used

    }

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

rob•7/31/25, 6:16 PM

apparently maybe K2 soon

i kindly pray by my bedside that we support allminiLmv6allminiLmv6 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

R3AP3R editz•8/3/25, 3:06 PM

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

𝗞enneth•8/6/25, 6:22 PM

thanks @Chaika

akazwz•8/7/25, 10:26 AM

will gpt-oss-120b support stream ?

Aakazwz 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

xugik•8/14/25, 11:51 AM

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

yeah, this would be nice

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

DonJonko•8/19/25, 3:49 PM

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

MichaelC•8/20/25, 11:29 AM

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.

Not really, Workers AI is more low-level and if you wanted an LLM to do this you'd need to orchestrate yourself or use Sandboxes: https://developers.cloudflare.com/changelog/2025-06-24-announcing-sandboxes/
