i think this is what your looking for, https://developers.cloudflare.com/workers-ai/features/json-mode/

Cloudflare Docs

When we want text-generation AI models to interact with databases, services, and external systems programmatically, typically when using tool calling or building AI agents, we must have structured response formats rather than natural language.

found this, assuming these limist for AutoRag https://developers.cloudflare.com/autorag/configuration/data-source/

Data source · AutoRAG

AutoRAG currently supports Cloudflare R2 as the data source for storing your knowledge base. To get started, configure an R2 bucket containing your data.

mongj•4/9/25, 7:23 PM

will the whisper model on workers ai eventually support auto language detection? we would like to move from openai to workers ai but the lack of language detection is the biggest blocker right now

M

mongj•4/9/25, 7:30 PM

it's certainly possible to put a language detection model in front, but that defeats the cost and latency benefit from using the serverless models on workers ai, especially since other whisper providers (openai, fireworks, groq) already provides it

Markdown Conversion · Cloudflare Workers AI docs

Markdown is essential for text generation and large language models (LLMs) in training and inference because it can provide structured, semantic, human, and machine-readable input. Likewise, Markdown facilitates chunking and structuring input data for better retrieval and synthesis in the context of RAGs, and its simplicity and ease of parsing a...

Hiya, I'm trying to understand waht should I use, my case is as follow:

I have an API that receives X amount of parameters, I want the user to be able to write "buy me X with Y value and then do Z actions", I'm basically looking for a way for an AI to interept that and return a json like {param1: x, param2: y, param3:z}.

What should I use for that?

{"code":10000,"message":"Authentication error"}

{"code":10000,"message":"Authentication error"} in the REST response, but do get

hello y'all, is there anybody who is using AI SDK with Cloudflare Workers AI provider or anybody who is working on the provider atm?

I was surprised when I saw that image-part is not implemented on the provider, so I was wondering if I should implement it and make a PR or is there anything to be discussed first?

Apologies if this is a bit off topic but I figured someone in here would know the answer. My current solution is just to use lambda on AWS with ffmpeg but if there's an easy way to do this on CF I'd love to hear about it.

Already tried that but it seams that the mistral model is not capable of analyzing images even it‘s possible to provide one?

Using the following request:

const aiResponse = await env.AI.run(
"@cf/mistralai/mistral-small-3.1-24b-instruct",
{
messages: [
{
role: 'system',
content: "You are a helpful assistant that analyzes images."
},
{
role: "user",
content: [
{
type: "image_url",
image_url: {
url: images[0],
}
},
{
type: "text",
text: prompt
}
]
}
]
}
);

I'm sorry, but I can't directly analyze images or videos.
