I'm not sure if R1 works well with tools at all, based on what I've heard. But the missing opening <think> is probably a bug, I can't imagine it's intended.

Flux Schnell model still doesn't have a random seed implementation and image sizes (width x height), unlike Stable Diffusion models. When is this going to be implemented, if possible?

Has there been a change to the

hermes-2-pro-mistral-7b

hermes-2-pro-mistral-7b

hermes-2-pro-mistral-7b

hermes-2-pro-mistral-7b model. I have a very basic app based on CF's function calling tutorial. I made the app about a month ago and has been working fine since. But over the past few days it has stopped working and it appears that the model has changed the format of its response. Here is how it is responding now:

User Prompt: show me the color of an avocado?
AI result is: {
  response: '<tool_call>\n' +
    "{'arguments': {'r': 69, 'g': 139, 'b': 69}, 'name': 'switchLightColor'}\n" +

    '\n' +
    'I have chosen a color that represents an avocado. The color of an avocado is typically a pale green with a hint of creaminess.

  usage: { prompt_tokens: 0, completion_tokens: 0, total_tokens: 0 }
}

}

}

The tool call is being returned within the response and is correctly tagged with

<tool_call>

<tool_call>

but the response no longer returns a

tool_calls

tool_calls

prop, so my code isn't calling anything it only shows the malformed response.

my pillow fixed my issue:

raw data for simplicity and efficiency in handling large images, this method may lead to more API calls if the image is re-generated each time it's accessed (Caching handles that last part.)

base64 encoding to minimize API calls over performance (Easier to implement)

Raw data + cache is the only way to go

Raylight•3/22/25, 6:59 AM

As James implied, it would be easier to help if you have a snippet showing the call to the model, but in general: The docs show the same set of parameters (e.g.

image

image

image

image,

mask

mask

mask

mask) for several models, but the only model that does inpainting is

@cf/runwayml/stable-diffusion-v1-5-inpainting

@cf/runwayml/stable-diffusion-v1-5-inpainting

@cf/runwayml/stable-diffusion-v1-5-inpainting

@cf/runwayml/stable-diffusion-v1-5-inpainting.
Make sure to supply both

image

image

image

image and

mask

mask

mask

mask when calling it. The format is

mask: [...new Uint8Array(await maskImage.arrayBuffer())]

mask: [...new Uint8Array(await maskImage.arrayBuffer())]

mask: [...new Uint8Array(await maskImage.arrayBuffer())]

mask: [...new Uint8Array(await maskImage.arrayBuffer())], where

maskImage

maskImage

maskImage

maskImage could be the result of e.g.

await fetch(/* mask image url */)

await fetch(/* mask image url */)

await fetch(/* mask image url */)

await fetch(/* mask image url */).

missing the opening <think> tag

This is due to a quirk in the prompt template, which forces the <think> tag in order to require the model to think through it's response, but which results in this behavior

I think I have found a bug with Cloudflare's Worker Ai

I'm basically making a super simple Stable Diffusion wrapper with Pages and Worker Ai. While making the UI and testing it, I probably made 50 - 80
50 - 80
50 - 80
50 - 80 images with it. But my Daily Neurons Limits is still 0
0
0
0 (as in nothing used)

So, I checked the Pricing and found no mention of Stable Diffusion's neuron pricing.

Could it be they forgot to consider these model to add to the daily usage limit?
OR is 80
80
80
80 images too low to be show in the dashboard?

is there no sample worker code for this for something basic like r2 audio file to transcribe ?

I am using a worker to send it to 3rd party api to transcribe using queue

But I would like use worker ai whisper turbo as a failover. Without over engineering or breaking my webapp.

Do I just implement a new queue instead of a separate worker?

Perhaps eventually cf workflow but for now I don’t want to break my current webapp by reengineering anything too much.

Just want to do backup for the rare times 3rd api fails.

Currently stream APIs (including official API and OpenAI compatible API) do not properly handle tool_call response; the tool call content is embedded in the

response

or

content

content

content

content field.
Could the stream API provide the same behavior as the non-stream API? For example,

"response“: null, "tool_calls": [...]

"response“: null, "tool_calls": [...]

"response“: null, "tool_calls": [...]

"response“: null, "tool_calls": [...]
