ToriannaOP•3/14/25, 10:50 AM

Those repackage your image into a smaller file, while keeping about the same quality

ToriannaOP•3/14/25, 10:52 AM

Now if you want to compress inside Workers, that's a little bit more tricky, but you can look up Cloudflare Images. You get free (I think) image transformations so long as you don't store images there

karenr•3/14/25, 10:57 AM

Yeah, this is what I actually did. was wondering if using AI for compression is a better choice. Thanks @Torianna

ToriannaOP•3/14/25, 10:57 AM

I don't think there's any public models

ToriannaOP•3/14/25, 10:58 AM

I know Google is working on one, but that's internal

karenr•3/14/25, 11:01 AM

Google - oh really?
yeah.. current models are multimodal AI model with both vision and language capabilities not specific to compression

TTorianna I don't think there's any public models

Isaac McFadyen•3/14/25, 3:24 PM

Nvidia has one and it's teeeechnically public but not really? i.e. it's integrated into their new Neural Shader stuff but I don't believe the model is open-weight.

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.

JoaoCupido•3/14/25, 7:45 PM

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?

blindChicken•3/16/25, 5:58 PM

Has there been a change to the

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" +
    '</tool_call>\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. To represent this, I have selected a color with a higher green value (139) and balanced amounts of red (69) and blue (69) values. This creates a color that is reminiscent of the natural hue of an avocado, bringing the essence of the fruit into the room.',
  usage: { prompt_tokens: 0, completion_tokens: 0, total_tokens: 0 }
}

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" +
    '</tool_call>\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.

This creates a color that is reminiscent of the natural hue of an avocado, bringing the essence of the fruit into the room.',
  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.

blindChicken•3/16/25, 6:11 PM

If I replace

hermes-2-pro-mistral-7b

hermes-2-pro-mistral-7b

with

@cf/meta/llama-3.3-70b-instruct-fp8-fast

@cf/meta/llama-3.3-70b-instruct-fp8-fast

then it works fine. Something must have changed with the Mistral model

Seems like all the models on Workers AI have such small Context WIndows, is there any that will be added that come closer to Google Gemini?

si(dot).xth•3/20/25, 11:30 AM

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

JJMPA hello, is inpaiting ai workers working currently?

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

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

.
Make sure to supply both

image

image

and

mask

mask

when calling it. The format is

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

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

, where

maskImage

maskImage

could be the result of e.g.

await fetch(/* mask image url */)

await fetch(/* mask image url */)

Silvan•3/23/25, 11:09 AM

I really hope we get some “better” text generation models on here soon. i tried every single one for story creation and nothing came even remotely close to claude atm.

ochrons•3/23/25, 3:37 PM

I'm using

@cf/openai/whisper-large-v3-turbo

@cf/openai/whisper-large-v3-turbo

to convert audio into text. It works fine when recording on Pixel 9 in AAC format, but fails when recording on an older Oneplus 7T with AAC (I'm using Flutter to build the app). Using an AMR WB format works fine, though. Also all the AAC formats work fine when given to Google Gemini Flash/Pro models

ochrons•3/23/25, 3:38 PM

I tried both

MPEG-4 AAC Low complexity

MPEG-4 AAC Low complexity

and

MPEG-4 High Efficiency AAC

MPEG-4 High Efficiency AAC

formats with identical results

ochrons•3/23/25, 3:54 PM

[aac @ 0x560e66ce38c0] Number of scalefactor bands in group (46) exceeds limit (43).

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

Isaac McFadyen•3/27/25, 3:21 PM

You wouldn't want to use AI to compress, you'd want to use something like WebP, AVIF, etc
