are there any STT models on workers ai that support live streaming?

Ddan are there any STT models on workers ai that support live streaming?

I

No, and a lot of the new models being developed don't stream at all any more, actually. For example, Whisper/Nvidia Parakeet/Nvidia Canary don't support streaming, and instead recommend applications implement their own streaming by sending a request every <n> seconds while continuing recording (e.g. using multiple threads).

why language auto-detection is not supported on whisper-large-v3-turbo?

by default it transcribes to English, I would like to keep the original language, similar to what @cf/openai/whisper does

Also seeing this error. I've seen other posts saying it's a network issue at the workers-ai level, but I have yet to see a resolution or RCA

Is the solution to just add a fallback retry?

Notice how the completion_tokens are 256; the model wasn't actually done, but got cut off because max_tokens defaults to 256 as of a few weeks ago. You'll want to specify a higher maxTokens in your request in order to allow the model to finish it's thought.

Speaking of max_tokens, I can't seem to change max_tokens with the messages property in any chat model, and I have no clue why. I have done this via URL (api.cloudflare.com/client/v4/accounts/$CLOUDFLARE_ACCOUNT_ID/ai/run/@cf/meta/llama-3-8b-instruct).

I noticed that the opening <think> tag is missing

D

dmaretskyi•3/13/25, 7:07 PM

but also the model doesn't seem to recognize that it has access to a tool

I

Isaac McFadyen•3/13/25, 7:13 PM

Hmm yeah. Interesting.

I

Isaac McFadyen•3/13/25, 7:14 PM

Not sure about the latter but I'm guessing the leading <think> tag is missing because it's part of the prompt used by Workers AI (this is what tools like llama.cpp do in order to force the model to start it's response with thinking).

I

Isaac McFadyen•3/13/25, 7:14 PM

That said, for compatibility it should be manually added by Workers AI if it's part of the prompt.

I

Isaac McFadyen•3/13/25, 7:14 PM

CC @michelle ^ not 100% sure that's what's happening, but since multiple users are running into this it might be worth a bug fix

Isaac McFadyen•3/14/25, 5:16 AM

Per https://huggingface.co/blog/open-r1/update-3

Incidentally, this is also what DeepSeek does with their distilled models

So yes, guessing that the <think> tag is just being prefilled and Workers AI isn't adding it back into the response.

quick question. from the cloudflare workers ai, what's the best model for image compression?

Torianna•3/14/25, 10:50 AM

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

T

Torianna•3/14/25, 10:50 AM

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

T

Torianna•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

T

Torianna•3/14/25, 10:57 AM

I don't think there's any public models

T

Torianna•3/14/25, 10:58 AM

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

K

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

I

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.

just so I can check when this gets resolved

Ddmaretskyi do you have a public bug tracker for this?

Nope but if I don't hear back from Michelle in a while I can try to escalate to others.

Ddmaretskyi okay, thanks for your help!

Isaac McFadyen•3/14/25, 3:26 PM

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

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 }
}

}

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.

If I replace

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

I didn't create a token, it was created for me on the dashboard when I went to the AI Worker page

I applied as an Engineer at Cloudflare this past month, but I don't think I got past the resume screen. I live around the corner from the SF offices and have been there for a hackathon and lunch-and-learn HONO event the past 2 weeks. I can fix this issue: https://github.com/valdezm/dash.cloudflare.com/issues/1

Problem A REST Bearer token was created for me and does not show up in my Account API Tokens using these instructions: https://developers.cloudflare.com/workers-ai/get-started/rest-api/#1-get-api-t...

are there any STT models on workers ai that support live streaming?
